Industrial Lubricants Attributes | Anglera Schema Library

Core

Every SKU needs these. Without them the record is not a product, it is a row.

AttributeExampleWhy it matters

Lubricant Type

enum

Anti-wear hydraulic oil (ISO-L-HM)

Sets which specs apply. An ISO-L-HM anti-wear oil and an ISO-L-HV high-VI oil are both "hydraulic oil" and are not interchangeable.

Base Oil Type

enum

Synthetic (PAO)

Drives drain interval, temperature range and price. Mineral, PAO, ester, PAG and silicone behave differently, and seal compatibility follows the base oil.

ISO Viscosity Grade

enum

46

The first filter every buyer touches. An ISO 3448 bucket measured at 40 °C. The OEM plate names a grade and the buyer is matching it exactly.

Kinematic Viscosity @ 40 °C

number · cSt (mm²/s)

46.2

The measured number behind the grade (ASTM D445). On a grease this is the base oil viscosity — what bearing selection needs. NLGI grade won't tell you.

NLGI Consistency Grade

enum

2

Grease consistency per ASTM D217, 000 to 6. Centralized systems need 0 or 00; a grease gun wants 2. Wrong grade and the system will not feed.

Thickener Type

enum

Lithium complex

Decides compatibility with the grease already in the bearing, and the upper temperature limit. Lithium complex and polyurea do not mix.

Container Size

number · gal, L, lb, oz

5

Buyers order by pack, not by fluid. Oils run quart to 275 gal tote; greases run 14 oz cartridge to 400 lb drum.

Container Type

enum

Pail

Cartridge, tube, pail, keg, drum, tote and bag-in-box each imply different dispensing equipment on the plant floor.

Manufacturer Part Number

identifier

105841

The number the buyer types. Cross-references, OEM lookups and every RFQ key on the MPN, not on your internal SKU.

GTIN / UPC

identifier

GTIN-14, e.g. 00012345678905

Required by marketplaces and by any buyer scanning into a storeroom crib or industrial vending machine.

Differentiating

What buyers actually compare on. This is where catalogs win or lose the filter.

AttributeExampleWhy it matters

Viscosity Index

number

104

How much viscosity falls as the oil heats, per ASTM D2270. Separates HM fluids (~100 VI) from HV/HVLP multigrades (140+) for outdoor and mobile systems.

Operating Temperature Range

range · °C

-25 to 150

The question every buyer actually asks. Needs min and max as numbers, not "high temperature" sitting in the description.

Flash Point (COC)

number · °C

224

Cleveland Open Cup, ASTM D92. Drives hot-surface safety review and the hazmat classification that decides how the drum ships.

Pour Point

number · °C

-36

ASTM D97. The lowest temperature the oil still flows — the difference between a hydraulic system that starts at -30 °C and one that does not.

Anti-Wear / EP Additive Chemistry

enum

Zinc-free (ashless)

Zinc (ZDDP) vs ashless vs sulfur-phosphorus EP. Turbine and yellow-metal systems bar ZDDP; EP gear oils require it. Not interchangeable.

Compliance & identifiers

Standards, regulatory data, and the identifiers channels reject you for missing.

AttributeExampleWhy it matters

NSF Nonfood Compound Category

enum

H1

H1 = incidental food contact per 21 CFR 178.3570; H2 = no contact; 3H = release agent. Food plants filter here first. Carry the registration number with it.

Specifications & OEM Approvals

text

DIN 51524-2 (HLP); Denison HF-0; Eaton M-2950-S; Cincinnati P-70

The field that wins the RFQ. Approvals are pass/fail: the OEM either lists the fluid, or the warranty argument starts.

Country of Origin

enum

United States (US)

Customs, and required on public-sector and Buy American-clause orders. Also a routine line on punchout and CIF catalog feeds.

The fields that aren't in the schema at all

What most industrial lubricants catalogs are missing.

The table above is the schema most catalogs already have. These are the attributes that usually aren't in it — each one surfaced by a signal from the live market rather than by an audit of what's already there. This is what Anglera's Schema Foundry does on a real catalog, in this category.

Competitor signal

+ Thickener Type

Every grease PDS names the thickener — lithium complex, polyurea, calcium sulfonate, clay. Distributor grease listings carry NLGI grade and base oil type and stop there. No thickener facet exists.

Grease incompatibility. Polyurea pumped into a lithium complex bearing softens the charge and it purges; the bearing runs dry and the distributor owns the failure.

Supplier signal

+ Specifications & OEM Approvals

Approval lists (DIN 51524-2 HLP, Denison HF-0, Eaton M-2950-S, Cincinnati P-68/P-69/P-70) live in the PDS PDF. Buyers ask for them by name in the RFQ; the catalog record has no field to answer from.

The RFQ goes to whoever can prove the approval. No approval field means no answer, and the line is quoted by the competitor who documented it.

Search signal

+ NSF Registration Number

Buyers search "NSF H1 registered gear oil" and "NSF registration number". Site search returns hits only where a marketer happened to type H1 into the description — the number itself is stored nowhere.

Food and beverage plants will not stock a lubricant they cannot cite in an audit. The SKU is excluded from the approved list regardless of how it is formulated.

Marketplace signal

+ Zinc-Free / Ashless Formulation

Marketplace listings for R&O and turbine oils compete on the word "ashless" in the title because there is nothing to filter on. Distributor records say nothing about additive chemistry.

Ashless is a hard OEM requirement in steam and gas turbine systems. Without the field a zinc AW oil ships against an R&O spec, and the varnish shows up months later.

Review signal

+ Operating Temperature Range

Product copy says "high temperature grease". Returns and reviews cite the actual number — run past its upper limit, or would not pump in a cold cell. Min/max °C is never stored as two numbers.

No temperature filter, so buyers cannot size for a -30 °C outdoor conveyor or a 150 °C oven bearing. The wrong grease ships, bleeds out, and comes back.

How Schema Foundry finds these

Messy in, governed out.

The same value, spelled every way industrial MRO suppliers spell it. A filter only works once they agree.

ISO Viscosity Grade

ISO VG 46ISO 46AW-46VG4646 wtGrade 46

46

AW-46 folds additive type into the grade. Split them: ISO VG is a viscosity bucket per ISO 3448, AW is the additive package.

NLGI Consistency Grade

NLGI 2No. 2#2EP2Grade 2NLGI Grade #2

2

EP2 conflates consistency with EP additives. An NLGI 2 grease may or may not be EP. Keep the two fields apart.

Thickener Type

Lithium ComplexLi-ComplexLiXComplex lithium soapLi CxLithium 12-OH complex

Lithium complex

Lithium and lithium complex are different thickeners with different limits and compatibility. Collapsing both to "lithium" fails bearings.

Container Size / Type

5 gal5 gallon pail18.9 L35 lb pail5 GAL PLPail-5gal

5 gal / Pail

Oils sell by volume, greases by mass. A 5 gal pail of grease is ~35 lb. Store size, unit of measure and container type as three fields.

What buyers ask

Every one of these should be answerable from the attributes above. If it isn't, that's a gap.

Is this ISO 46 approved for Denison HF-0 and Eaton M-2950-S?
Will this grease mix with the lithium complex already in the bearing?
Is it NSF H1 registered, and what's the registration number?
Is this ashless? The turbine OEM won't allow ZDDP in the system.
What's the base oil viscosity of this NLGI 2 grease at 40 °C?
How cold can it get before this stops pumping?
Does "5 gal" mean a 5-gallon pail or 35 lb of grease?
What's the flash point and UN number — can this ship by ground?

What channels require

The same SKU, different mandatory fields per destination.

Industrial Lubricants data, in practice

Why isn't ISO VG enough to identify a hydraulic oil?

ISO VG is one bucket at one temperature. Two ISO 46 fluids can be an HM anti-wear oil around 100 VI and an HV multigrade above 140, which behave differently on a cold morning. Beyond that, additive chemistry (zinc AW vs ashless) and the approval list (DIN 51524-2 HLP or Part 3 HVLP, Denison HF-0, Eaton M-2950-S, Cincinnati P-68/P-69/P-70) decide whether the fluid is allowed in the system at all. A buyer filtering to ISO 46 has narrowed the shelf, not chosen the product. Carry viscosity index, additive chemistry and approvals as their own fields, or the last three questions get answered by a phone call.

Which attributes do greases need that oils don't?

Four. NLGI consistency grade (ASTM D217) — a centralized system needs 0 or 00, a grease gun wants 2. Thickener type — lithium complex, polyurea, calcium sulfonate, aluminum complex, clay — which sets the temperature ceiling and, critically, compatibility with whatever is in the bearing now. Base oil viscosity at 40 °C, because bearing selection runs on the oil viscosity, not on the NLGI number. And dropping point (ASTM D2265), which bounds the useful upper temperature. Catalogs that treat grease as "oil with a consistency number" carry the first and skip the rest.

What's the difference between "food grade" and NSF H1 registered?

"Food grade" is marketing copy. NSF registration is a specific, checkable fact. H1 covers lubricants with possible incidental food contact and must be formulated to 21 CFR 178.3570. H2 is for equipment where no contact is possible. 3H is a release agent for direct food contact. Each registered product carries a registration number listed in the NSF nonfood compounds database, and that number — not the phrase — is what a plant auditor asks for. ISO 21469 certification is a separate, stricter scheme covering manufacturing hygiene. Store the category and the registration number as distinct fields.

How should container size be modeled for lubricants?

As three fields, not one string. Size (numeric), unit of measure, and container type. Oils are sold by volume — 1 qt, 1 gal, 5 gal pail, 55 gal drum, 275 gal tote. Greases are sold by mass — 14 oz cartridge, 35 lb pail, 120 lb keg, 400 lb drum — and a 5 gal pail of grease weighs about 35 lb, so "5 gal" and "35 lb" can describe the same pack. Punchout and CIF catalogs price against a single unit of measure, so a size baked into the description cannot be validated, converted, or filtered.
