What is OKS 432?
OKS 432 is a grease used for rolling bearings, sliding bearings, and hot air fans. A useful replacement review should go beyond a simple cross-reference and verify the product definition, operating conditions, lubricant chemistry, and the reason a maintenance or procurement team needs another sourcing option.
The lubrication-temperature profile is -15°C to +150°C normal; up to +200°C maximum, base oil technology is mineral oil, the required thickener base is aluminum complex soap, the NLGI grade is 2. These details are the starting point for technical matching because they affect film stability, pumpability, separation risk, and service life under real equipment conditions.
Typical demand for OKS 432 alternatives is driven by regional availability, long lead times, price changes, distributor coverage, or lubricant standardization across multiple plants. At this stage, the goal is to define a qualified technical requirement that can be reviewed against source documents, availability, and private-label sourcing options.

Why temperature matching matters
OKS 432 is being evaluated against a -15°C to +150°C normal; up to +200°C maximum lubrication-temperature requirement. Before sourcing an alternative, maintenance teams should check continuous temperature, peak temperature, startup conditions, contamination exposure, load, speed, and relubrication interval for the actual lubrication point.
Why lubricant chemistry matters
The base oil technology is mineral oil. Base oil chemistry affects evaporation loss, oxidation resistance, low-temperature behavior, and compatibility with the existing lubricant in the lubrication point. If the site is changing brands, the new product should be reviewed for chemistry compatibility and purge or changeover requirements.
Why thickener and consistency matter
The required thickener base is aluminum complex soap. The required NLGI grade is 2. Thickener system and consistency influence mechanical stability, water resistance, oil release, and how the lubricant stays in place. A replacement that matches temperature but differs sharply in thickener or consistency may behave differently under vibration, load, or repeated heating cycles.
Where the matched specification applies
Rolling bearings
OKS 432 can be evaluated for bearing positions where heat, load, seal material, speed, and relubrication interval are known. When replacing it in a bearing, the alternative should be checked for oil separation, consistency retention, and compatibility with the existing maintenance interval across -15°C to +150°C normal; up to +200°C maximum.
Sliding bearings
OKS 432 can be evaluated for bearing positions where heat, load, seal material, speed, and relubrication interval are known. When replacing it in a bearing, the alternative should be checked for oil separation, consistency retention, and compatibility with the existing maintenance interval across -15°C to +150°C normal; up to +200°C maximum.
Hot air fans
OKS 432 can be assessed for hot air fans where the operating temperature, contact materials, load, contamination exposure, and lubrication interval are known. Because the base oil technology is mineral oil, chemistry matching should be part of the approval step.
Converters
OKS 432 can be assessed for converters where the operating temperature, contact materials, load, contamination exposure, and lubrication interval are known. Because the base oil technology is mineral oil, chemistry matching should be part of the approval step.
Ladles
OKS 432 can be assessed for ladles where the operating temperature, contact materials, load, contamination exposure, and lubrication interval are known. Because the base oil technology is mineral oil, chemistry matching should be part of the approval step.

Validation plan before approval
Confirm the real operating window
Do not approve a proposed match only because the published temperature range looks similar. Record the continuous running temperature, short peak temperature, startup and shutdown conditions, and whether the lubrication point is exposed to washdown, dust, process chemicals, or outdoor weather. This prevents a replacement from passing on paper while failing in the real machine environment.
Check material and lubricant compatibility
Before switching from OKS 432, compare the current lubricant with the proposed product for base oil, thickener, additives, seal compatibility, and whether old grease must be purged. If mixed greases are likely to remain in bearings, housings, or lubrication lines, a technical reviewer should review compatibility guidance before starting the changeover.
Run a controlled first-use review
For critical equipment, introduce any proposed match through a limited maintenance trial. Track bearing temperature, noise, vibration, leakage, relubrication volume, lubricant condition, and operator feedback over the first service interval. The result gives purchasing and engineering a shared basis for approval instead of relying only on a catalog match.
Procurement review points
- Submit the requirement so a technical reviewer can classify any proposed match as an alternative, equivalent, or functional replacement for OKS 432. These terms are not identical: an equivalent implies closer technical alignment, while an alternative may still need engineering review.
- Request current TDS and SDS documents, packaging options, lead time, MOQ, shelf life, and country or region availability before changing the approved vendor list.
- If the site uses OKS 432 in multiple applications, separate the approval by lubrication point. A product that works in one bearing position may not automatically be approved for higher speed, higher load, washdown, or different relubrication intervals.
- Document the reason for change, the approval evidence, the first-use date, and the maintenance result. This makes future procurement audits and repeat orders easier.
Specification match request
This page focuses on document-backed specification matching for OKS 432. The review prioritizes temperature range, base oil, thickener, NLGI or consistency, application duty, and evidence quality before a proposed match is used in purchasing or maintenance planning.

FAQ
Can OKS 432 be replaced?
OKS 432 can be replaced in many maintenance programs, but the replacement should be validated against the same technical envelope rather than approved by name alone. Start with temperature range, base oil chemistry, thickener system, NLGI or consistency data, and the exact application point. Then compare the latest TDS and SDS documents with the operating conditions on site. For critical equipment, use a controlled first-use trial before approving a plant-wide substitution.
What is equivalent to OKS 432?
This page is designed to define the sourcing requirement rather than claim a fixed equivalent. A true equivalent needs evidence that the operating temperature, lubricant chemistry, thickener system, application duty, and material compatibility are close enough for the actual lubrication point. Share the TDS, SDS, and site duty cycle so a technical reviewer can prepare a documented match request before the approved product list is changed.
Can OKS 432 be used in bearings?
OKS 432 may be used in bearing or general lubrication points only when the bearing type, speed, load, temperature, seal material, and relubrication interval match the documented product profile. A proposed replacement should be checked for NLGI grade, thickener compatibility, base oil chemistry, and oil separation behavior before changing the approved lubricant.
What temperature range should an equivalent support?
An equivalent should support the real operating envelope of the lubrication point, not just a headline number. Always compare continuous temperature, peak temperature, ambient conditions, load, speed, contamination exposure, and relubrication interval before approval.
How should replacement products be validated?
Validate replacements with document review first, then a limited trial. Check the TDS, SDS, application point, temperature range, base oil, thickener, NLGI grade, seal compatibility, load, speed, and relubrication interval. After that, run a controlled first-use review on the real equipment and track temperature, noise, vibration, leakage, lubricant condition, and maintenance feedback. If the trial is stable, the proposed match can move from review to approval.
What documents should be checked before replacing OKS 432?
Check the latest TDS, SDS, manufacturer product page, OEM maintenance guidance, and any site-specific lubrication standard before replacing OKS 432. PDF source documents are especially important because industrial lubricant specifications are often more complete than product web pages. The review should capture temperature range, base oil, thickener, consistency, drop point if available, material compatibility, safety handling, and any limitations stated by the manufacturer.
What is the biggest risk when switching from OKS 432?
The biggest risk is approving a substitute without validating the actual duty cycle against the -15°C to +150°C normal; up to +200°C maximum temperature requirement, seal compatibility, contamination exposure, and relubrication interval. A replacement can look similar in a table but behave differently under heat, load, vibration, or mixed-lubricant conditions. For important equipment, the safer path is document review, engineering confirmation, and a monitored first-use trial before plant-wide rollout.
