How Buyers Should Source Plain Bearings
On Machrio, the plain bearings category is also carrying oil seal intent, so the page needs to explicitly help buyers compare radial shaft seals by size, lip geometry, compound, and operating environment. Buyers searching oil seals are rarely browsing casually; they want to cross-check fit and failure risk quickly.
What to Compare
- Start with shaft diameter, housing bore, width, and whether the application is oil retention, dust exclusion, or both.
- Compare single-lip, dual-lip, and spring-loaded designs based on contamination risk, shaft finish, and direction of sealing duty.
- Match the elastomer to temperature, lubricant, speed, and chemical exposure instead of assuming NBR, FKM, and PU are interchangeable.
Common Applications
- Motors, pumps, gearboxes, reducers, and rotating process equipment
- Maintenance replacement for leaking or contaminated shaft-seal positions
- Procurement workflows where cross-reference fit and material confirmation matter before order
RFQ Checklist
- Record shaft diameter, housing bore, seal width, and rotation or pressure conditions.
- Confirm lip design, spring requirement, and elastomer compatibility with lubricant and temperature.
- Check whether dust exclusion, washdown, or abrasive contamination is part of the service environment.
