What's the difference between sealed (2RS) and shielded (2Z) bearings?

Sealed bearings (2RS) use rubber contact seals that retain grease and block contaminants — ideal for dusty or wet environments. Shielded bearings (2Z) use metal shields with lower friction but less protection against fine dust. For most industrial applications 2RS is the safer choice.

Which internal clearance should I choose — C2, C3 or C4?

C3 is the most common clearance for general industrial use as it allows for thermal expansion. C2 is tighter for precision applications, while C4 suits high-speed or high-temperature setups. If you are unsure, C3 is the safe default.

What are the most common causes of premature bearing failure?

The main culprits are inadequate or incorrect lubrication, contamination from dirt or moisture, misalignment and overloading. Correct installation with the right tools and a regular re-lubrication schedule can dramatically extend bearing life.

Can I swap my bearing for a different brand?

Yes. Bearings are largely standardised by ISO dimensions, so SKF, FAG, Timken and ISB equivalents are interchangeable by part number and dimensions. Use our Competitor SKU Converter to cross-reference your part.
