- Best used for high radial loads and where the bearing rolling motion occurs on the outer diameter surface
- Made from premium high carbon high chromium steel
- Uses a full complement of greased rollers that offer maximum radial load capacity
- Available with a crowned outside diameter (YCRSC inch series) and seals (YCRS inch series) for the inch product
- Available with a standard crowned outside diameter (without the .DZ) shields ("ZZ" for STO RSTO and NUTR series) or seals (.2RS for NA2200 series) for the metric product
- RSTO metric series requires a hardened and machined shaft/stud no inner ring included
How do I choose the right type of bearing for my application?
Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
