Model and configuration notes
The S suffix does not identify stainless steel. Catalogue dimensions are reproduced rather than recalculated from nominal inch sizes.
Information for your enquiry
Include the complete designation, quantity, mating dimensions or thread, load direction, motion and operating environment. Specify lubrication access and the seal arrangement where relevant. Catalogue dynamic and static ratings are different quantities; neither is an application-specific working-load or life guarantee.
Can I use another material or thread?
State the required configuration and drawing. Additional left-hand, material or sealing options need a confirmed full designation and are not generated automatically from the listed models.
What if a dimension is missing?
Request the current drawing for the selected designation. Blank values are retained from the source and are not filled from adjacent models or another series.
For a drawing-defined part or changed interface, see our custom bearing enquiry options.
