Seal Design Notes
- Seal construction
- Open bearing, with no integral seal or shield on either side.
- What it shields
- The bearing has no integral barrier against dust or water, or to retain grease. Protection and lubricant retention depend on the surrounding assembly.
- Effect on speed
- The open version provides the baseline grease-lubricated limiting speed for this base model. Use the speed listed in the specification table when selecting the bearing.
- Lubrication
- The factory table lists both grease and oil lubrication, with separate limiting speeds. Use the rating for the intended lubrication method.
- When to choose it
- Consider this version when the housing provides contamination control and the assembly supplies and retains the required lubricant.
