Seal Design Notes
- Seal construction
- RZ sealing rings made of nitrile rubber (NBR) on both sides.
- What it shields
- The rings help limit contaminant entry and grease escape on both sides. A water-resistance rating and contact geometry are not specified in the factory table.
- Effect on speed
- The listed grease-lubricated limiting speed is 100% of the open version for the same base model. Check that model-specific limit against the intended operating speed.
- Lubrication
- The factory table specifies grease lubrication and provides no oil-lubricated limiting speed. Obtain confirmation before selecting this version for an oil-lubricated system.
- When to choose it
- Consider 2RZ when a grease-lubricated assembly needs NBR rings on both sides while retaining the listed open-version grease speed. Confirm protection and grease-life requirements.
