SKF Seal, 55mm Inside Diameter, 90mm Outside Diameter - 55X90X8 HMSA10 RG


This seal is a rotary shaft sealing component designed to separate rotating and stationary elements and to retain lubricants while excluding contaminants in machinery. It features an elastomeric sealing lip with an auxiliary non-contacting lip and an internal garter spring to maintain sealing performance under relative motion and polluted environments.

Features & Benefits


• Auxiliary lip boosts contamination exclusion in dusty conditions
• Garter spring maintains consistent radial pressure on the shaft
• Permissible circumferential speed 8.22m/s supports moderate-speed shafts
• Operates between −40°C to 100°C for broad thermal range
• Short-term temperature tolerance up to 120°C for transient peaks

Applications


• Suitable for gearboxes requiring oil retention and dust exclusion
• Ideal for electric motor shafts operating at up to 2880r/min
• Used with pump drives where grease sealing is needed
• Can be used in automation actuators subject to misalignment

What housing conditions does it accommodate?


The outside diameter is formed by a rubber element reinforced for press‑fit mounting into a housing bore to provide secure seating and vibration damping.

How does it cope with shaft misalignment?


The seal design includes flexibility in the elastomer lip geometry allowing it to tolerate moderate shaft eccentricity while preserving the seal interface.

What fluid types is it compatible with?


The sealing lip material is nitrile rubber (NBR), suitable for standard mineral oils and common lubricating greases within the stated temperature limits.

What rotational speeds can it handle continuously?


Continuous operation is rated up to 2880r/min, corresponding to the maximum acceptable circumferential speed for the specified shaft diameter.
