SKF Radial Shaft Seal, 85mm Inside Diameter, 100mm Outside Diameter - 85X100X9 HMSA10 RG

This radial shaft seal provides a rotating-shaft sealing solution designed to prevent fluid leakage and exclude contaminants in rotating equipment. It is MADE from nitrile rubber and intended for applications where a resilient lip material is required to maintain contact with a moving shaft and preserve system integrity.

Features and Benefits:

• Nitrile rubber construction resists common oils and greases
• Rotary shaft seal design sustains continuous shaft motion
• 9 mm cross-section delivers consistent sealing contact
• 85 mm inner diameter ensures snug shaft engagement
• 100 mm outer diameter offers stable housing fit

Applications

• Suitable for sealing rotating gearbox shafts
• Ideal for hydraulic motor and pump interfaces
• Used with industrial drive shafts requiring oil retention
• Can be used for replacements in maintenance tasks
• Appropriate for rotating assemblies needing dust exclusion

What material characteristics affect chemical compatibility?

The lip material is nitrile rubber, which provides compatibility with many lubricants and oils commonly used in rotating equipment.

How does the seal accommodate shaft and housing tolerances?

The design uses a flexible sealing lip that conforms to the shaft at the specified inner diameter while the outer diameter locates in the housing bore.

What physical dimensions determine fitment?

Fit depends on the internal diameter, external diameter and cross-section thickness, which correspond to shaft size and bore depth.

How does the seal perform during continuous rotation?

The sealing geometry is configured for rotary applications to maintain contact under steady rotational motion.
