SKF Nitrile Rubber (NBR) Radial Shaft Seal, 140 mm ID, 170 mm OD, 12 mm

This radial shaft seal provides a sealing Interface for rotating shafts to retain lubricants and exclude contaminants in mechanical systems. It is manufactured from nitrile rubber and is designed for rotary applications where a balance of flexibility and resistance to common oils is required. The component Interfaces between shaft and housing to maintain operational integrity in driven assemblies.

• Nitrile rubber construction offers oil compatibility for extended service
• Rotary seal design reduces leakage on rotating interfaces
• 12 mm cross-section thickness enhances contact resilience under load
• High inside-diameter tolerance supports 140 mm shafts with consistent fit
• Outside-diameter provision ensures stable housing engagement at 170 mm

• Suitable for gearboxes with rotating shaft Seals
• Used with agricultural machinery drivetrains requiring oil retention
• Ideal for industrial motors needing lubricant containment
• Can be used for pump shaft sealing in manufacturing plants
• Used for maintenance replacement of worn radial Seals

The elastomeric composition is nitrile rubber which balances resistance to hydrocarbon-based lubricants with elastic recovery for lip contact.

The sealing element is intended to fit a 140 mm shaft inside and to locate against a 170 mm bore outside while maintaining a 12 mm radial section for proper contact.

Adequate housing bore roundness and shaft surface finish must be maintained so the seal lip can engage correctly without distortion of the 12 mm thickness.

Its configuration is tailored to dynamic operation, maintaining a consistent Interface under rotation to control lubricant retention and ingress of contaminants.
