SKF Nitrile Rubber (NBR) Seal, 19 mm ID, 32 mm OD, 7 mm

This seal is a radial rotary shaft seal designed to separate rotating and stationary components and retain lubricants in moving machinery. It features a rubber outer diameter and a single elastomeric sealing lip with an auxiliary non-contact lip and garter spring to maintain contact with the shaft in contaminated environments. The product is suitable for oil or grease sealing in machines operating at moderate temperatures and rotational speeds.

• Nitrile rubber lip provides chemical resistance for oil and grease
• Auxiliary non-contact lip improves exclusion of dust and debris
• Garter spring maintains consistent lip pressure during rotation
• Metal-reinforced rubber outside diameter eases housing installation
• Accepts shaft misalignment while maintaining sealing function

• Suitable for servo and stepper motor shafts in automation systems
• Ideal for gearbox and reducer oil retention in mechanical drives
• Used with rotating electromechanical assemblies in electronics manufacturing
• Can be used for rotating Seals in electrical motors and generators
• Used for maintenance replacement on bearing housings in machinery

It operates continuously from −40°C up to 100°C with short-term peaks to 120°C.

Circumferential speed may reach 3.92 m/s, corresponding to a maximum rotational speed of 3,960 r/min for the specified shaft diameter.

A rubber outside diameter designed for a 32mm housing bore provides an interference fit when the housing accommodates a rubber metal-reinforced OD.

The design tolerates a pressure differential of 0.03 N/mm while preserving lubricant retention.

A thin sleeve for shaft repair is typically used to restore a proper running surface before refitting the seal.
