SKF Nitrile Rubber (NBR) Seal, 22 mm ID, 32 mm OD, 7 mm

This seal is a rotary shaft sealing solution designed to separate rotating and stationary components in machines, preventing lubricant loss and contaminant ingress. It features a rubber exterior for press-fit installation into housings and a single elastomeric sealing lip retained by a garter spring, making it suitable for oil or grease retention in industrial equipment.

• Nitrile rubber lip provides resistance to common lubricants
• Garter spring maintains consistent radial load for sealing performance
• Rubber outside diameter enables secure housing press-fit
• Permits circumferential speeds up to 4.5 m/s for moderate-speed shafts
• Withstands continuous temperatures from -40°C to 100°C

• Suitable for sealing shafts in automation actuators with oil lubrication
• Ideal for grease-retained bearings in electrical motors
• Used for rotary Seals in mechanical assemblies subject to misalignment
• Can be used for bearing-seal replacement in rotating equipment

It is intended for use with a 22mm shaft and a 32mm housing bore, with a 7mm axial width.

Short-term exposure up to 120°C is acceptable, allowing limited high-temperature events.

Maximum rotational speed is 3900 r/min, limiting its use to moderate-speed applications.

The design accommodates minor misalignment due to the flexible sealing lip and spring preload.

A speedi-sleeve can be used where shaft damage requires a repair sleeve before fitting the seal.
