SKF Seal, 65mm Inside Diameter, 90mm Outside Diameter - 65X90X10 HMS5 RG


This seal is a rotary shaft sealing component designed to separate rotating and stationary parts in machines, preventing oil or grease leakage in dynamic interfaces. It features a rubber outer circumference and a single elastomeric sealing lip retained by a garter spring, suitable for installations where a resilient housing fit and continuous rotary sealing are required.

Features & Benefits


• Nitrile rubber lip provides chemical resistance for oil and grease handling
• Rubber outside diameter ensures secure interference fit in bores
• Garter spring maintains radial load for consistent sealing performance
• Withstands circumferential speeds up to 8.9 m/s for high-speed shafts
• Operates between −40°C to 100°C to cover standard industrial ranges
• Tolerates short temperature peaks to 120°C for transient conditions

**Applications**


• Suitable for motor shafts in automation equipment
• Ideal for gearboxes requiring oil containment
• Used with rotating electrical machine assemblies
• Can be used for shafts in mechanical drives and conveyors
• Used for sealing bearings in industrial electronics housings

What rotational speeds can it withstand in service?


It is rated for rotational speeds up to 2640 r/min under specified operating conditions.

How does the seal cope with shaft misalignment?


The elastomeric sealing lip and garter spring combination accommodates minor shaft offset through elastic deformation.

What construction ensures a firm fit in the housing bore?


The outside diameter is formed from rubber with metal reinforcement to provide interference fit and dimensional stability in a 90mm bore.

Is the material suitable for common lubricants?


The sealing lip is MADE from nitrile rubber (NBR), which is compatible with many oils and greases used in industrial applications.

What pressure differential can the seal handle across the lip?


The design is specified for a pressure differential of 0.03 N/mm, appropriate for typical low-pressure sealing tasks.
