SKF Seal, 40mm Inside Diameter, 68mm Outside Diameter - 40X68X10 HMSA10 RG


This seal provides a radial sealing solution for interfaces between rotating and stationary components in industrial equipment. It features a rubber outer casing and a single elastomer lip designed to retain oil or grease while excluding contaminants, with a garter spring and an auxiliary non‑contact lip to maintain sealing performance in dusty environments.

Features & Benefits


• Designed for high circumferential speed up to 6.93 m/s to support fast shafts
• Operates across −40°C to 100°C continuous temperature range
• Withstands short temperature peaks to 120°C for transient conditions
• Auxiliary lip and dust lip enhance contamination exclusion during operation
• Garter spring ensures consistent radial contact for reliable sealing
• Accommodates shaft misalignment to reduce installation sensitivity

Applications


• Suitable for bearings in automation actuators and drives
• Ideal for motor shafts in electrical equipment
• Used with gearboxes requiring oil retention and dust exclusion
• Can be used for rotating assemblies in electronics manufacturing machinery

What shaft sizes does it accept?


It is intended for a shaft diameter of 40mm and is manufactured to fit corresponding housings.

How fast can the sealed shaft rotate?


The maximum permissible rotational speed is 3,300 r/min under the specified operating conditions.

What pressure differential can the seal tolerate?


The seal is rated for a pressure differential of 0.03 N/mm² in its intended applications.

Which sealing material contacts the shaft?


The sealing lip is MADE from nitrile rubber (NBR), providing oil and grease compatibility with common industrial lubricants.
