SKF Seal, 25mm Inside Diameter, 62mm Outside Diameter - 25X62X7 HMSA10 RG


This radial shaft seal provides a rotating-shaft barrier to retain lubricants and exclude contaminants in machinery. It features a rubber outside diameter and a single conventional sealing lip suited to oil or grease applications, with an auxiliary non-contacting lip and garter spring to maintain shaft contact in polluted environments.

Features & Benefits


• Permits circumferential speeds up to 5.03 m/s for moderate-speed shafts
• Withstands operating temperatures from -40°C to 100°C
• Accommodates short temperature excursions to 120°C for transient events
• Includes a garter spring to maintain lip pressure and sealing performance
• Dust lip improves exclusion of external contaminants during operation

Applications


• Suitable for sealing motor shafts in industrial drives
• Ideal for gearboxes requiring oil retention and contamination exclusion
• Used with rotating assemblies in automation equipment
• Can be used for bearing housings subject to particulate exposure

What shaft and housing dimensions does it suit?


It is specified for a 25mm shaft and a 62mm housing bore with a 7mm seal width.

What materials contact the lubricant and shaft?


The primary sealing element is nitrile rubber (NBR), chosen for compatibility with oil and grease media.

How does it handle misalignment between components?


The design tolerates slight misalignment through the elastomer lip geometry and flexible outside diameter.

What rotational speed limit should be observed?


The maximum recommended rotational speed is 3840 r/min under stated conditions.
