SKF Seal, 40mm Inside Diameter, 72mm Outside Diameter - 40X72X10 HMSA10 RG


This seal is a rotary shaft seal designed to separate rotating and stationary machine parts and retain lubricants in moving assemblies. It features a rubber outside diameter and a single sealing lip with an auxiliary non‑contacting lip and garter spring to maintain sealing performance in contaminated environments. The component is intended for oil or grease applications across industrial machinery.

Features & Benefits


• Permissible circumferential speed 6.93 m/s for high‑speed operation
• Operating temperature range −40°C to 100°C for varied environments
• Short‑term temperature tolerance up to 120°C for transient heat events
• Garter spring maintains lip contact to reduce leakage risk
• Dust auxiliary lip improves exclusion of external contamination
• Accommodates shaft misalignment to reduce installation sensitivity

Applications


• Suitable for industrial gearboxes requiring oil retention
• Ideal for electric motor shaft sealing in automation systems
• Used with rotating assemblies in mechanical drives
• Can be used for maintenance replacement in pump shafts
• Used for sealing shafts in electrical drive units

What shaft sizes can this seal be fitted to?


It is intended for shafts with a 40mm diameter and is manufactured to suit a 72mm housing bore.

How does the material affect compatibility with lubricants?


The lip is MADE from NBR nitrile rubber, which offers compatibility with common oils and greases used in industrial applications.

What rotational speeds can it tolerate?


The seal is rated for up to 3,300 rev/min at the specified shaft diameter and speed limits.

How is pressure differential handled by the component?


The design withstands a pressure differential of 0.03 N/mm while maintaining dynamic sealing.

Are metric measurements used for specification matching?


Yes, all dimensions and performance data are provided in the metric system for precise component selection.
