SKF Seal, 27mm Inside Diameter, 47mm Outside Diameter - 27X47X7 HMSA10 RG

This seal provides a rotary shaft sealing solution for interfaces between rotating and stationary components, designed to retain oil or grease and reduce ingress of contaminants in mechanical assemblies. It features a rubber outer diameter and an elastomer sealing lip with an auxiliary non‑contacting lip and spring support to maintain effective shaft contact in polluted environments.

Features & Benefits

• Auxiliary non‑contacting lip improves contamination exclusion
• Garter spring maintains lip radial pressure for consistent sealing
• Accommodates misalignment to reduce installation stress
• High pumping rate assists Rapid lubricant circulation
• Suitable for operation from -40°C to 100°C

Applications

• Suitable for bearing housings in automation equipment
• Ideal for gearboxes handling lubricating oil or grease
• Used with rotating shafts in electrical motor assemblies
• Can be used for hydraulic pumps in mechanical systems

What maximum shaft speed can it tolerate?

It is rated for rotational speeds up to 3780 r/min under specified conditions.

How does the seal cope with short temperature spikes?

It withstands brief elevations to 120°C for intermittent operation.

What is the permitted peripheral shaft velocity?

The allowable circumferential speed is 5.34 m/s.

What pressure differential can the sealing lip handle?

The seal is specified for a pressure differential of 0.03 N/mm.

What material composes the primary sealing lip?

The lip is manufactured from nitrile rubber (NBR) to balance oil resistance and elasticity.
