SKF Seal, 28mm Inside Diameter, 42mm Outside Diameter - 28X42X8 HMSA10 RG


This seal is a rotary shaft sealing component designed to separate rotating and stationary parts and retain lubricants in machinery. It uses an elastomer sealing lip and a rubber outer diameter to provide contact with the housing while managing shaft contamination and fluid retention in mechanical systems.

Features & Benefits


• Nitrile rubber lip for oil and grease resistance
• Auxiliary non-contacting lip improves contamination exclusion
• Garter spring maintains consistent shaft contact
• Operates at circumferential speed up to 5.49 m/s
• Tolerates shaft misalignment during rotation

**Applications**


• Suitable for motors and gearboxes in industrial automation
• Ideal for electrical drives requiring oil containment
• Used with rotating shafts in precision electronics assemblies
• Can be used for maintenance replacement in mechanical equipment

What shaft and housing sizes will it fit?


It is manufactured to fit a 28mm shaft and a 42mm housing bore with an 8mm seal width.

How does the design cope with particulate contamination?


A secondary dust lip combined with a garter spring reduces ingress by keeping the primary lip aligned and offering an extra barrier without shaft contact.

What limits apply for intermittent high-temperature exposure?


Short-duration temperature excursions are acceptable up to 120°C beyond the continuous 100°C rating.

What rotational speeds can be handled?


The component is suitable for rotational operation up to 3,720 r/min consistent with its maximum circumferential speed.

Is this compatible with metallic housing bores?


The outer diameter is rubber with metal reinforcement, allowing secure seating in metal housings while accommodating minor bore imperfections.
