SKF Seal, 25mm Inside Diameter, 6mm Thickness - 25X37X6 HMSA10 RG


This seal is a rotary shaft sealing solution designed to separate rotating and stationary parts in machinery, preventing lubricant loss and contamination ingress. It features a rubber outer profile with a single main sealing lip and an auxiliary non‑contacting lip to maintain effective exclusion of dirt and minimise leakage in polluted environments.

Features & Benefits


• Garter spring maintains consistent lip contact and sealing force
• Auxiliary lip improves contamination exclusion in dusty conditions
• Nitrile rubber compound resists oil and grease exposure
• Accommodates shaft misalignment to reduce wear
• Permits circumferential speed up to 5.03 m/s for moderate rpm usage

Applications


• Suitable for automation gearboxes requiring oil retention
• Ideal for electrical motor shafts in industrial equipment
• Used with bearings in mechanical drive assemblies
• Can be used for maintenance replacement in rotating housings

What temperature range can it operate within?


It supports continuous service from −40°C to 100°C and short peaks to 120°C.

What rotational speed limits should be observed?


Maximum rotational speed is 3,840 r/min, corresponding to a circumferential speed ceiling of 5.03 m/s.

How does the seal handle pressure differences?


The design tolerates a pressure differential of 0.03 N/mm, suitable for low‑pressure sealing applications.

What outer construction aids installation in housings?


The outside diameter is rubber with metal reinforcement to ensure secure seating in the bore.

Which shaft and bore sizes is it intended for replacement use with?


It is matched to a 25mm shaft and a 37mm housing bore with a 6mm section width.
