SKF Seal, 20mm Inside Diameter, 37mm Outside Diameter - 20X37X7 HMSA10 RG


This radial shaft seal is designed to separate rotating and stationary machine parts, providing fluid retention and exclusion of contaminants in equipment that handles oil or grease. It features a rubber outer diameter and an additional non‑contacting lip to improve protection in polluted environments, making it suitable for rotating shafts where maintaining lubricant and excluding debris are required.

Features & Benefits


• Garter spring maintains tight contact with shaft for consistent sealing
• Auxiliary non‑contacting lip increases contamination exclusion efficiency
• Nitrile rubber lip resists oil and grease for extended service life
• Rubber outside diameter aids secure press‑fit into housing bore
• Permits circumferential speeds up to 4.12 m/s for moderate‑speed applications

Applications


• Suitable for sealing 20mm shaft assemblies in gearboxes and motors
• Ideal for bearing housings requiring rubber OD installation
• Used with rotating drives in automation equipment handling lubricants
• Can be used for replacement of shaft Seals in industrial machinery

What temperatures can it operate within during normal service?


It functions between −40°C to 100°C with short‑term tolerance up to 120°C.

What rotational limits should be observed to avoid premature wear?


Maximum rotational speed is 3960 r/min

exceeding this may reduce seal life.

How does it handle pressure differences across the seal?


It is rated for a pressure differential of 0.03 N/mm, suitable for low‑pressure retention tasks.
