SKF Radial Shaft Seal, 42mm Inside Diameter, 56mm Outside Diameter - 42X56X7 HMSA10 RG
This radial shaft seal provides rotary sealing for shafts in rotating equipment, designed to prevent fluid loss and exclude contaminants during operation. It is constructed from nitrile rubber and intended for use where a resilient lip seal is required on rotating shafts.
Features and Benefits:
• Nitrile rubber material offers chemical resistance and elastic sealing
• Rotary sealing profile reduces leakage under rotational motion
• Robust 7mm thickness resists extrusion and lip deformation
• Engineered for continuous contact to limit contamination ingress
• Suitable for moderate temperature ranges typical of NBR compounds
• Rotary sealing profile reduces leakage under rotational motion
• Robust 7mm thickness resists extrusion and lip deformation
• Engineered for continuous contact to limit contamination ingress
• Suitable for moderate temperature ranges typical of NBR compounds
Applications
• Suitable for sealing motors with rotating shafts
• Used for oil containment in gearboxes and housings
• Ideal for maintenance replacement in rotating assemblies
• Can be used for pumps requiring shaft lip seals
• Used with drive shafts in light industrial equipment
• Used for oil containment in gearboxes and housings
• Ideal for maintenance replacement in rotating assemblies
• Can be used for pumps requiring shaft lip seals
• Used with drive shafts in light industrial equipment
What internal and external diameters does it fit?
It fits shafts with a 42mm internal bore and housings with a 56mm external seat.
What material characteristics affect seal lifespan?
The nitrile rubber composition resists oil swelling and provides wear resistance under frictional contact.
How does the seal handle shaft misalignment?
The lip geometry tolerates minor shaft run-out while maintaining contact to reduce leakage.
Which mechanical condition influences installation tightness?
Housing bore roundness and shaft finish determine interference fit and sealing effectiveness.
