SKF Seal, 40mm Inside Diameter, 7mm Thickness - 40X55X7 HMSA10 RG

This rotary shaft seal is designed for use between rotating and stationary components, effectively accommodating a shaft diameter of 40mm and housing bore diameter of 55mm. The 7mm thickness provides a robust barrier against contaminants. Manufactured from nitrile rubber, this seal operates effectively in temperatures ranging from -40°C to +100°C, making it suitable for various dynamic sealing situations.

Features & Benefits

• High pumping rate to improve lubrication efficiency
• Enhanced contamination exclusion with auxiliary dust lip
• Incorporates a garter spring for reliable sealing
• Adapts well to misalignment between components
• Designed for optimal performance in polluted environments
• Supports a maximum circumferential speed of 6.93m/s

Applications

• Utilised in automotive to secure oil or grease
• Often found in machinery requiring dynamic sealing solutions
• Ideal for use in environments exposed to contaminants
• Commonly employed in industrial settings with rotating shafts

What temperature range can this seal operate within, and how does it contribute to reliability?

The seal operates effectively from -40°C to +100°C, enabling use in diverse environments. This wide temperature range ensures consistent performance, even under challenging conditions.

How does the Advanced design of the seal enhance its functionality?

The inclusion of a garter spring and an auxiliary dust lip optimally maintains the sealing pressure against the shaft, preventing leaks and prolonging service life, especially in areas with contaminants.

What is the significance of the seal's thickness in practical applications?

The 7mm thickness provides structural integrity and durability, which is essential for maintaining effective sealing performance over time in demanding environments.

Can this seal accommodate minor misalignments, and how is that beneficial?

Yes, the design allows for some misalignment, which helps prevent damage to both the seal and the components it protects, thus reducing maintenance needs and extending the lifespan of the assembly.
