RS PRO Nitrile Rubber V Seal, 9 mm ID, 17.5 mm OD, 5.5 mm Thickness, 60 Shore Hardness, Pack of 4 749-581

RS PRO 749-581 Nitrile Rubber V Seal is an all-rubber seal engineered for use on rotary shafts in a variety of mechanical and industrial applications. With an inside diameter of 9 mm, outside diameter of 17.5 mm, and a thickness of 5.5 mm, this seal provides secure and reliable sealing for small rotating assemblies.

Constructed from high-quality nitrile rubber (NBR), this V-ring seal offers resistance to abrasion and chemicals commonly encountered in industrial environments. The 60 Shore hardness level ensures the seal maintains its shape and effectiveness even with frequent shaft movement. The elastic body mounts directly onto the shaft, creating firm contact while the seal lip axially presses against the counter face, bearing race, or bore housing to prevent ingress of contaminants and loss of lubricants.

This V seal design accommodates considerable axial misalignment and is highly tolerant to variations in shaft diameters. It can be stretched onto shafts without needing to disassemble the entire unit, improving maintenance procedures and supporting long-term reliability. The seal also performs efficiently on oval shafts and provides a wide tolerance for differing shaft sizes.

The RS PRO 749-581 is applicable in diverse settings such as small electric motors, conveyor rollers, and as a secondary seal to protect primary seals which may not perform optimally in hostile environments. It is suitable for industrial, automation, and mechanical systems where shaft sealing is essential for smooth and contamination-free operation.

Durable nitrile rubber construction ensures long-lasting performance. 60 Shore hardness level maintains proper sealing and flexibility. V-ring shape specifically designed for rotary shaft sealing. Accommodates shaft misalignment and tolerances without loss of effectiveness.

Pack of 4 seals provides immediate replacements for critical applications.
