RS PRO Nitrile Rubber V Seal 31 mm Inside Diameter, 44 mm Outside Diameter, 7.5 mm Thickness 749-660

RS PRO 749-660 Nitrile Rubber V Seal is a high-quality sealing solution engineered for rotary shafts in demanding industrial environments. This seal features an inside diameter of 31 mm, an outside diameter of 44 mm, and a thickness of 7.5 mm, providing precise fitment for compatible shaft sizes.

Constructed from robust nitrile rubber (NBR), the seal offers impressive chemical resistance and durability, making it ideal for applications where exposure to oils, lubricants, and contaminants is common. The NITRILE 60 SHORE hardness ensures a balance between flexibility and strength, enabling effective sealing under variable conditions.

The V-ring all-rubber design mounts directly onto the shaft. Its elastic body firmly grips the rotating shaft, allowing the lip to provide an axial seal against the counter face, bearing race, or bore housing. This ensures reliable containment of fluids and protects against dust or external contaminants.

Wide tolerances in shaft sizes and the ability to accommodate considerable axial misalignment make this seal particularly advantageous for machinery requiring flexibility in component fitting. It can be stretched during installation without the need to dismantle surrounding assemblies, simplifying maintenance procedures.

RS PRO V Seal is highly effective on oval shafts and supports secondary sealing roles, protecting primary seals which might otherwise fail in hostile environments. Typical applications are found in electric motors, conveyor rollers, and other rotary motion systems.

The seal is suited for use in industrial maintenance, mechanical repairs, manufacturing facilities, fluid power equipment, and wherever reliable shaft sealing is a priority. It helps extend machinery life and maintain operational integrity.

Durable nitrile rubber construction for chemical resistance and longevity. Axial sealing performance suitable for rotary shafts and bearing housings. Accommodates variations in shaft diameter and shape, including oval shafts.

Hardness of NITRILE 60 SHORE for optimal mechanical strength. Commonly used in electric motors, conveyor rollers, and fluid power systems. Simplifies maintenance by allowing stretching without disassembly. Protects primary seals from hostile environmental damage.
