Product Description
The RS PRO 749-626 nitrile rubber (NBR) V seal is a precision-engineered component designed to provide effective sealing solutions for rotary shaft applications. This V-type seal is constructed from durable nitrile rubber, renowned for its resistance to oils, grease, and many industrial chemicals, ensuring long service life and reliable performance in demanding environments.
Measuring 18 mm in inside diameter and 29 mm in outside diameter, with a robust 7.5 mm thickness, the seal is purpose-built to fit a wide range of shaft diameters typically found in industrial machinery. Its V-shaped profile is engineered specifically to maintain strong axial contact with the counter face - such as bearing races or bore housings - while the elastic body holds itself securely on the rotating shaft, creating a highly effective dynamic seal.
The nitrile construction enables the seal to accommodate considerable axial misalignment and even to function efficiently on slightly oval shaft geometries. This material flexibility means installation is simple and can often be performed without disassembling other unit components, minimizing downtime during maintenance routines. The 60 Shore A hardness provides an ideal balance between flexibility and stability, supporting a consistent sealing force across diverse operational conditions.
This seal is ideally suited for use in small electric motors, conveyor rollers, and similar rotating equipment. In many systems, it can serve as a protective secondary seal - extending the operational life of primary seals, especially where exposure to abrasive or hostile environments can impair sealing integrity. The wide tolerance for shaft sizes further increases application versatility, making it suitable for both original equipment and replacement use in industrial maintenance settings.
The RS PRO nitrile rubber V seal 749-626 is part of a comprehensive range of reliable sealing solutions intended for use in manufacturing, automation, assembly lines, HVAC systems, and power transmission equipment. Its compatibility with global machinery standards, robust design, and ease of use make it an essential component for engineers and maintenance professionals striving for long-lasting, leak-free performance.
