RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 40 mm Inside Diameter, 56 mm Outside Diameter, 8 mm Thickness 229-9641

RS PRO 229-9641 Nitrile Rubber (NBR) Rotary Shaft Seal combines robust material and thoughtful design to deliver reliable sealing performance in industrial, hydraulic, and pneumatic applications. With dimensions specifying a 40 mm inside diameter, 56 mm outside diameter, and 8 mm thickness, this seal is tailored for precise fits in mechanical assemblies requiring effective fluid and contaminant exclusion.

Manufactured from cost-effective yet hardwearing Nitrile Rubber, the seal resists lubricant oils, hydraulic fluids, and greases while offering chemical stability against most hydrocarbons and fuels. Its double lip construction facilitates superior retention of lubricants, preventing leakage and extending the operational lifespan of the sealing interface.

The additional dust lip protects the main sealing lip from ingress of dust, dirt, and fine solid debris, making this seal ideal for use in environments exposed to pollution and contamination. This feature enhances reliability particularly in rotary shaft and hydraulic cylinder contexts where debris can impair operation.

Operating effectively within a temperature range of -20°C to 90°C, the seal covers a broad spectrum of industrial and manufacturing conditions. Its compatibility with various metric and imperial sizes allows integration into numerous machinery setups, including driveshafts and crankshafts.

Oil seals like the RS PRO 229-9641 are essential components in maintaining pressure, preventing fluid leaks, and ensuring safe, efficient operation in hydraulics, pneumatics, automotive manufacturing, power transmission, and plumbing sectors.

The seal is made from durable Nitrile Rubber (NBR) material suitable for oil and hydraulic fluid resistance. It features a double lip design ensuring optimal grease and lubricant retention, preventing dirt ingress. Includes a second dust lip providing extra protection against dust and fine contaminants.

Operates efficiently in temperatures ranging from -20°C to 90°C. Ideal for use in driveshafts, crankshafts, hydraulic cylinders, and general hydraulic and pneumatic sealing applications. Offers excellent chemical resistance to hydrocarbons, oils, and fuels.

Designed to provide long service life and maintain performance in polluted environments. Compatible with various metric and imperial sizes to suit diverse applications.
