RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 32 mm ID, 52 mm OD, 7 mm Thickness 226-3791

RS PRO 226-3791 Nitrile Rubber (NBR) Rotary Shaft Seal is a high-performance sealing solution designed for industrial applications such as driveshafts, crankshafts, and hydraulic cylinders where rotating shafts are lubricated by oil or grease. It features a 32 mm inside diameter, 52 mm outside diameter, and a seal thickness of 7 mm, making it suitable for a range of mechanical and fluid power equipment.

The seal is constructed from cost-effective and widely used nitrile rubber, offering excellent resistance to lubrication oils, hydraulic fluids, and grease. NBR material is not compatible with brake oil, phosphoric ester, or ester base fluids, so selection should be application-specific.

Its operating temperature range spans from -20 degrees Celsius up to 90 degrees Celsius, making it applicable in many industrial environments. The seal hardness of 70 ±5 shore A provides durable mechanical performance, while tensile strength of 18.9 MPa and elongation at break of 438% contribute to resilience under stress and deformation.

With a specific gravity of 1.25 ± 0.03 g/cm³ and tear resistance of 58 N/mm, this rotary shaft seal maintains structural integrity during continuous operation. Typical applications include industrial machinery requiring dependable sealing against oil leaks on rotating shafts.

Constructed from nitrile rubber (NBR) for oil and grease resistance. Designed for driveshafts, crankshafts, and hydraulic cylinders with rotating shafts. Operating temperature range from -20°C to 90°C. Seal hardness 70 ±5 shore A for reliable durability.
