RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 45 mm Inside Diameter, 58 mm Outside Diameter, 7 mm Thickness 226-3827

RS PRO 226-3827 is a high-quality nitrile rubber (NBR) rotary shaft seal designed to provide reliable sealing performance in industrial and mechanical environments. This seal features a 45 mm inside diameter, 58 mm outside diameter, and a thickness of 7 mm, making it ideal for use in driveshafts, crankshafts, and hydraulic cylinders where rotating shafts require protection and lubrication retention.

Manufactured from nitrile rubber, the seal offers excellent resistance to various lubrication oils, hydraulic fluids, and grease, ensuring longevity and effective sealing under typical operating conditions. This material provides a hardness of 70 ±5 Shore A, a tensile strength of 18.9 MPa, and an elongation rate of 438%, which combine to deliver a robust and flexible sealing solution. The tear resistance rating of 58 N/mm further enhances its durability against mechanical stresses encountered during rotational shaft movements.

The operating temperature range between -20°C and 90°C makes this seal adaptable for many industrial applications, though it is not suitable for brake oils or phosphoric ester-based fluids. The seal’s specific gravity is 1.25 ± 0.03 g/cm³, balancing material density for effective performance.

This RS PRO seal is available in black color and is supplied in bags containing 5 seals, offering convenience for maintenance and replacement tasks in industrial, automotive, agricultural, and manufacturing settings. Its applications span fluid power systems, hydraulic equipment, and mechanical shafts that demand oil or grease retention while preventing contamination ingress.
