Product Description

RS PRO 226-3872 Nitrile Rubber (NBR) Rotary Shaft Seal is an essential component for industrial mechanical systems requiring robust sealing solutions. It features a 60 mm inside diameter, a 75 mm outside diameter, and a thickness of 8 mm. This seal is engineered from cost-effective nitrile rubber known for its excellent resistance to lubrication oils, hydraulic fluids, and grease, making it suitable for use in driveshafts, crankshafts, and hydraulic cylinders where shaft rotation demands reliable sealing.

The material exhibits a hardness of 70 ±5 shore A and tensile strength of 18.9 MPa, ensuring the seal withstands mechanical wear and operational pressures. It also offers a tensile elongation of 438% and good tear resistance of 58 N/mm, supporting prolonged durability in demanding industrial conditions. The operating temperature range from -20°C to 90°C allows usage across various environmental and mechanical applications without loss of sealing integrity.

This rotary shaft seal is designed primarily for sealing applications in the mechanical, fluid power, and tool industries, including manufacturing and maintenance operations. Its black nitrile compound provides a balance between flexibility and toughness, though it is not suitable for brake oils, phosphoric esters, or ester-based fluids, ensuring proper application selection is essential.

Durable nitrile rubber material resistant to common lubricants and hydraulic fluids. Precise dimensions for effective sealing: 60 mm ID, 75 mm OD, and 8 mm thickness. Suitable for rotary shaft applications in driveshafts, crankshafts, and hydraulic cylinders.

Temperature operating range from -20°C up to 90°C for versatile use. Material specifications include 70 ±5 shore A hardness and 18.9 MPa tensile strength. High elongation and tear resistance improve longevity under stress.

Widely used across industrial mechanical, fluid power, and manufacturing sectors.
