RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 35 mm ID, 55 mm OD, 8 mm Thickness 226-3800

RS PRO 226-3800 nitrile rubber (NBR) rotary shaft seal offers an effective sealing solution for industrial, mechanical, and fluid power applications. Made from high-quality nitrile rubber, this seal is the most commonly available and cost-effective option for use in lubricated rotating shafts such as in driveshafts, crankshafts, and hydraulic cylinders.

The seal's material provides excellent resistance to lubrication oils, hydraulic fluids, and grease, ensuring long service life and reliable performance in harsh environments. However, it is not suitable for brake oils or ester-based fluids.

Its dimensions are precisely engineered at 35 mm inside diameter, 55 mm outside diameter, and 8 mm thickness to fit typical rotary shaft assemblies requiring robust sealing. The operating temperature range from -20°C to 90°C accommodates many industrial settings while the 70 ±5 shore A hardness provides durability against wear and deformation.

Additional mechanical properties include a tensile strength of 18.9 MPa, elongation capability of 438%, specific gravity near 1.25 g/cm³, and tear resistance rated at 58 N/mm, supporting structural integrity during machine operation.

Constructed from cost-effective nitrile rubber (NBR) material. Suitable for driveshafts, crankshafts, and hydraulic cylinders with rotating shafts. Resistant to lubrication oils, hydraulic fluids, and grease. Measures 35 mm inside diameter and 55 mm outside diameter with 8 mm thickness.

Operates reliably within a temperature range of -20°C to 90°C. Exhibits hardness of 70 ±5 shore A for durability. Features tensile strength of 18.9 MPa and elongation at 438% for flexibility. Specific gravity approximately 1.25 ± 0.03 g/cm³ with tear resistance of 58 N/mm.

This seal is ideal for industrial machinery maintenance, construction equipment, automotive repair, hydraulic systems, and manufacturing operations. Ensure compatibility with your application fluid types before use.
