RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 55 mm ID, 85 mm OD, 8 mm Thickness 226-3867

RS PRO 226-3867 is a high-quality Nitrile Rubber (NBR) Rotary Shaft Seal featuring a 55 mm inside diameter, 85 mm outside diameter, and 8 mm thickness. The NBR material is cost-effective and widely used in industrial mechanical and fluid power applications.

This seal is commonly applied in driveshafts, crankshafts, and hydraulic cylinders where rotating shafts require protection and lubrication retention. The NBR material offers excellent resistance to lubrication oils, hydraulic fluids, and grease, making it suitable for industrial, manufacturing, and automotive uses.

The seal operates effectively within a temperature range of -20°C to 90°C, with a hardness rating of 70 ±5 shore A, providing optimal flexibility and durability. Its tensile strength of 18.9 MPa and elongation of 438% ensure mechanical robustness under operational stress, while the tear resistance of 58 N/mm adds to its longevity in demanding environments.

Specific gravity of 1.25 ± 0.03 g/cm³ is indicative of the material density, contributing to consistent performance. The black color finish helps in easy identification and integration into assemblies.

Durable Nitrile Rubber construction ensures resistance to oils and hydraulic fluids. Designed for rotary shaft applications to maintain lubricant integrity. Wide operating temperature range from -20°C to 90°C. Hardness of 70 ±5 shore A for balanced durability.

High tensile strength and elongation for mechanical reliability. Robust tear resistance to withstand wear and tear.

This seal is ideal for use in industrial, automotive, agricultural, and hydraulic machinery applications. Choose RS PRO seals for trusted quality and performance in sealing solutions.
