The HUMPHREY Oil Seal 2.0625x3.005x0.4375 RG NBR is engineered for rotating shaft applications requiring dependable sealing performance and protection against lubricant leakage.

The RG profile is a rotary shaft seal design commonly used in industrial machinery and power transmission equipment. The seal is designed to retain oil and grease within the system while preventing dust, dirt, and moisture from entering the bearing or gearbox housing. RG-type seals are widely applied in non-pressurized systems and are valued for their low-friction sealing characteristics.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing element provides excellent resistance to mineral oils, lubricating grease, hydraulic fluids, and petroleum-based lubricants. NBR remains the most widely used sealing material in industrial oil seals due to its excellent balance of oil resistance, durability, flexibility, and cost-effectiveness.

With dimensions of 2.0625 x 3.005 x 0.4375 inch, this seal is commonly used in industrial gearboxes, pumps, electric motors, speed reducers, agricultural equipment, conveyors, and imported machinery utilizing inch-size shaft systems.
