The TROSTEL Oil Seal 4.250x5.375x0.500 LGS NBR is engineered for industrial applications requiring dependable sealing performance under continuous operation and challenging environmental conditions.

The LGS (Loaded Garter Spring) design incorporates a precision spring-loaded sealing lip that maintains constant contact pressure against the shaft surface. This helps improve lubricant retention while preventing dust, moisture, and contaminants from entering the equipment.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to mineral oils, grease, hydraulic fluids, and common industrial lubricants. NBR remains one of the most widely used sealing materials because of its balance of durability, flexibility, and cost-effectiveness.

The heavy-duty construction makes this seal suitable for industrial gearboxes, pumps, electric motors, conveyors, mining equipment, agricultural machinery, and imported industrial equipment operating in demanding environments.

TROSTEL has long been recognized as a manufacturer of industrial sealing products and shaft seal solutions for industrial applications.
