The TROSTEL 3.500x4.506x0.469 SYN NBR Oil Seal is a premium industrial rotary shaft seal engineered to prevent lubricant leakage while protecting critical rotating components from dust, dirt, moisture, and external contaminants.

The SYN (Synthetic NBR) sealing compound delivers excellent resistance to mineral oils, grease, hydraulic fluids, and common industrial lubricants. This material maintains flexibility and sealing efficiency throughout continuous operation, making it suitable for demanding industrial environments.

Designed for heavy-duty service, the seal provides reliable shaft sealing performance in applications exposed to vibration, load fluctuations, and extended operating cycles. The robust construction helps maintain sealing integrity while extending equipment life and reducing maintenance requirements.

The 3.500 x 4.506 x 0.469 inch size is commonly found in industrial gearboxes, conveyors, hydraulic systems, agricultural machinery, mining equipment, and imported machinery utilizing inch-size shaft dimensions.
