The FP 28x38x5/8 RM NBR Oil Seal is engineered for rotating equipment requiring dependable sealing performance in compact installation spaces. It is widely used in industrial pumps, electric motors, gearboxes, hydraulic systems, compressors, agricultural machinery, and OEM equipment where efficient lubricant retention and reliable operation are essential.

The RM Profile features a rubber-covered metal case combined with a spring-loaded primary sealing lip. The rubber-covered outer diameter improves sealing between the oil seal and housing while compensating for minor bore imperfections, ensuring a secure fit and minimizing leakage around the outside diameter.

An integrated garter spring continuously maintains radial sealing force against the rotating shaft, effectively preventing lubricant leakage while protecting bearings, shafts, and internal components from premature wear.

Manufactured from premium NBR (Nitrile Butadiene Rubber), this seal provides excellent resistance to:

• Mineral oils
• Hydraulic oils
• Gear oils
• Lubricating grease
• Petroleum-based lubricants

NBR offers excellent abrasion resistance, elasticity, and long-term durability for general industrial applications. Typical operating capability is up to 0.5 Bar, with operating temperatures ranging from -40°C to +100°C, depending on shaft speed, lubrication, and operating conditions.

With dimensions of 28 × 38 × 5/8 mm, this oil seal is commonly installed in electric motors, industrial pumps, speed reducers, hydraulic equipment, compressors, conveyor systems, agricultural machinery, and OEM rotating machinery.
