High-temperature oil seals for construction machinery REXROTH hydraulics are specially developed for hydraulic applications exposed to elevated operating temperatures and heavy-duty workloads. Produced from high-performance sealing materials such as FKM or specially formulated NBR, these seals provide excellent resistance to heat, hydraulic oil, pressure, friction, and aging. They help prevent leakage, maintain sealing integrity, and protect hydraulic components from contamination in harsh construction and industrial environments.

Suitable for hydraulic pumps, motors, cylinders, and valve assemblies used in excavators, loaders, bulldozers, and road construction equipment, these seals are designed for stable performance under thermal stress and continuous operation. Their optimized lip design offers dependable shaft contact, reduced wear, low friction, and extended service life. Ideal for replacement parts supply, maintenance service, and industrial application support, they help reduce downtime and improve machine reliability. These high-temperature oil seals are an effective sealing solution for REXROTH hydraulic systems working in high-heat construction machinery conditions.
