Full Size Nitrile Rubber Sealing High Temperature Oil Seal Ring Skeleton Oil Seal
Product
The outer layer is an iron shell, designed for steel rotating shafts or cast iron pool holes.
Exceptional wear resistance for high-speed, high-frequency applications: SB type oil seals are made from high-quality, highly elastic materials such as nitrile rubber (NBR) and fluorocarbon rubber (FKM), combined with advanced vulcanization processes, to provide outstanding wear resistance. In high-speed rotating applications (maximum speed up to 3000 rpm) such as motor shafts, gearbox input shafts, and high-frequency vibrating compressor crankshafts, wear rates are reduced by 30% compared to standard oil seals, significantly extending the replacement cycle and minimizing equipment downtime for maintenance.
The temperature resistance range is extremely broad: NBR material can operate stably at temperatures ranging from -40°C to +120°C, meeting the requirements of conventional industrial environments; FKM material can withstand extreme temperature differences from -26°C to +250°C. Whether in outdoor equipment in cold regions or in high-temperature, high-pressure engine compartments, SB-type oil seals maintain excellent elasticity and sealing performance, ensuring stable operation of equipment under all conditions and in all environments.
