Description

Each shaft sealing ring in this set is equipped with three lips, a design that effectively balances sealing pressure. This balanced pressure reduces friction and operating temperature, leading to less wear and improved breakaway torque compared to standard seals. The key benefit of this advanced design is an extended service life, stated to be 3-4 times longer than Original Equipment (OE) simmerrings. The specific dimensions of these seals are 37mm inner diameter, 49mm outer diameter, and 8/9.5mm for the installation height/total height. This kit is manufactured in Taiwan (TW).
