SKF low-friction Waveseal shaft-sealing solutions feature a molded lip to form a sinusoidal or wave pattern around the shaft surface, improving lubricant retention while pushing dirt away from the surface to protect against contamination. According to the company, the lip generates 25 to 35% less heat at the contact point, minimizing premature seal failure from heat checking, blistering, hardening, or lubricant breakdown. Other benefits include reduced friction torque or drag, curbed shaft wear, and improved lip lubrication. The Waveseal series fit shaft diameters from 0.25 to 12.25 in (6 to 310 mm). Suitable applications include gearboxes, speed reducers, transmissions, motors, drive systems, and pumps; customized sealing solutions are available.
