Linear bearing seals: Types, options, and appliions

Dec 15, 2020· Low-friction seals are also used in appliions where seal drag (friction due to the bearing seals) should be minimized to meet appliion requirements, such as low running torque or force. Keep in mind that the more contact the seal makes with the running surface, the more force is required to overcome the seal friction.

On the Friction of Oil-Impregnated Sintered Bearings

Nov 12, 2018· Oil-impregnated sintered bearings are widely used in various products. Friction reduction in them is still a large target for the related industries. In those bearings, lubriing oil exudes from the porous bearing body and lubries the shaft and bearing surfaces. However, the amount of oil in those sliding areas is often insufficient leading to an unsatisfactory friction.
