SKF Single row deep groove ball bearing with two low friction rubber seals 20mm inside x 42mm outside x 12mm width
SKF Low friction Single row deep groove ball bearings are used in a wide variety of applications, they are simple in design, non-separable, suitable for high speeds and are robust in operation, and need little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads.
Low friction deep groove ball bearings from SKF facilitate the 30% plus friction reduction. These bearings are equipped with low friction seals, a low friction grease and a special cage.
Bearings with low-friction seals can accommodate the same speeds as bearings with shields, but with improved sealing effectiveness. The seals are practically non-contacting with a recess in the inner ring shoulder.
Single row deep groove ball bearings with a low-friction seal on one or both sides are identified by the designation suffix RSL or 2RSL. The seals are made of oil and wear-resistant NBR that is reinforced with a sheet steel insert.
