SKF deep groove ball 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.
SKF 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.
Low-friction seals are available for bearings in the 60, 62 and 63 series. They are manufactured in two designs depending on bearing size.
