Types RSL and RSH Seals

Types RSL and RSH seals provide greater sealing efficiencies due to a combination of seal lip and additional labyrinth formed by a gap between the tapered rubber part and the inner ring shoulder. Use of uniquely shaped sheet steel reinforces the rubber material, which keeps the seal stiff within the lean design. High-precision manufacture of seal counterfaces and specially engineered recesses in inner ring shoulders help to reduce seal lip wear. These nitrile rubber, low-friction seals promote lower energy consumption, offer superior grease retention, and contribute to longer bearing service life. RSL and RSH seals are available for deep-groove ball bearings with bore diameters ranging from 6 mm to 25 mm and with maximum outside diameters of 52 mm. SKF USA Inc.
