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.

SKF spherical roller thrust bearings
The SKF spherical roller thrust bearings are engineered to accommodate heavy axial and simultaneous radial loads in high-speed industrial equipment applications. Their self-aligning capability further allows these bearings to compensate for shaft deflection and misalignment without reducing bearing service life. Applications include large vertical electric motors, gearboxes, pumps, fans, crushers, machine tools, injection molding equipment, and other machinery performing at relatively high speeds and with combined loads. These bearings incorporate asymmetrical rollers and specially designed raceways offering optimum conformity. Cages are made from steel or optional machined brass (for larger bearing sizes). Bore sizes range in diameter from 60 mm to 1,250 mm (2.3622 in to 49.2126 in.) and boundary dimensions conform to ISO 104-2002 standards.
