McGill SB series SPHERE-ROL® bearings present all of the inherent advantages of a single row spherical roller bearing, plus the option of integral seals. Higher capacities, higher limiting speeds, longer life under more misalignment and protection from contaminants permit greater design latitude than is sometimes possible with comparable 2-row spherical roller bearings. McGill SPHERE-ROL® bearings are dimensionally interchangeable with ordinary 2-row spherical roller bearings. However, they offer the design engineer a more efficient bearing design that helps provideimproved performance. A single row of large rollers results in increased dynamic load capacity. It also results in up to 100% greater misalignment of conventional double-row spherical roller bearings.
SPHERE-ROL® Bearings are available in two standard series: 22200 series - 20 to 150 mm bore sizes 22300 series - 40 to 100 mm bore sizes
Potential extended bearing life as a result of three different sealing options available:
NYLAPLATE® seal - Combination labyrinth / contact seal with low running friction
NYLAPLATE high temp seal - High temperature material combination labyrinth / contact seal for high temperature applications or where chemicals may be present
