Spherical roller bearings

タイトルまたは説明

Spherical roller bearingsare self-aligning, double-row, combination radial and thrust bearings. They use a spherical or crowned roller as the rolling element. The outer ring contains a spherical race which allows for some misalignment of the shaft and housing. To meet the most precise specifications, SRF proposes a permanently optimised Needle Roller Bearing range, providing even higher robustness.

Spherical bearingsare designed to manage high radial loads even when misalignment, poor lubrication, contamination, extreme speeds or critical application stresses are present.Spherical roller bearingsare unequalled in their capacity for high loads and tolerance to shock loads, but have limited speed capabilities. They perform consistently, even under conditions of extreme speed, application-specific stress, and marginal lubrication. The cage of a spherical roller bearing provides high dimensional accuracy and functionality. According to some estimates, spherical roller bearings have twice the running life of conventional bearings. Most spherical roller bearingsare made of alloy steels or low-carbon steels. Chrome-plated products are also available. Some applications require the use of case-hardened or thorough-hardened, high-carbon, bearing-quality steel. High-carbon grades of steel do not require carburizing and can be case-hardened by induction heating or thorough-hardened by conventional heating methods.
