Four-point bearings - Import export

Are you operating an application requiring a bearing arrangement with high load carrying capacity with low-noise operation? Our durable four-point bearings are the perfect solution for this scenario and can support high axial loads as well as radial forces (relatively lower) in both directions. Four-point bearings are similar in structure to double-row angular contact ball bearings, but are much narrower in the axial direction due to a single raceway. The circular arc-shaped raceways in the inner and outer ring have opposite centres of curvature so that the balls contact the races at four points under radial load. If there is a predominantly radial load, four-point bearings should be avoided due to the higher friction in four-point contact. In assembly, one of the two races, often the inner race, is split to insert the balls. Since four-point contact bearings are often installed radially exposed, the outer rings can optionally be equipped with retaining grooves to prevent rotation.
