The QJ 1060 MPA Four-point contact ball bearings are widely used in equipment requiring space and complex load-bearing capacity, such as industrial robots (wrist joints), machine tools (rotary tables), medical equipment (CT scanner rotating frames), radar antennas, solar tracking systems, and lifting machinery.

The QJ 1060 MPA bearing is a Four point contact bearings with an inner diameter of 300 mm , an outer diameter of 460 mm, a width of 74 mm. It typically uses PN (ABEC-1) grade precision tolerances and GCr15SiMn rings, GCr15SiMn rolling mlement. Its dynamic radial rated load is approximately 628872 N, its static radial rated load is approximately 1249568 N. It uses CN standard radial clearance, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The QJ 1060 MPA Four-point contact ball bearings primarily consist of an inner ring (usually a double-half inner ring or an integral one), an outer ring, steel balls, and a cage. The raceways are Gothic arched, and the steel balls form four-point contact with the inner and outer rings. Gears can be integrated into the inner and outer rings, resulting in a compact structure.

A single set of four-point contact ball bearings can simultaneously withstand radial loads, bidirectional axial loads, and overturning moments, eliminating the need for paired installation. They feature low axial height and light weight, saving installation space. They possess high rigidity and low friction characteristics, making them suitable for light to medium load conditions.
