SKF QJ 213 MA C3 Four Point Contact Ball Bearing

SKF QJ 213 MA C3 is a four-point contact ball bearing engineered to support combined radial and axial loads with stiffness and precision in compact assemblies. The C3 suffix denotes greater than normal radial clearance, a characteristic that affects running clearance and accommodates shaft expansion or modest misalignment under operating conditions. In the four-point contact design, each ball engages both raceways at four points, enabling load sharing between radial and thrust components and providing stability when axial thrust loads are present in either direction. Four-point contact bearings are commonly chosen when a single bearing must carry both radial loads and thrust in two directions, reducing the need for coaxial thrust bearings and enabling a shorter, stiffer support in assemblies. With SKF's QJ family and this model's clearance class, the bearing offers a balanced combination of load capacity, rigidity, and operating clearance suitable for compact precision applications.
