QJ228-N2-MPA

Engineered for heavy axial loading in space-constrained applications, the QJ228-N2-MPA four-point contact ball bearing features a split inner ring design that accommodates a high ball complement while enabling separate mounting of the inner and outer ring assemblies. Built to standard 140x250x42 mm boundary dimensions, the QJ228-N2-MPA utilizes a 35° contact angle to support substantial thrust loads in either direction within a significantly smaller axial envelope than typical double-row setups. For smooth operational stability under high rotational speeds, the bearing is fitted with an outer-ring guided, machined solid brass cage (MPA), alongside two anti-rotation locating slots (N2) on the outer ring that prevent ring creeping inside the housing. The modular structure of the QJ228-N2-MPA further streamlines routine inspection and assembly, making it a robust solution for industrial gearboxes, compressor drives, and power transmission equipment.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
