1.3 Integral (non separable) vertical bearing pedestal assembly with screw tight bearing housing cover. These vertical bearing block assemblies were originally developed as axle boxes for light rail trucks, but can also be used for traditional vertical bearing block assemblies. The non separable vertical bearing pedestal assembly has higher rigidity than the separable bearing pedestal, and some can withstand heavier loads. The outer spherical bearing seat also belongs to the integral type seat.

2-split bearing seat

2.1 Split bearing seats are divided into SN2, 5, 3, and 6 series according to different bearings selected and shaft requirements. SNL2, SNL5, and SD are available in 2,5,3,6,3100, 3000, and 3200

Bearing blocks are divided into: split bearing blocks, sliding bearing blocks, rolling bearing blocks, flanged bearing blocks, outer spherical bearing blocks, etc.
