How to classify according to the shape of the bearing seat

The outer spherical bearing seat is divided into vertical seat (P seat), square seat (F seat), prismatic seat (FL seat), circular seat (C seat), convex circular seat (FC seat), convex square seat (FS seat), concealed hole seat (PA seat), and hanging seat (FA seat) according to the shape.

Integral (non separable) vertical bearing pedestal assembly with screw tight bearing housing cover. This vertical bearing block assembly was originally developed and designed as a axle box for light rail freight cars, but it can also be used as a traditional vertical bearing block assembly. Non separable vertical bearing block assemblies have higher stiffness than separable bearing blocks, and some can withstand heavier loads. The outer spherical bearing seat also belongs to the integral seat.

Split bearing seat

Split bearing seats are divided into SN2, 5, 3, and 6 series according to the different bearings selected and their shaft regulations. 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.
