Pllow Blocks Bearings UC208

According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same, and it is necessary to carefully check the selection according to the design when using.

1 Classification according to the shape of the bearing seat:

1.1 Outer spherical bearing with seat, also known as bearing unit (SKF). When there is no bearing, it is called the outer spherical bearing seat. 1.1.1.1 The outer spherical bearing seat is divided into 200 series according to the bearing series. The 500 series. The 300 Series. The 600 Series. XOO series.

1.2 The outer spherical bearing seat is divided into vertical seat (P seat), square seat (F seat), diamond seat (FL seat), round seat (C seat), convex round seat (FC seat), convex square seat (FS seat), dark hole seat (PA seat), hanging seat (FA seat) according to its shape.

1.3 Integral (i.e., non-separate) vertical bearing housing group with screw-secured bearing box cover. These vertical housing sets were originally developed as axle boxes for light rail trucks, but can also be used with conventional vertical housing sets. Non-separated vertical housings are more rigid than separated housings, and some can withstand heavier loads. The outer spherical bearing seat also belongs to the integral seat.

2 split bearing seat

2.1 Split bearing seat, divided into SN2, 5, 3, 6 series according to the different bearing options and shaft requirements, SNL2, SNL5, SD have 2, 5, 3, 6, 3100, 3000, 3200[1]

Bearing seat is divided into: split bearing seat, sliding bearing seat, rolling bearing seat, bearing seat with flange, outer spherical bearing seat, etc.
