High Quality Pillow Block Bearing
The housed bearing consists of a ball bearing with seals on both sides and a cast bearing seat. The internal structure of the housed bearing is the same as that of the deep groove ball bearing, but the inner ring of this kind of bearing is wider than that. The outer ring has a truncated spherical outer surface, which can be automatically aligned with the concave spherical surface of the bearing seat.
Features: Usually, there is a gap between the inner hole and the shaft of this kind of bearing, and the inner ring of the bearing is fixed on the shaft with a top wire, an eccentric sleeve or an adapter sleeve, and rotates with the shaft.
Function: The bearing with seat has compact structure, convenient loading and unloading, and perfect sealing. It is suitable for simple support and is often used in mining, metallurgy, agriculture, chemical industry, textile, printing and dyeing and conveying machinery.
According to the shape of the bearing seat
1.1 Outer spherical bearing with seat, also known as bearing unit (SKF parlance). When there is no bearing, it is called an outer spherical bearing seat. 188.8.131.52 The outer spherical bearing seat is divided into 200 series according to the series of bearings. 500 series. 300 series. 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), circular seat (C seat), boss circular seat (FC seat), convex seat Taiwan square seat (FS seat), dark hole seat (PA seat), hanging seat (FA seat).
1.3 Integral (ie, non-separable) vertical bearing housing with screw-fastened bearing housing cover. These plummer block housings were originally developed as axleboxes for light rail trucks, but can also be used with conventional plummer blocks. Non-separable plummer block housings are more rigid than separate housings, and some can handle heavier loads. The outer spherical bearing seat also belongs to the integral seat.
2.1 The split bearing seat is divided into SN2, 5, 3, and 6 series according to the different bearings and shaft requirements.
The bearing seat is divided into: split bearing seat, sliding bearing seat, rolling bearing seat, bearing seat with flange, outer spherical bearing seat, etc.
