The meaning of bearing seat
Since a bearing can use different bearing seats, and a bearing seat can use different types of bearings at the same time, there are many varieties of bearing seats. Bearing seat quick and easy to include, and many large foreign bearing companies also have their own bearing seat catalogs. However, the same bearing seat model is not exactly the same in the catalogs of different companies. For different applications of standard bearing seats, you can choose bearing seats made of different materials, such as: gray cast iron, ductile iron and cast steel, stainless steel, and special bearing seats of plastic.
Bearing seat - Overview
According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same. When using, you must check and select carefully according to the design.
1 Classification by the shape of the bearing seat:
1.1 Spherical bearing with seat, also known as bearing unit (SKF's statement). When there is no bearing, it is called an outer spherical bearing seat. 1.1.1.1 Spherical bearing seat is divided into 200 series according to the series of bearings. 500 series. 300 series. 600 series. XOO series.
1.2 Spherical bearing seats are divided into vertical seats (P seats), square seats (F seats), diamond seats (FL seats), round seats (C seats), boss round seats (FC seats), boss square seats (FS seats), blind hole seats (PA seats), hanging seats (FA seats) according to their shapes.
1.3 Integral (i.e. non-separable) vertical bearing seat assemblies with screw-fastened bearing box covers. These vertical bearing seat assemblies were originally developed as axle boxes for light rail trucks, but can also be used in traditional vertical bearing seat assemblies. Non-separable vertical bearing seat assemblies are more rigid than separable bearing seats, and some can withstand heavier loads. Spherical bearing seats are also integral seats.
2 Split bearing seat
2.1 Split bearing seat, according to the different selected bearings and shaft requirements, divided into SN2, 5, 3, 6 series, SNL2, SNL5, SD have 2, 5, 3, 6, 3100, 3000, 3200
Bearing seat is divided into: split bearing seat, sliding bearing seat, rolling bearing seat, bearing seat with flange, outer spherical bearing seat, etc.
