The bearing seat introduces a large and extra large bearing seat that can accept the comprehensive load and special construction. The bearing seat has the characteristics of compact structure, sensitive rotation, and convenient device maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is a shaft, and the outer support is often referred to as a bearing seat.
Bearing housing meaning
Because one bearing can use different bearing seats, and one bearing seat can also use different types of bearings at the same time, therefore, there are many varieties of bearing seats. Bearings are readily available, and many large foreign bearing companies also have their own bearing housing catalogs. However, the same bearing type is not identical in the different company samples. For different applications of standard bearing housings, different material bearing housings can be selected such as gray cast iron, ductile iron and cast steel, stainless steel, plastic special bearing.

ball bearing housing - Overview
According to the different requirements of the bearing and the bearing seat, the classification of the bearing seat is not completely the same. When using it, it must be carefully checked according to the design.
1 According to the shape of ball bearing housing seat:
1.1 Spherical bearing, also known as the bearing unit (SKF's statement). When not bearing, it is called spherical bearing. 1.1.1.1 Outer spherical bearing housing It is divided into 200 series according to the bearing series. 500 series. 300 series. 600 series. XOO series.
1.2 Spherical bearing housings are divided into vertical seats (P seats), square seats (F seats), diamond seats (FL seats), round seats (C seats), and bosses round seats (FC seats). Taiwan square seat (FS seat), dark hole seat (PA seat), hanging seat (FA seat).
1.3 Integral (ie, non-separated) vertical bearing housings, bearing housing caps with screws. These vertical bearing housings were originally developed as axle boxes for light rail trucks, but they can also be used with conventional vertical bearing housings. Non-separable vertical bearing housings are more rigid than split bearing housings and some can withstand heavier loads. Spherical bearing housings also belong to integral seats.

2.1 Split bearing seat, according to the different bearings and shaft requirements SN2, 5, 3, 6 series, SNL2, SNL5, SD 2,5,3,6,3100,3000,3200
Bearing seats are divided into: split bearing blocks, sliding bearing blocks, rolling bearing blocks, flanged bearing blocks, spherical bearing blocks and the like.
Wear problem
Wear is the most common problem in bearing housings, and bearing seat wear often occurs.
Repair method
Conventional methods generally use surfacing machining to repair, and surfacing will cause the surface of the component to reach a very high temperature, resulting in deformation or cracking of the component. The size obtained through machining will cause a significant increase in downtime. The use of polymer composites for on-site repairs has no thermal effects, and the repair thickness is not limited. The wear resistance of the products and the concessions that are not possessed by the metal materials ensure that the repair site is 100% contact-fitted and the equipment is reduced. The impact of vibration, to avoid the possibility of wear. Repair on site to avoid machining methods.
