      Release:rhqqzmkm Browse:28

        The meaning of bearing housing

        Since one bearing can choose different bearing housings, and one bearing housing can choose different types of bearings at the same time, there are many varieties of bearing housings. Bearing housings are included in Quick, Easy and Excellent, and many large foreign bearing companies also have their own housing catalogs. However, the markings of the same bearing housing model in different company samples are not exactly the same. For different applications of standard housings, housings of different materials can be selected, such as special housings made of gray cast iron, ductile iron, cast steel, stainless steel, and plastic.

        Bearing housing-overview

        According to the different requirements of the bearing and the bearing housing, the classification of the bearing housing is not exactly the same. When using it, carefully check the selection according to the design.

        1 Classified according to the shape of the bearing housing:

        1.1 The outer spherical housinged bearing, also called the bearing unit (SKF parlance). When there is no bearing, it is called an outer spherical bearing housing. The outer spherical bearing housing is divided into 200 series according to the bearing series. 500 series. 300 series. 600 series. XOO series.

        1.2 The outer spherical bearing housing is divided into vertical housing (P housing), square housing (F housing), diamond housing (FL housing), round housing (C housing), boss round housing (FC housing), convex Table square housing (FS housing), dark hole housing (PA housing), hanging housing (FA housing).

        1.3 Integral (that is, non-separable) vertical bearing housing assembly, with screw-fastened bearing box cover. These vertical bearing block sets were developed as axle boxes for light rail trucks, but they can also be used in traditional vertical bearing block sets. Non-separable vertical bearing housing assemblies are more rigid than separate bearing housings, and some can withstand heavier loads. The outer spherical bearing housing is also an integral housing.

        2 Split housing

        2.1 Split bearing housing, according to the different bearings selected and the shaft requirements, divided into SN2, 5, 3, 6 series, SNL2, SNL5, SD have 2, 5, 3, 6, 3100, 3000, 3200

        The bearing housing is divided into: split bearing housing, sliding bearing housing, rolling bearing housing, bearing housing with flange, outer spherical bearing housing, etc.
