Classification of Insert Bearing
Insert bearing in accordance with the axis of cooperation methods to be divided into three categories can be divided into:
A, with a top wire outer spherical ball bearing the code: uc200 series (light series), a series of UC300 (heavy duty Series) and deformation of product of Ub (sb) 200 series, if use environment fit smaller, usually select uc200 series. Conversely, selection of UC300. Usually outer spherical ball bearing on the top of the wire are two, the angle is 120 degrees. Its characteristics is with co axial is with the top of the wire to get to the top of the shaft, and then play a fixed effect, but environmental needs the cooperation of a small scale oscillations necessary. The outer spherical ball bearings are widely used in textile machinery, ceramic machinery and other production occupations.
Two, with taper outer spherical ball bearing its code name: UK200 series, UK300 series. Such outer spherical ball bearing diameter of 1: 12 share the taper hole, use with tight set set of cooperation with, the characteristics of this kind of outer spherical ball bearing is able to accept than with a top wire outer spherical ball bearing a greater load. Due to the work with the locking set the same type of inner diameter than with a top wire outer spherical ball bearing small, for example with a top wire outer spherical ball bearing UC209 diameter of 45mm, and phase cooperation with the diameter of the shaft is 45mm, and if if replaced with taper outer spherical ball bearing, can only choose diameter 45mm tight sets, and 45mm tight set for cooperation with taper outer spherical ball bearing only UK210 the (of course, if fit higher can choose UK310). As a result, the acceptance of the UK210 fit when so much bigger than the UC209.
Three, with eccentric spherical ball bearing its name: UEL200 series, UEL300 series, SA200 series. This kind of outer spherical ball bearing primary characteristics on one end of the bearing has certain eccentric degree, have the same eccentric eccentric sleeve and cooperation. Such bearings can also say is special bearings due to the primary is used in agricultural (harvesting machine, straw returning machine, threshing machine, etc.), such outer spherical ball bearing is mainly used to beat match strong layout, eccentric layout of cooperation can be useful cuts a strong beat.
