What are the types of outer spherical bearings?
What are the types of outer spherical bearings? I believe we all know that there are many kinds of spherical bearings, but how many kinds are there? First of all, according to a shape, which is the most direct simple: spherical bearings are roller bearings and bearing seats together in a bearing unit. Most of the outer spherical bearings are made of outer diameter spherical surface, and with a spherical bore of the bearing seat together, the structure of various forms, versatility and interchangeability good. At the same time, such bearings in the design also has a certain mind, easy to install, with double structure of the sealing device, can work in a harsh environment. Bearing housings are generally made of cast iron. Commonly used seats are vertical block (P), square block (F), lug, square block (FS), convex table, round seat (FC), diamond seat (FL), ring block (C), block block and so on (T).
Types of outer spherical bearings
Spherical bearings for heart bearing and bearing seat, based on the name for bearing with bearing seat call center, such as the set screws with spherical bearing UC205 with vertical block UCP205. Spherical bearings with a strong interchangeability, bearing heart can be assembled on the same specifications bearing in different shapes.
According to the shape can be divided into: seat belt vertical outer spherical ball bearing (http://www.hstaibang.cn/s/lishi/), with a square base bearing (http://www.hstaibang.cn/s/fangxing/), with a diamond shaped outer spherical ball bearing (http://www.hstaibang.cn/s/lingxing/), with the convex platform round a spherical ball bearing, annular seat outer spherical ball bearing, spherical ball bearings, belt suspension type slide seat outer spherical ball bearing, seat belt suspension type spherical ball bearing, with adjustable diamond seat insert ball bearings, with stamping seat outer spherical ball bearing, spherical ball bearing seat on the other.
And then the spherical surface ball bearings, in accordance with the axis of cooperation, can be divided into three major categories:
Outer spherical ball bearing with top wire
First, with the top wire outer spherical ball bearing the symbol: UC200 series (light series), UC300 series (heavy duty Series), product UB and deformation (SB) 200 series, if using the environment fit smaller, usually select UC200 series, UC300 series and selection. The top wire usually spherical ball bearing on the is two, the angle is 120 degrees, is the character of cooperation and shaft with screw top is on the shaft, and then play the fixed effect, but the cooperation environment needs to have the necessary small oscillation. This kind of spherical surface ball bearings is widely used in textile machinery, ceramic machinery and other production occupations.
External spherical bearing with taper
Two, with taper outer spherical ball bearing, its code name is: UK200 series, UK300 series. The outer spherical ball bearing inside diameter of 1:12 share of the taper hole, and the sleeve using this kind of cooperation, the outer spherical bearing features: able to accept than with the top wire load of outer spherical ball bearing more. Because of their cooperation with the sleeve type inner diameter than the outer spherical ball bearing screw with small, for example, with the top wire outer spherical ball bearing UC209 inner diameter is 45mm, and the diameter of the shaft for cooperation with 45mm, and if if replaced with taper ball bearings, can only choose 45mm diameter sleeve, tapered outer spherical ball bearing and sleeve tight cooperation with 45mm is UK210 (of course, if fit better. Can choose UK310). As a result, UK210's acceptance fits much better than UC209's..
With eccentric sleeve outer spherical bearing three, with eccentric sleeve outer spherical ball bearing (http://www.hstaibang.cn/s/pianxintao/), its code name is: UEL200 series, UEL300 series, SA200 series. The outer spherical ball bearing primary characteristics for bearing on one end of a certain degree of eccentric, have the same degree of eccentric eccentric set of its cooperation. This bearing also can be said to be due to its special bearing, mainly in agricultural machinery (harvester, straw machine, threshing machine etc.) on the use of this kind of ball bearings used in the first match beating strong layout, eccentric layout cooperation can be useful to cut the strong beat.
The above is a detailed description of the types of spherical bearings, and we hope to help. There are many kinds of spherical bearings, but we also need to observe and see which is suitable for ourselves.
