Joint bearings is a mechanical component used to fix two parts, and its spherical sliding structure has the function of allowing relative displacement of two parts.
Couplings, a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque.
There are many types of linear modules, and there are quite a lot of dimensions. For example, according to whether they are sealed or not, they can be divided into sealed and dust-proof linear modules and semi-closed linear modules.
Linear modules are also called linear modules, Cartesian coordinate robots, and linear slides. According to the drive mode, it can be divided into three categories: belt type, ball screw and linear motor, but the basic working principle is the same.

Linear guides are used to support and guide moving parts for linear reciprocating motion, which can achieve high-precision linear motion under high load conditions, and have a higher rated load than linear bearings.
Linear guides can be divided into: roller linear guides, cylindrical linear guides, and ball linear guides, which are used to support and guide moving parts and perform reciprocating linear motion in a given direction. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types.
The function of the linear guide is to support and guide the moving parts to perform reciprocating linear motion in a given direction. In order to use the right type of linear guide for the right occasion, it is necessary for the design engineer to understand the advantages and capabilities of different guides, so as to make a reasonable choice.
Ball linear guide is a kind of linear guide with rolling parts as balls. It has the characteristics of strong load capacity, high precision, long service life, high rigidity and relatively high maintenance cost.
When using linear guide rails, some friends who are new to this kind of linear guide rails may find a strange phenomenon, that is, the guide rail sliders are locked, and the situation is still unclear for a while. Let me introduce the linear guide rail sliders. Six principles of locking: locking screw locking, cylinder clamping, clamper, locking slider, with self-locking function and guide rail is damaged.
Committed to provide quality linear bearing and linear guide products that meet all your needs.
