What’s the difference between slide block bearing and linear bearing?

From the cost point of view: the same brand, linear guides are more expensive than linear bearings;
From the equipment point of view: linear guides have higher accuracy than linear bearings, greater load, strong stability and longer life;
From the market point of view: slide block bearing have a wider range of applications than linear bearings, and linear bearings are relatively only suitable for preliminary processing;

Linear Bearings:
Linear bearing is a kind of linear motion system, used for linear stroke and cylindrical shaft. Because the bearing ball is in point contact with the bearing jacket, the steel ball rolls with the least frictional resistance. Therefore, the linear bearing has low friction, is relatively stable, does not change with the bearing speed, and can achieve high sensitivity and high smooth linear motion. The consumption of linear bearings also has its limitations. The most important thing is that the impact load capacity of the bearing is poor, and the load capacity is also poor. Secondly, the linear bearing has greater vibration and noise during high-speed motion. Linear bearings are widely used in sliding parts of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery.

Linear slide block bearing:
The function of slide block bearing is to support and guide the moving parts to make reciprocating linear motion in the specified direction. According to the nature of friction, slide block bearing can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. slide block bearing are mainly used in mechanical structures that require relatively high precision. There is no intermediate medium between the moving and fixed elements of the slide block bearing, but rolling steel balls.

Scope of application of slide block bearing:
HG series: grinders, milling machines, lathes, drilling machines, integrated processing machines, electrical discharge machines, boring machines, wire cutting machines, precision measuring instruments, woodworking machines, handling machines, and conveying devices.
EG series: industrial automation machines, semiconductor machines, laser engraving machines, packaging machines.
MGN/MGW series: printers, robotic arms, electronic equipment, semiconductor equipment.
RG series: CNC processing machine, heavy chip processing machine, CNC grinder, injection molding machine, electric discharge machine, wire cutting machine, large gantry machine tool.
Q1 series: suitable for high-speed, quiet and low-dust electronic industries.
