GLB Low Assembly Precision Ball Linear Guide

The GLB series low assembly precision ball linear guide features a unique four-row steel ball load-bearing structure, integrating high rigidity, heavy load capacity, and excellent self-aligning performance. Capable of absorbing mounting surface assembly errors to deliver consistent high-precision linear motion, this optimized low-profile guide rail reduces overall combination height and shortens slider length perfectly for space-constrained equipment. It is specially designed for high-speed dynamic industrial machinery and compact precision automation devices with strict dimensional and operational requirements.

Product Description

GLB Low Assembly Precision Ball Linear Guide

The GLB series uses four columns of steel balls to bear the load design, so that it has the characteristics of high rigidity and high load, and has the load cutting characteristics such as direction and automatic aligning function, which can absorb the assembly error of the mounting surface, achieve high precision, and reduce the combination height and shorten the length of the slide block, It is very suitable for high-speed dynamic industrial machinery and small equipment with space requirements.

1. Basic structure

111

2. Application

With its compact low-profile structure, high precision, high-speed dynamic performance and excellent error tolerance, the GLB low assembly precision ball linear guide is widely applied in high-precision, miniaturized and high-speed industrial equipment. It is the ideal linear motion component for modern automated production and precision manufacturing industries, with strong scene adaptability and stable operational reliability.

Its main application equipment covers handling and conveying equipment, full-set industrial automation equipment, high-precision testing instruments, food processing machinery, automated packaging machinery, medical precision equipment, as well as semiconductor and liquid crystal manufacturing and processing equipment. It fully meets the high-precision, high-speed and space-saving linear motion demands of precision manufacturing, medical hygiene, electronic semiconductor and other high-end industries.

● Preloading is recommended according to different occasion

Preload type	Application
P0（0.08—0.1C）	It is often used in situations with high ri- gidity requirements,vibration and shock
P1（0.03—0.05C）	It is often used for light vibration,light impact,bearing cantilever load and tor- sional load
P（0—0.02C）	It is often used in low-impact situations
P3（Gapped）	It is often used in occasions where the accuracy requirements are not high,the installation base surface accuracy is low,and the sliding resistance requirements are small

GLB Precision Low Assembly Ball Linear Guide Pair

Note:

1). MA, MBand MCin the table, as shown in the figure below on the right, refer to the rated static moment value of a slider.

2). LMAXin the table is the maximum length of a guide rail. For example, the length of the guide rail is to be negotiated separately (it is recommended that the guide rail be installed with holes).

3). If there is no special requirement for a single guide rail, the distance between the hole end and the two ends should be evenly divided.

4).L1 size is the standard sealing form size, check the sealing form in detail.
