GZB Series-Heavy Load Roller Linear Guide

1. Structure and Characteristic

● Structure

GZB roller heavy loading linear motion guide is consisted of rail, block,

roller, re-circulator, retainer, roller cage and seal gasket etc. (fig-1)

● Characteristic

◆ Heavy load

1、Line contact instead of traditional point contact and consequently greatly improved loading capacity with high rigidity of rollers.

2、Roller guide use V shape groove design and can bear more torque. In different applications, the distortion and stress distribution of roller rails are shown as below

3、Optimize the structure of block with finite element analysis.

◆ High rigidity

GZB roller linear guide uses the roller to replace the ball,and the contact mode between the rollers and the raceway changes from point contact to linear contact,which greatly improves the rigidity of the rolling linear guide and enables the machine to maintain higher accuracy

◆ High speed and accuracy

Roller cage prevents roller deflecting motion and moves stably. At the same time, it forms the oil film contact between roller and cage, avoid friction among rollers, reduce the heat when roller guide is running and achieve high speed and precision movement.

◆ Equal load in four directions

GZB roller heavy loading linear guide contact angle between roller and raceway is 45o, so it has equal load in four directions.

2. High pressure seal

GZB roller heavy duty linear guide pair can choose a variety of sealing forms to improve its sealing performance,especially in the high dust,more iron chips or wood chips in the environment with dustproof steel belt sealing form,the use of better.

Dust-proof steel belt:it can replace the countersink gland,make the surface of the guide rail more flat,no foreign matter will accumulate in the process of scraping,and it is easy to use and can be reused many times.

Metal scraper: Used in conjunction with the end seal, large iron filings can be scraped in advance to improve the sealing effect.

End seal: end seal and guide rail contour design, peripheral lip and guide rail interference fit to ensure a good sealing effect;

At the same time, the double-layer end seal can be selected to strengthen the sealing performance.

Note:Without DD、KK for GZB100、GZB125

4.Code rule and Definition

Roller linear guide code

Note:

If you need side refueling, please tell us.

Please use the code as below when you just need blocks or rails:

● Block cod

● Rail code

Note:

1). In the table, MA, MB and MC, as shown in the figure below on the right, refer to the rated static

moment value of a slider.

2). LMAX in the table indicates 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). For a single guide rail, if there is no special requirement, the hole distance between the two ends is equal.

4). L4 is the total size of the unmarked seal form, and the size changes of other seal forms refer to

P42 Table -1.

5). GZB series AA/AAL slide block is flange type, slide mounting hole is screw hole, lock type reference M size, lock type reference D size.

6). The GZB85, GZB100 and GZB125 sliding blocks are symmetrically distributed in 3 rows of mounting holes in the L, C and W directions on the top surface, with a total of 9 holes.

5). The GZB series BA/BAL slider is narrow and high, and the mounting hole on the top surface of

the slider is a screw hole.
