    Crossed Roller Slide Table Introduction

    ♦   Crossed Roller Slide Table

    Table is composed of GMT crossed roller type slide rail set, V-grooved, crossed rollers matched with assembly plane in hign accuracy processing, and base; installed with limit mechanism between two ends of table, is small type of limit stroke linear motion product in high rigidity. Performance as high accuracy and low friction, apply to electric parts used in automatic installation equipment and optical gauge. 

    ♦   Slide Table Unit Selection Procedure

    1. Select unit width and length.
    2. Select model per installation.
    3. Acquire model no. from catalogs.
    4. Select standard, antirust or corrosion-resisting per environment request.

    ♦   Slide Table Property

    • High Accuracy:In order to perform function of GMT Slide Table entirely, all assembly planes of table and base are processed in precise grinding to get linear motion in high accuracy. 
    • Low Friction:Low friction because of non-circulation. Stable performance in whether low speed or high speed. 
    • High Rigiditym, Space Saving:Besides high load capacity and high rigidity of roller guide in GMT linear motion table, space saving design is also considered at same time. 
    • No Demand of Adjustment:Accuracy and preload would be matched perfectly to use directly without heavy adjustment. 
    • Easy Installation:Standardized assembly holes of unit and base are easy to lock and secure with screw only to have linear motion in high accuracy.
