Precision cross roller guide VR12 roller linear slide VR12

CAGE GUIDEWAYS WITH LIMITED STROKE

The cage guideways can be equipped with ROLLERS or BALLS or NEEDLES and are suitable for many applications in the medium to high requirement range. These products have limited stroke and provide rigid yet supple linear motion and are particularly suitable for linear guidance where high rigidity and supple movement are demanded.

-Cross Roller Guide Model VR / Type R
VR Model Cross Roller Linear Guide is a guideway with roller cage, which is a limited stroke linear guide that has precision rollers orthogonalized alternately. The roller cage type R has a unique roller retaining mechanism to achieve a large effective contact length of the rollers and a short roller pitch interval. It is a highly rigid type. Type R Cross roller guideways work effectively to master the medium to high requirements.
Regular Sizes: Vr1, Vr2, Vr3, Vr4, Vr6, Vr9, Vr12, Vr18.

Features:

1, Rolling friction resistance is small, good stability; Low starting friction. Good follow up performance,

2, Large contact area, small elastic deformation, small clearance.

3, Effective movement body, easy to achieve high rigidity, high load movement;

4, Flexible structure design, easy installation and use, long life;

5, Mechanical energy consumption and high precision, fast speed, large bearing capacity.

6, Easy assembly, high frequency, high wear resistance.

7, The best choice of high cost performance, short stroke and high precision.

Application：

Wildly applied to accuracy moving device in heavy duty or light duty,in variety ofmeasuring instrument, printed circuit board drilling machine,or slide table usedin optical measuring instrument, precise gauge in optical experiment,  precision finetuning optical stage, operation mechanism, surveydevice, precise positioning, quantitative  movement, and X-ray Device & Micro-hoe EDM.

Parameter:

Customizable processing cross roller double  linear guide

1. Finite-stroke linear motion: Since the roller moves at 1/2 of the speed of the guide rail relative to the guide rail, if there is no limit, the roller and its cage will be separated from the guide rail after reaching a certain stroke. The movement of the cross-roller guide rail is a finite-stroke linear motion.

2. Can withstand multi-directional loads and torque: Intersected roller, no matter which direction the load comes from, can always have half of the roller can be used to bear, therefore, cross roller guide can withstand multi-directional loads and torque. It can be seen that the bearing capacity of cross roller guide is positively related to the number of rollers.

3. Pre-tightening can be adjusted at any time: the pre-tightening degree of the motion mechanism of the cross-roller guideway can be changed at any time by adjusting the lateral tightening device of the guide strip.
