RSD | Introduction

Linear bearings type RSD are compact guides for precise linear motion providing high accuracy and an outstanding reliability. Depending on the load requirements they can be fitted with ball- or roller cages. With many years of experience RSD-bearings are the world-wide standard in high-tech applications requiring first class performances and quality with minimum cost.


RSD Linear Bearings

Structure and Features
Depending on the construction, the linear bearing can be fitted with ball- or roller cages with alternately crossed rollers. The construction consists of two pairs linear bearings; one pair consists of two similar 90° V-groove guideways, through-hardened and precision ground, fitted with a cage in-between. Crossed roller cages are used in high-load and high precision applications (note: good dust protection is in this case required). Cages fitted with balls are used in applications which require less capacity, low friction resistance, or where dust and dirt are likely to penetrate into the guideways (balls are affected less by dust or dirt, due to a self-cleaning effect of the balls).

Set RSD

 

Guideways are equipped with countersunk-bored attachment holes, according to a standard configuration. Threaded holes in ends for fixing endpieces and wipers.

 

For the attachment, special screws type GD can be ordered separately.

 

On request we supply linear bearings with roller size ø 18 and ø 24 mm

 

Notes by ordering
One set linear bearings consists of:
4 pcs. guideways (=2 pairs), 2 pcs. cages and 8 pcs. endscrews.


By ordering please specify the following:
1. Quantity and type of guideways.
2. Quantity, type and length of cages or max.stroke/travel.
3. Direction of movement (eg: horizontal, vertical or inbetween).
4. Quantity and type of endscrews or endpieces with or without wipers. (in case of GC and GC-A, only 4 pcs are needed)
