PRGH30CA/PRGW30CA roller bearing sliding rail guides linear motion guideway

Short Description:

Linear guide is consisted of rail, block, rolling elements, retainer, reverser, end seal etc. By using the rolling elements, such as rollers between the rail and block, the linear guide can achieve high precision linear motion. Linear guide block is divided into flange type and square type , Standard type block, Double bearing type block, Short type block. Also, linear block is divided to high load capacity with standard block length and ultra high load capacity with longer block length.

    product description

    linear motion guide way

    Linear guides, also known as linear guideway, sliding guides and linear slides, including guide rail and sliding block, it is used to support and guide the moving parts to make reciprocating linear motion in a given direction. Mainly used in high-precision or high-speed linear reciprocating motion applications, can bear a certain torque, and can achieve high-precision linear motion under high load.
