square type block 25mm ball bearing precision rail Linear Guides

Short Description:

The linear guide model is composed of 25mm linear rail block and ball bearing linear guide rail. Compared with other traditional linear guides, the linear guide is designed with four rows of single arc groove structure, which can withstand larger loads and therefore run smoothly. Flange or square linear guide has equal load in all directions and self-aligning ability, which can reduce installation error and achieve high precision requirements.
