Linear guide systems are designed to take the lateral and axial loads on themselves while the load on the machine axes is transferred from one point to another.Many linear bearing types have been produced according to the amount of load to be transported or resisted, the angle of the load and environmental conditions.For example, linear guides to be used in a large press feed line, roller guide rails are generally preferred because the load will be too high.While choosing the linear guide, the speed, load, working frequency and environmental factors of the system are taken into consideration.

Also, linear guides have different sizes among themselves according to the conditions of the areas they will be assembled.There are different models such as short wide, short narrow, long wide, long narrow or narrow low.

However, linear motion products are generally classified depending on whether they are roller or ball type.

Below, I list popular roller and ball rail-guide models by brand.I think it will be useful when looking for alternative guide models.
