Linear guide is consisted of rail, block, rolling elements, retainer, recirculator, seal etc. By using the rolling elements, such as balls or rollers between the rail and block, the linear guide can achieve high precision linear motion.
Yigong has two kinds of linear guides, ball guide(Model: GGB) and roller guide(Model: GZB), and accuracy with 2, 3, 4, 5 grades. Grade 5 is the normal most simple one.

Roller guide: GZB(heavy load with roller cage)
Size: 35mm, 45mm, 55mm, 65mm, 85mm, 100mm, 125mm
Rail length; Max. 6m/pc
Production according to customer's request, block and rail assembled for the shipping.
Characteristic: Heavy load, low noise, high speed, high accuracy;
Normally used for machining center, grinding machinery, heavy machinery etc.
