GRV02 GRV02-S Roller Type Stainless steel rail, stainless steel ball retainer, 2.0mm diameter span hole
[GRV02 GRV02-S]


Stainless steel rail, stainless steel ball retainer, 2.0mm diameter span holes

GMT linear motion slide way

Composed of two pieces of stainless steel rails with V-shaped grooves, been hardened and ground forming precisely, and rolling elements.Roller type moves in connective 90 degrees alternately to meet requirement of high parallelism and high flatness.In construction, rolling elements are transmitted in cross-contact by precise roller and V-shaped grooves in rails, and in non-circulation.Variation caused by friction resistance is little as well,even almost no difference between starting friction resistance and dynamic friction resistance in light duty. High accuracy moving and loading capacity could be performed. ◎Comparison of roller and ball character ( refer to P78)

Wildly applied to accuracy moving device in heavy duty or light duty、in variety of measuring instrument、Printed Circuit Board drilling machine…etc, or slide table used in optical measuring instrument、precise gauge in optical experiment、precision fine tuning optical stage、operation mechanism、survey device, precise positioning, quantitative movement、x ray device & micro-hole EDM.

Linear motion needs effective lubrication. Abrasion increase of rolling elements and life decrease would be caused in running without lubrication. Function of lubrication:

1.Reduce friction between running parts greatly, so that it could prevent lock and decrease abrasion.
2.Forming oil film on rolling surface to reduce abrasion of metal medium to extend life of rolling elements.
3.Covering on metal surface to prevent rust.
4. Length is determined by the last number in product name, if you notice a dash followed by an S this will specify the rail is made with stainless steel 440 with the addition of nickel
