HIWIN HGL20HA-ZAC Linear Guideway Block

Some of the main features are listed below.

(1) High positional accuracy
When a load is driven by a linear motion guideway, the frictional contact between the load and the bed desk is rolling
contact. The coefficient of friction is only 1/50 of traditional contact, and the difference between the dynamic and the
static coefficient of friction is small. Therefore, there would be no slippage while the load is moving.
(2) Long life with high motion accuracy
With a traditional slide, errors in accuracy are caused by the counter flow of the oil film. Insufficient lubrication causes
wear between the contact surfaces, which become increasingly inaccurate. In contrast, rolling contact has little wear;
therefore, machines can achieve a long life with highly accurate motion.
(3) High speed motion is possible with a low driving force
Because linear guideways have little friction resistance, only a small driving force is needed to move a load.This
results in greater power savings, especially in the moving parts of a system. This is especially true for the reciprocating
parts.
(4) Equal loading capacity in all directions
With this special design, these linear guideways can take loads in either the vertical or horizontal directions.
Conventional linear slides can only take small loads in the direction parallel to the contact surface. They are also more
likely to become inaccurate when they are subjected to these loads
