Guideways RG

The rolling ball elements are replaced by rollers in the new profile rail guideways of RG series by HIWIN brand. The models of RG series have a ultra-high rigidity and load capacity. The contact angle is 45 degrees. Due to the linear working contact surface deformation is minimized because of the perceived loads and very high rigidity and load capacity are achieved in all four directions of the load action. The linear guideways of RG series provide a high productivity in a very precise manufacturing and have a great resource


HIWIN's linear guideways of RG series


 

Rotation system of the rollers: carriage, rail, end seal, circulation paths, rollers.

Lubrication system: grease nipple and oil adapter.

Dust proof: end seal, bottom and double seal, cap, scraper.

Optimum design

To ensure the optimal structure of the carriage and rail, FEM analysis was performed. The unique design of the circulation path of RG series provides the superior linear displacement.

High rigidity of the system

The rollers are used as the rolling elements in RG series. The rollers have a larger contact area than the balls and have a greater load capacity and rigidity.

High load capacity

Due to the four row design RG series have a uniform loadability in all directions. Rail guideways of RG series have a higher load capacity at a smaller size than the conventional rail guideways with the balls.

Extended service life

A basic dynamic load capacity matches the ISO standards (ISO14728-1). Compared with conventional ball guideways, RG series have a higher load capacity, which leads to an extended service life.

Accuracy classes

Accuracy classes of RG series are classified into:

  • high (H),
  • precision (P),
  • super precision (SP),
  • ultra precision (UP).
The choice depends on the equipment requirements.

Preload

Definition

The preload can be set for each profile rail guideway. For this purpose oversized balls are used. Usually a negative clearance between the rolling surface and balls is used in the profile rail guideways for increase of the rigidity and accuracy.

Preload classes

There are three types of standard preload for different application conditions.

"C" means the dynamic load capacity in the column "Preload".

Class Code Preload Condition
Light Preload Z0 0.02-0.04C Certain load direction,low impact, low precision required
Medium Preload ZA 0.07C-0.09C High precision required
Heavy Preload ZB 0.12C-0.14C High rigidity required, with vibration and impact

Standard and maximum rail length

Standard and maximum rail length
Hiwin offers a standard rail length to the needs of the client. For non-standard length E recommended size should not exceed 1/2 of the pitch (P). It prevents the instability of the rail end.
L=(n-1)*P+2*E

 

L-total length of guideway (mm)
n-number of mounting holes
P-distance between the two holes (mm)
E-distance from the center of the last hole to edge (mm)
