Main characteristics


Recirculation system of the ball rolling elements: carriage, profile guideways, direction system and fixing wire.

Lubrication system: grease nipple is available for MGN15, grease gun can be used.

Dust proof: end seal, bottom seal (optional for 12, 15 sizes), cap (12, 15 sizes)

Special properties of MGW series

1. Better perception of the load moments due to the wider shape.
2. Gothic profile of the rolling surface is extra rigid in all directions.
3. Steel balls are moved in small separator of the bearing, and do not fall out when a carriage is removed from the rail.
4. All metal details are made of corrosion-resistant stainless steel.

Application

MGN/MGW series can be used in many directions, such as semiconductor equipment, printed circuit board assembly, medical equipment, robotics, measuring instruments, office automation and other directions requiring the miniature guideways.

Item numbers of MGN/MGW series


The profile rail guideways are divided into interchangeable and non-interchangeable models. The dimensions of both models are identical. Interchangeable model is more convenient because you can replace the carriage and rails without any problems. Their accuracy is nevertheless lower than that of non-interchangeable models.

Due to the strict control of the compliance with specified sizes, interchangeable models are an excellent choice for consumers having profile rail guideways mounted on the same axle not in pairs. The item serial number indicates the size, model, accuracy class, preload, etc.

Accuracy of the interchangeable systems

Accuracy classes of MG series are divided into three classes depending on the accuracy: normal (C), high (H) and precision (P). A suitable model can be selected in accordance with the requirements of the machine in which profile guideway will be installed

Preload

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

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

Class
Code Preload Accuracy
Light Clearance ZF Clearance 4~10μm  C
Very Light Preload Z0 0 C-P
Light Preload Z1 0.02C C-P
