SMG series linear slide rail

1、 Characteristics of SMGN/W series miniature ball linear slide rail

1. Small size, light weight, suitable for small equipment use.

2. Adopting Gothic four point contact design, the product has uniform force distribution, high rigidity, high precision and other characteristics.

3. The slider is equipped with a dust-proof baffle and a steel retainer, and can be freely removed with interchangeability when precision allows.

4. The widened type can enhance the product's load capacity and can be used in a single track.

2、 SMGN/W series basic structure

3、 Scope of application

The SMGN/W series is widely used, including semiconductor manufacturing equipment, medical equipment, precision measuring equipment, automation instrument equipment, precision machine tool equipment, and other small linear sliding devices.

6、 Accuracy level

SMGN/W series slide rails offer three types of precision: ordinary, precision, and precision. Customers can choose the appropriate precision according to their accuracy requirements

Company: mmAccuracy Table of Interchangeable Micro Slide

accuracy class		Ordinary level (C)	（H）	Precision grade (P)
Allowable dimensional error for height H		±0.04	±0.02	±0.01
Allowable dimensional error for width N		±0.04	±0.025	±0.015
Single Pair	Mutual error of height H	0.03	0.015	0.007
Single Pair	Mutual error of width N	0.03	0.02	0.01
The complex number only pairs with the mutual error of height H		0.07	0.04	0.02

7、 Pre pressure

SMGN/W series slide rails offer three types of pressure: normal clearance, no preloading, and light preloading

Pre compression level	mark	preload	Applicable accuracy
Ordinary gap	ZF	Precision gap 4-10 μ m	C
No preloading	Z0	0	C~P
Light preloading	Z1	0.02C	C~P

Note: C in the pre pressure is the dynamic rated load
