Cross roller guide Introduction

Crossed Roller Way is a linear motion rolling guide that incorporates a roller cage between two linear ways with V-shaped surfaces that act as track grooves. Because the cylindrical rollers are alternately crossed, this arrangement can handle loads in any direction while providing extremely high-accuracy and smooth linear motion. Models are available in various sizes which can be selected based on the application.

 Advantages:

1. Standard Type and Module Type;

2. Smooth Motion

3. High-Carbon Chromium Bearing Steel and Stainless Steel Types

4. Easy Mounting

5. Interchangeable in mounting dimensions.

6. Smooth and extremely high-precision operation

Precision Rail Cross Ball Rail Micro Module The cross roller guide pair is composed of two guide rails with V-shaped raceways, roller cages, cylindrical rollers, etc. The cylindrical rollers arranged in a cross-aligned manner reciprocate on the precision-ground V-shaped raceway surface , Can bear the load in all directions, realize high-precision, stable linear motion. A set of guide rail pair is composed of 4 guide rails with V-shaped grooves, two cages (including rollers held on them), and anti-dropping pieces installed on the ends of the guide rails to prevent the cage from punching out.

Specifications for crossed roller slides include linear travel, dynamic load-carrying capacity, maximum linear velocity, and physical dimensions.

Linear travel is measured in inches (in), feet (ft), millimeters (mm), or centimeters (cm). 

Dynamic load carrying capacity is measured in ounces (oz), pounds (lbs), grams (g), or milligrams (mg).

Maximum linear velocity is the speed at which the positioning carriage moves. Units of measure include inches per second (in/sec), feed per second (ft/sec), millimeters per second (mm/sec), and centimeters per second (cm/sec).

Physical dimensions for crossed roller slides include base length, base width, top height, carriage length, and carriage width.

Base length is the length of the base measured parallel to the main axis of travel. Base width is the width of the base measured perpendicular to the main axis of travel.

Top height is the height of the unit from the base to the top of the carriage.

Carriage length and carriage width are, respectively, the length and width of the carriage measured parallel to the main axis of movement.

Crossed roller slides differ in terms of applications and features.

The characteristics of cross roller guide

Features:

1. Low rolling friction resistance and good stability.

2. The starting friction is small, the follow-up performance is good, and it is easy to start.

3. Large contact area, small elastic deformation, many effective moving bodies, easy to achieve high rigidity and high load movement.

4. Flexible structure design, easy installation and use, low noise.
