• Durability

The rail is made of precision-ground steel with a hardened surface for durability and wear resistance.

• Flexible Installation

The cylindrical shape allows for and requires less stringent mounting surface conditions, making installation easier than with square rails.

• Radial Load Support

Primarily designed to support radial loads, with limited ability to handle side loads and torque.

• Low Friction 

Rolling contact reduces friction, ensuring stable and quiet operation.

• Multiple Diameters

Available in various standard diameters to suit different load and space requirements.

• Custom Lengths

Rails can be supplied in custom lengths to fit specific application dimensions.

• Surface Treatment 

Options include hard chrome plating or other coatings to improve surface durability.

FAQ

Q: What is a Round Linear Guide Rail?

A: A Round Linear Guide Rail is a cylindrical linear motion system consisting of a hardened steel shaft and a matching linear bearing block that moves along the shaft with rolling elements to provide smooth and precise linear movement.

Q: How does a Round Linear Guide Rail work?

A: The linear bearing block contains rolling elements (balls or needles) that reduce friction between the block and the shaft, allowing smooth linear motion with minimal resistance.

Q: What are the main components of a Round Linear Guide Rail?

The system consists of two main components: the cylindrical steel shaft (rail) and the linear bearing block with integrated rolling elements.
