I. Product Overview

Linear bearings are precision components for linear motion, consisting of an outer cylinder, retainer, steel balls, and sealing rings. They offer low-friction, high-accuracy motion at a cost-effective price. Our product series includes cylindrical, flanged, and box-type bearings, with miniature ball bushings providing compact, combined linear and rotational motion. Standard and corrosion-resistant options ensure stable performance in various environments.

II. Working Principles and Usage

Linear bearings operate via steel balls rolling between the outer cylinder and guide shaft, enabling nearly frictionless motion. They are suitable for pure linear movement only; rotational loads may cause damage. For optimal performance, use g6 tolerance shafts and h7 tolerance housings, and consider supplemental lubrication in high-speed or heavy-load applications.

III. Product Series and Features

Standard Linear Bearings – Fully enclosed, dustproof and waterproof, symmetrical for flexible installation.

Open-Type Linear Bearings – Adjustable side slots allow fine-tuning of radial clearance for high-accuracy applications.

Clearance-Adjustable Bearings – Preload mechanism reduces vibrations, ideal for precision instruments and testing equipment.

Flanged Linear Bearings – Integrated mounting flange saves space, enhances rigidity, and offers flexible multi-hole installation.

IV. Materials and Adaptation

Standard Products – High-quality carbon steel with heat treatment and chrome plating, suitable for general industrial use.

Corrosion-Resistant Products – 304/440 stainless steel, resistant to acid, alkali, and humidity, ideal for food and medical industries.

For retainers, we offer two options: steel retainers provide higher strength and durability, making them suitable for heavy-load or impact-load conditions; resin retainers excel in noise reduction and cost control, making them ideal for light-load, low-noise applications.
