Product Description: Linear bearings are a low-cost linear motion system designed for infinite travel and used in conjunction with cylindrical shafts. Due to the point contact between the bearing balls and the shaft, the load is minimized. Steel balls rotate with minimal friction resistance, enabling high-precision smooth movement. A wide range of bearing models is available, with fast delivery and guaranteed quality.

Harbin Roller Bearings - Linear Bearings

Section 1: Introduction to Linear Bearings

Harbin Bearing - Linear Bearings are components that replace sliding friction with rolling friction, consisting of an outer ring, steel balls, a retainer, and a sealing ring. The inner wall of the outer ring features several (not fewer than three) longitudinal tracks, where the steel balls roll in a circular motion along the grooves of the retainer between the outer shell and the guide shaft.

Section II: Features of Linear Bearings

1. Linear bearings are a low-cost linear motion system designed for infinite travel, used in conjunction with cylindrical shafts.

2. Due to the point contact between the bearing ball and the shaft, the load is minimal. The steel ball rotates with low friction resistance, thereby achieving a smooth movement with high precision.

3. Linear bearings consist of a single sleeve, capable of withstanding only radial loads and performing linear reciprocating motion. The radial clearances are available in adjustable and non-adjustable types.

4. Available in standard grade (P) and precision grade (J) accuracy.

Section 3: Applications of Linear Bearings

Harbin Bearings -- Linear bearings are widely used in precision equipment such as electronic devices, tensile testing machines, and digital 3D coordinate measuring devices. They are also employed in the sliding components of industrial machinery like multi-axis machine tools, press brakes, tool grinders, automatic cutting machines, printers, card sorters, and food packaging machines.

IV. The Impact of Temperature on Linear Bearing Lifespan

When the operating temperature of linear bearings exceeds 120℃, the bearing components will lose their original size stability. Therefore, for bearings operating at temperatures above 120℃, special requirements can be made to HRB Company for the selection of bearings that have undergone special heat treatment.
