LR Guide Bering

The outer circle of the product is machined to a rounded surface of R500 (suffix with U), so that the product is well stressed in the process of use.

The roller adopts the internal structure design of deep groove ball bearing or double row angular contact ball bearing and the thickened outer ring, so that the roller has higher bearing capacity.

The rollers are made of high quality bearing steel, heat treated, precision ground and filled with high quality multi-purpose grease for long life. The rollers are protected from dust by metal dust caps or rubber seals.

Specialized processing equipment and testing equipment ensure the accuracy of the roller shape, mature processing technology and strict quality inspection process make all the roller outer ring radial runout and working surface true roundness good, so that the guideway system in operation with minimal error, smooth operation and extremely low operating noise.

Features:

Low resistance, long life, wide application
With R500 rounded surface support roller in the work, the roller and the guide between the force uniform, avoid stress concentration, friction resistance is small, so that the product’s working life increased a lot. Most of the double-row support rollers can also be repeatedly lubricated through the grease filling holes on the inner ring to adapt to the harsh working environment.
Simple and easy to install
The eccentric shaft and concentric shaft of the roller bearings make the installation very easy, and the eccentric amount of the eccentric roller can be adjusted to get a suitable preload.
Smooth running and small error
LR series support roller in addition to the standard production of rolling bearings, but also adopted a special processing technology, in order to fit the inner ring fixed, the outer ring rotation of the special working mode.

Appliaction:

LR series roller bearings are the most widely used and economical products in linear guide rollers, which can be adapted to cylindrical guide rails, with smooth running, small error, very low running noise and high running speed. Widely used in embroidery machines, linear guides, industrial robots, automation equipment, cutting equipment, mobile guides, production lines, transmission machinery, medical instruments, printing machinery and other CNC equipment.
