Track Roller Bearing with Double Row LR

Track Roller Bearing with Double Row LR
ISUTAMI LR track roller bearing with double rows, also known as double rows cam roller bearing or double rows cam guide wheel bearing. This series can be used in the heavy loads track or used as an idler wheel. It is widely applied in the occasion of reducing friction. The outer circumference of the product is processed into a circular surface of R500 (suffix with U), so it makes the stresses well when rollers working. The roller adopts the internal structure design of the double row angular contact ball bearing and the thick outer ring, so that the roller has a higher bearing capacity. The roller is made of high quality bearing steel, processed by heat treatment and precision grinding. And it is internally filled with high-quality multi-purpose grease. The roller is dust-proof with a metal dust cap or rubber seal.

Track Roller Bearing with Double Row LR Features

Systems using the LR series of support rollers have the following features:

1.Low resistance, long service life, widely-use
Track roller bearings with crowned runner surface R500, make its stresses in well-distributed between rollers and track when working, thus the stresses centralization are avoided, the friction resistance are reduced and the service life of rollers have been improved a lot. Most of the double row cam rollers can be relubricated through the filling hole on the inner ring to accommodate harsh working conditions.
2.Easy installation
After rollers assembled the concentric or eccentric pivot, installation can be made convenient. To adjust the eccentric one's eccentricity, the rollers can get the fitting preload.
3.Smooth running, minimum error
Besides we produce the series LR cam roller bearing according to the standard of rolling bearings, we also make the strict control on the rotary accuracy of outer ring in order to meet special working mode that inner ring is fixed while outer ring running.
