Good Quality Undercarriage Parts Excavator Carrier Roller Support Roller Wholesale
The support roller (carrier roller) is mounted above the track and fitted in the middle of the track frame, serving multiple critical functional roles for crawler excavator undercarriage systems.
1 It effectively supports the upper track chain and prevents excessive sagging and violent shaking during operation. It also avoids direct collision and friction between the track and the main frame structure.
2 It greatly lowers the traveling resistance of the excavator during moving and working processes. The upper track can roll flexibly and smoothly without abrasion against the frame.
3 It provides auxiliary track guiding function together with guide wheels and drive sprockets. This coordinated structure ensures stable track operation and effectively reduces track deviation and derailment.
4 It undertakes moderate load-bearing and shares part of the track overall weight. It offers stable stress support when the excavator travels uphill or on rough bumpy terrain.
How to select a carrier roller for your excavator/bulldozer/loader ?
When you select a carrier, it is important to select according to your excavator's brand and model.
6 tons, 13 tons, 20 tons, and 30 tons cannot be mixed, as the size, shaft diameters, and installation distances of these carrier rollers are different. The groove spacing of the carrier roller must be consistent with the track pitch, otherwise it is very easy for the chain to get stuck, wear out quickly, and fall off easily.
