Grate bearing for flake and cross-beam grate: shaft-end fit and dimension check

This bearing serves both flake-type chain grates and cross-beam chain grates. On either type the chain belt is carried by a front and a rear shaft, and the bearing sits at the shaft end. We supply replacement parts in this size.

A part shared by two grate types

The chain grates we supply include the flake type, the cross-beam type and the chain-belt type. The cross-beam grate stands alongside the flake grate, both use the same shaft-end support position, and this bearing is shared by the two. State the grate type when ordering so that the installation dimensions and the material can be checked.

Shaft-end support and the wheel set

Parts that can be matched from the same series include the front bearing, the rear bearing, rollers, chains and the wheels that fit the shaft. Checking the shaft and wheel mating surfaces while the bearing is replaced prevents uneven wear once the new bearing is fitted.

Confirming dimensions

Replacement parts are made to OEM dimensions and tolerances, and mating dimensions follow the original machine drawings. The material is selected to the drawing requirements; the grate spare-parts material system covers grades from HT200 to RTCr2Si4Mo, and the products meet the NB/T 47050-2016 technical standard.

Supply and matching parts

The partner factory handles dispatch, and we can advise on selection and match the parts into a set. Please provide the grate type, the shaft-end drawing or a physical sample, the material requirements and the quantity.
