The flake / big chain belt front bearing is mounted on the front shaft of flake grates and big chain belt grates and supports the front end of the chain belt. We supply replacement bearings to the original drawings.
Support position on the front shaft
The chain belt of a chain grate runs around the wheel sets at the front and rear ends, and the front bearing sits on both sides of the front shaft, carrying the load of the chain belt at the front. The chain belt of the big flake series is wider, so the matching front wheel, rear wheel and rollers are also larger, and the front bearing belongs to the same wheel set as these parts.
Matching with front and rear wheels and the chain
Parts that can be supplied as a set in the same series include the big flake front wheel, big flake rear wheel, big flake roller, big flake chain, big flake splint pin shaft and big flake side liner. When replacing the front bearing, the wear on the front wheel and chain is normally checked at the same time, to avoid a mismatch between new and old parts. Bearing fitting dimensions are confirmed against the original drawings, and replacements are made to OEM dimensions and tolerances.
