Replacement Z51 fibre gear (51 teeth) for the Bizerba model 22 meat grinder. It is the transmission gear made of fibre instead of metal: a classic design choice on professional meat grinders, because fibre makes the meshing quieter and acts as a sacrificial element, failing before the steel gears and the motor if the auger jams (bones, foreign objects, overload).

• Material: fibre
• Teeth: Z51 (51 teeth)
• Compatibility: Bizerba model 22 meat grinder
• Item reference: BIZTRI0006

Typical symptoms calling for replacement: the motor runs but the auger does not turn or "skips" under load, a rasping noise from the gearbox, fibre dust or fragments in the transmission, visibly worn or broken teeth. Replacing a damaged fibre gear promptly prevents vibrations from being passed on to the other transmission components.

When replacing it, clean the gearbox of residues from the old gear and check the condition of the mating gears before reassembly.
