The crusher front wall - also called the front frame - is the structural anchor of the jaw crusher frame assembly. It carries the fixed jaw, cheek plate liners, and pitman bearing housings, and absorbs the direct crushing load transferred from the eccentric shaft through the toggle system. A worn or cracked front wall leads to jaw misalignment, liner slippage, and unplanned downtime - which is why mine and quarry operators typically replace it as a heavy-duty structural casting rather than attempt field repair.

Quzhou Horbon Mining Parts manufactures jaw crusher front walls and matching rear end frames as OEM-spec replacements and custom builds, cast and machined to the original dimensional tolerances of PEV130-series and comparable jaw crusher models. Each front wall casting is supplied ready to accept standard cheek plate upper/lower liners, side plate mounting, and toggle seat holder bolt patterns - so it installs as a direct swap without modifying surrounding assemblies.
