Wood Hog Parts & Service

Whether you’re replacing your existing machines or any part of it you should contact our service department. We have been engineering and designing equipment and parts since 1976.

Our large inventory includes grate liners bearings, pillow blocks, locking assemblies, tips, hammers and screens for your horizontal, vertical and rear Maintenance wood grinders. We strive to give you the highest quality at a low, low price.

Any part can be custom designed to meet your requirements of increased wear, maximum throughput, and increased density. Our engineering staff utilizes all modern CAD engineering stations with the latest software to design fabrications.

RocWear® also provides spare parts for used wood hogs built more than 30 years ago. In an industry that demands so much from its equipment, it is virtually impossible to find equipment that lasts this long and is supported so well. We understand that when your equipment goes down, it doesn’t just cost you time, it costs you money.

Rawlings RocWear® Inserts are built like our equipment—robust, rugged and reliable — to give you tons more production and less downtime. The design provides the customer with two cutting edges per bit. This means once one side is worn, the bit needs to be simply rotated thus doubling the life of each bit. With less downtime and easier maintenance customers have applauded both the Super Hi-Inertia™ Rotor as well as the RocWear® striker system.
