About Us

Our 400-72.5KW conventional rubber tracks are for use with undercarriages of machinery specifically designed to operate on rubber tracks. Conventional rubber tracks do not make contact with the metal of the equipment’s rollers while in operation. No contact equals increased operator comfort. Another advantage of conventional rubber tracks is the heavy equipment roller contact will ONLY occur when aligning the conventional rubber tracks to prevent roller derailment.

Our rubber tracks are made from specially formulated rubber compounds that resist cutting and tearing. Our tracks have all-steel links that are designed with exact guide specifications to fit your machine and ensure smooth equipment operation. The steel inserts are drop-forged and are dipped in a special bonding adhesive. By dipping the steel inserts rather than brushing them with adhesive there is a much stronger and more consistent bond within; This ensures a more durable track.

Purchasing rubber tracks for your equipment from us can increase the versatility of the functions that your machine can perform. In addition, replacing your old rubber tracks with new ones from  ensures peace of mind that you won’t have machine downtime – saving you money and getting your job done on time.ronger and more consistent bond within; This ensures a more durable track.
