The range of ITR sprockets includes equipment from JCB® 8008 (operating weight of the machine 0.95 tons) to KOMATSU® PC 1250 (operating weight of the machine 110 tons).

ITR Sprockets - Functionality

Bolted mounting. The method of tightening is specified in the machine's operating manual. It is important to obtain information regarding the installation of the track sprocket bolt and the torque specifications.

Functions: Transmitting drive loads from the main gearbox to the track via the bushings. Durability equal to at least one side of the bushing, crack resistance. Track sprockets are produced to fit precisely to the bushings. Strictly controlled manufacturing processes to ensure proper equipment assembly. Advantages of bolted track sprockets: Limited maintenance and shorter downtimes. No risk of misalignment. Reversible - transferring sprockets to the opposite sides of the machine can increase the lifespan of the track sprocket. The crowns of the sprockets are forged or cast from deep-hardened steel, which provides nearly twice the hardening depth compared to regular steel. Material SCMn3A. Hardening 50 – 55 HRC.

The production of sprockets and segments by ITR for mini excavators is suitable for a wide selection of models of crawler-driven machines.
