Caterpillar D8K bulldozer single(double) track roller
◎ Single and double-edge track roller suits for excavating machine and special machinery ranging 3 to 50 tons.
◎ Double conical sealing and lifelong lubrication designing enable the track roller to have longer service life and perfect performance in any circumstances.
◎ The shell made by hot forging treatment obtains superior structure of internal materials and fiber
◎ Differential quenching or feed-through quenching heat treatment is effective in crack resistance.
