Our bulldozer track rollers are the “invisible pillars” of the track system, which are suitable for the main models of 20+ brands such as Caterpillar, Komatsu, John Deere, etc., covering from light municipal engineering to heavy mining operations.
The core wheel body is made of QT700 ductile cast iron, hardened by medium frequency quenching treatment, with hardness of HB240-280, and the single wheel can carry up to 12-18 tons, which is not easy to be deformed in the face of high-frequency impacts of mining gravel. For the Caterpillar D7 mining pallet, the wheel surface is specially surfaced with 3mm tungsten carbide wear-resistant layer, and after 10 months of using the D7 in an iron ore mine, the wear of the wheel surface is only 0.8mm, which extends the service life of the wheel by 60% compared with that of an ordinary pallet.
Wetland operation choose “seal strengthening model”, suitable for Komatsu D65 pallet is equipped with three-layer Viton oil seals, waterproof grade IP68, in 1.2 meters deep muddy water environment, the bearings will not enter water for 6 months; cold area special model (suitable for John Deere 650K) filled with -40 ℃ low-temperature lubricating grease, even in the northeast of the -30 ℃ of the cold, still rotate flexibly after starting, no jamming, no jamming. Even in the cold of -30℃ in Northeast China, it still rotates flexibly after starting, and there is no stagnation phenomenon.
All the wheels are strictly processed according to the original size, the error of mounting holes is less than 0.05mm, and the fit between the wheel rim and the track link reaches 99%, which can be replaced in 15 minutes by an ordinary maintenance team without any additional debugging. Measurement shows that under the average daily operation intensity of 8 hours, it can reduce the wear of track chain by 30% and extend the overall replacement cycle to more than 2,000 hours.

The previous carrier wheel did not last more than 8 months in the quarry and then cracked, after replacing this heavy-duty model, the Carter D7 dislikes hard rock every day, and the wheel body has not cracked in 14 months, and the bearings are still very smooth.
This sealed model pallet installed on the Komatsu D65, disassembled to see the bearings clean, 6 months did not change the grease, cheaper than the original half also durable.
In winter -30 degrees Celsius, the previous pallet always stalled in the morning start. After changing the cold zone models, even if the stop for a whole night, John Deere 650K a fire on the go, bearing grease did not freeze, this half a year without delay.
Before the replacement of the carrier wheel always have to spend more than 1 hour to adjust the wheelbase, this Volvo SD160 special models of the hole position is particularly accurate, the bolt on the tightening, 15 minutes to finish. Started to try, the track does not run off, the vibration is much smaller than before.
