According to common experience, 50% or more of the maintenance costs during the life of a crawler dozer or loader belongs to undercarriage maintenance and repairs. In a machine fitted out with traditional undercarriage the sprocket slides on the external surface of the bushing during normal operation, causing bushing and sprocket wear.

Increasing the life of undercarriage components is the winning strategy to reduce ownership and operating costs.
In the new system ROBUSTUS TM the bushing rotates when in contact with the sprocket, reducing the bushing and sprocket friction and wear and thus enabling longer life. As a consequence, it is not necessary to turn bushings and pins and replace sprocket segments during the whole life of the undercarriage.A wider track link rail (“big footprint” track link) provides an extended running surface area, balancing the wear of all components and eliminating scalloping wear in the contact between chain and roller and between chain and idler. The reinforced hardware improves joint stability. The resulting dampening of vibrations and noise assures more comfortable ride and maximum control of the machine during the operations. Berco Positive Pin Retention and an improved seal design produce a lasting seal capacity and assure long life to the complete system. The new system is fully compatible with existing frames and standard components: (D6H and D5H machines), older machines can be easily upgraded to increase their productivity and the life of the undercarriage. In the same way ROBUSTUS TM is forward-compatible with the new generation undercarriages equipped with parallel or twin links.
The innovative rotating bushing tracks system can be easily installed on any machine at any time. With a simple operation and no extra work you can extend the life of your undercarriage, improving reliability and reducing costs. Berco field tests proved that the new system increases the track life of 35 percent, with a maximum of 6,000 hours of operation without maintenance; and this means cutting operating costs up to 30 percent.
