Track Range

MHD (Max Heavy Duty) track range supports high load and high-duty applications, such as robot transfer systems for welding and assembly operations in the automotive and heavy mechanical handling industries.

It comes as a kit containing bearing blocks and tracks. The system includes a left and right block assembly. The set of four bearing blocks, each with three large integral crowned rollers, are sealed for the life of the product. The top bearing, which sustains the heaviest load, is a tapered roller bearing. Side and lower rollers are eccentric, eliminating play. The doublerow tapered roller bearings, which are caged and lubricated for life, reduce friction and need no maintenance. And the bearings are aligned in the direction of motion to let the system resist end loading and premature failure caused by axial loading. The bearing blocks run on a pair of 100 × 40-mm flat tracks. The tracks are hardened and fully ground on all surfaces, and come in single lengths of 1.4 m. These highprecision tracks can be butted together for variable length. Applications include aerospace, automotive, robotics, transfer systems, welding systems, and material handling.
