The Best Linear Motion System?

horizontal and vertical system

Combined Roller Bearings & Mating Steel Profiles are one of the most versatile linear motion systems. Originally used on forklift trucks, the bearings are designed to carry both the axial and radial loads in one unit. The bearings and rails can be used horizontally and vertically, and can also be arranged telescopically to allow for full extension.

The main advantage of Combined Roller Bearings over other track rolling systems is that the smaller axial rollers contact the web of the profiled rails. This helps to keep the system running parallel and consequently prevents it from jamming.

The bearings can be supplied pre-welded to a mounting plate and then simply bolted onto the carriage or they can be welded directly to the structure for a more compact configuration.

With good resistance to dirt and heat, Combined Roller Bearings can be used in many industrial applications: from packaging machines to furnace loaders, brick makers to offshore pipe and cable laying devices, to name just a few.

Multi Purpose Combined Roller Bearings

Combined Roller Bearings were originally designed to be used in forklift truck masts. However, today they are used in a variety of applications (horizontally and vertically) and in a huge range of industries.

The smallest bearing is just 52.5mm in diameter and when used in conjunction with the corresponding steel profile, each bearing offers a load capacity of approximately 550kg. At the top end of the range the largest bearing is 390mm and has a capacity of over 30 tonnes.

The primary benefit of a Combined Roller Bearing over a standard track roller bearing is the integral side thrust roller bearing. This small roller is able to carry lateral loads and ensures free movement of the system.

To make a complete slide you simply need 2 rails and 4 bearings. The bearings can be welded directly to the structure or can be supplied pre-welded to a mounting plate and simply bolted into place. More complex, telescopic systems can be made by using additional rails and bearingsĀ to create further stages.

The application examples below show how versatile this sliding system is.
