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 bearings to create further stages.

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

Being so versatile, combined roller bearings can be used in many applications including:

  • Lifting & Handling Equipment
  • Offshore Cable & Pipe Laying
  • Specialised Vehicles
  • Packing Machines
  • Furnace Loaders
  • Agricultural Equipment

Sliding Gardens

When the Landscape Director from N T Killingley contacted us about sliding a planter in and out of a glasshouse at RHS Chatsworth, our Technical Sales team listened to his specification and suggested various options. Their requirement was a system that was simple to install and robust enough to carry the weight of a laden planter, but most importantly would not cost a fortune as the display was temporary.

The combined roller bearing system met this criteria. By using the rails upturned, there was very little set up involved and the bearings and mounting plates were simply bolted to the underside of the planter.

The end result was a system that was discreet and could be operated with very little effort. The display formed part of the “Garden for a Changing Climate” at RHS Chatsworth in June 2017 and featured on BBC’s Gardeners World.

The RHS video of the garden can be viewed here. And the BBC Gardeners World episode can be viewed here (approximately 41 minutes in).

If you need help to specify a linear sliding system, please contact us. We have a team of Engineers & Designers who can guide you through both selecting the most suitable product and specifying the correct size.

Did you know…?

Combined roller bearings can be used in a huge variety of applications. In the simplest arrangement (4 bearings & 2 rails) they can be used to make a forklift mast (vertically), a telescopic slide (horizontally) or just to slide something from A to B.

Combined Roller Bearings and Mating Steel Profiles (Rails)

The main advantage of a combined roller bearing is the small axial roller that helps to keep the system running parallel and prevent it from jamming or crabbing. The combi bearings come complete with a weldable hub so they can be welded directly to your structure or, for ease of maintenance, they can be purchased pre-welded to a mounting plate. This mounting plate is simply bolted on with 4 bolts.

Used together with the mating steel channels (rails), the combined roller bearings offer a simple and cost effective way to make a heavy duty linear slide system. The smallest bearing diameter is 52mm, and the largest Jumbo bearing is 390mm. The rails are available in both C and H (or I) sections.

Precision Range: For heavy duty applications requiring high precision, the Precision Combined Roller Bearings offer a reduced clearance between the bearing & the rail and consequently minimise the play in the system. The rail is machined in the web and the bearing diameter is increased to match this, with a tolerance of 0.2mm – 0.4mm.

Jumbo Range: For ultra heavy duty applications, the Jumbo bearings can offer an affordable solution.

Corrosion Resistance: In some environments (e.g. Offshore) it can be beneficial to use a corrosion resistant system. The Thin Dense Chromium coating withstands salt spray and can considerably improve the operating life. We can offer all of the ranges with coating.
