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.Click on an image to visit the relevant webpage.

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.

Combined Roller Bearings

~ kateharden

Our Combined Roller Bearings consist of a radial bearing, an axial (face) bearing and a weldable hub. The main radial bearing can take very high loads and the axial roller takes side loads and prevents the bearing from crabbing in the channel. Used in conjunction with their mating steel channel it is possible to design and build a heavy duty linear sliding system, for either horizontal or vertical motion. More complicated systems can be built using the bearings and channel to create telescopic and cantilevered solutions. We can help you to select the correct size for your application. Our bearings range in size from an outer diameter of 52.5mm all the way up to 390mm (Jumbo CR range).

The hub of the bearing is weldable so that the bearing can either be welded directly to a structure or to a mounting plate. We keep the standard mounting plates on stock and we can supply the bearing welded to its plate. The standard mounting plates have both threaded holes and thru holes so that the plate can be fixed from the front or the back. We can fabricate bespoke mounting plates to your design.

We also offer a range of combined roller bearings that a have an eccentric adjustable face roller. The height of the face roller can be varied by removing the front face plate and rotating the shaft of the axial bearing, the ends of which are splined.

If your application does not require the axial (face) roller then you could use our Radial Bearings which offer all the advantages of our Combined Roller Bearings and are designed to run in the same steel channels.
