Are you looking for a quiet linear motion system? Then look no further. Our new Vulkollan coated bearings are designed to run in our steel C channels to make a sliding system that is both smooth and quiet.
Choose from V.053P (52.5mm ø) or V.054P (62.5mm ø).
V.054P is also available in stainless steel.
The Oilamid rubbing block can be adjusted – by simply turning a screw – to provide axial guidance and support which helps the system to run true.

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.
Here are some of the possible arrangements:
 |  |  |
| Simple Horizontal System | Combined Horizontal / Vertical | Horizontal Cantilever |
 |  |  |
| 2 Stage Telescopic System | 3 Stage Telescopic System | I Beam Cantilevered System |

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.

There is a vast range of linear motion products on the market and it can be difficult to know which product to select. This article discusses the various types of products available according to their rolling element and explores their advantages, disadvantages and limitations. Finally a selection chart clearly lists each product’s characteristics to help with specifying the best linear motion product.
Some of our linear motion products are shown in the table below:
The primary purpose of linear motion products is to move something from one place to another in one direction along a straight line. Usually this is achieved using a bearing with a rolling element. Traditionally this rolling element would be a ball or roller, but these days some linear motion bearings do not incorporate a rolling element and consequently are known as ‘plain’ bearings. These plain bearings are simply plastic or ceramic bushes and are sometimes lined with PTFE or oil impregnated plastic to help reduce the sliding friction. Continue reading
EURO-VEE BEARINGS
Our Euro-Vee Bearings are available in 4 sizes which can take radial loads from 100kg up to 800kg. A cost effective linear sliding system can be built using our corresponding T Rail and Euro-Vee Bushings for applications requiring either vertical or horizontal movement.
The bearings are sealed and lubricated for life and so will tolerate being used in dirty environments. The Vee Bushings are used to mount these bearings. We have both concentric and eccentric bushings on stock, in both imperial and metric sizes.
A typical system would use a pair of rails with a minimum of four bearings acting as wheels for a carriage. Half the number of bearings would be mounted on the concentric bushings and the other half mounted on the eccentric type. All the bearings are held in position on their bushings by a bolt fixed through the centre of the bushing. By rotating the eccentric bushings it is possible to tighten the bearings onto (or off) the track. The eccentric bushings have a hex head so that they can be rotated with a spanner before their fixing bolts are tightened back up. The system should be designed so that the main loads are taken by the bearings on the concentric bushings.
The T Rail can either be drilled and bolted down (to a square edge) or it can be welded into position. The body of the rail is soft so it can be easily drilled. The top edge of the rail (where the bearing runs) is induction hardened and polished.
It is also worthing knowing that our Euro-Vee Bearings can be run on round (hardened and ground) linear shaft.
Example applications include:
Our Euro-Vee Bearings are also available in stainless steel.
