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.
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.
A Tolerance Ring is a corrugated metal strip which is used to act between two cylindrical objects to create an interference fit. The corrugations act like springs, fastening the two objects together. They can also be used for torque control and can provide overload protection using torque slip.
They fall into the general category of friction fasteners. They are made from spring steel or stainless steel.
There are two different types of tolerance ring. Our AN type are used to hold an object into a housing. Our BN type is used to hold an object onto a shaft. If for example the object is a bearing then you would use the AN type on the outer diameter and you would use the BN type in the bore.
The use of a tolerance ring can reduce assembly times, permit larger machining tolerances and can compensate for misalignment and thermal expansion between components. A tolerance ring also allows for disassembly.
This blog is being developed to provide you with more information about our product range. Each blog will focus on a product range. The aim is to highlight the advantages it offers and give you an overview of typical applications.
