Our unique blackened linear guideway systems feature a black oxide coating for the linear rails and complementary black chrome slides. They are ideal for use in applications requiring a degree of corrosion resistance or an aesthetically pleasing finish.
As experts in linear motion we provide you with more than just quality rail systems but the in depth technical support you need to make sure your applications works as efficiently as intended.

Linear guideways are widely used throughout industry for heavy-duty and precise applications.
The use of steel balls and the design of the carriages and guideways mean that the rails can accept very heavy loads and signifi cant moment loads. Our rails have circular as opposed to friction coefficient, lower driving resistance, lower wear and lower energy consumption.
We can cross reference other manufacturers’ part numbers including THK, INA, Bosch, IKO etc.
Rigid and precise
• High load rating.
• High moment load capacity.
7 rail profiles ready for same day despatch. Lengths up to 4 metres.
• A number of load figures are stated for load capacity:
Dynamic Load – this is the main fi gure considered for linear guideways. It is the moving load that the system can bear. It takes account of the total moving load as well as considerations such as impact, vibration and fatigue.
Static Load – this is a load that is constant for an extended time (i.e. the dead load the system can bear before any movement). It can be in tension or compression.
For these linear guideways the radial and axial load capacities are the same.
Moment loads are twisting loads generated by off set loads in either X, Y or Z planes. Moment loads can be reduced by adding further carriages or rails to reduce any twisting of the carriage due to the load off set.
Our new and improved linear guideway systems include the latest “ball chain” technology with the following benefits:
The rotating balls in conventional profile rail guides have point contact between each other. The rotation speed at the contact point is double the speed of the balls. The contact area (A) is so small that the surface pressure (P) tends towards infinity. This leads to heating and wear of the balls and the linear guide system.
The chain system in our new linear guides have a relatively large contact area (A), this significantly reduces the surface area pressure (P). The rotation speeds at the contact surfaces of ball and chain are the same. The ball chain is used to transport the lubricant and to create a lubrication film on the balls. The design of the carriage allows effective supply of lubricant from the lubricant connection to the circulation areas of the ball chains.
This design of the of the ball chain ends in connection with the spacer ball closes the circulation and makes the movement of the carriage smooth and quiet.
It is not possible to keep the distance of the balls (C1, C2) constant in conventional linear guides. These irregular distances between the balls lead to uneven running behaviour.
The new ball chain system also allows the balls to be continuously supplied with lubricant, which reduces wear of the metal. This significantly extends the service life of the system and reduces lubricant and the maintenance intervals.
We can coat our rail with a type of corrosion protective finish:
- Raydent coating; this is an electro-chemical process that applies a black oxide-ceramic layer (approx. 1 micron thick) that penetrates into the metal. As coating takes place at OC the parts are not deformed. Good resistance against acids, bases and solvents.
Where there may be a high level of dust, dirt, weld splatters etc. we can provide bellows covers to protect the rails.
We are entering the next phase of our relocation to a larger factory in Chichester, West Sussex. The next few weeks will see products start to be moved from our current site in Cranleigh, Surrey to the new warehouse.
There are thousands of parts to be relocated and whilst we are doing our best to ensure a smooth transition, this may cause slight delays to some shipments.
We expect to be have all parts relocated and full production capability for our new 35,000ft² facility running by mid-March. Thank you for your understanding.Continue to Website
