At Clifton Rubber we have over 40 years experience in covering rollers in both rubber and polyurethane materials supplying a wide range of customers in various industries including food processing, textiles and quarrying.
We can cover new rollers free issued to us, strip and re-cover existing rollers or manufacture complete rubber covered rollers including the fabricated steel or aluminum drum and shaft. Our engineering unit has a highly skilled workforce and advanced CNC milling and turning equipment offering the capability to manufacture high quality steel rollers, roller components and roller assemblies.
We have an extensive range of roller covering equipment including one of the largest diameter autoclaves in the UK. This capacity means we can cover items from small precision rollers for the print industry up to large 3m diameter conveyor rollers used in the mining and quarrying industry. We offer short lead times as standard and can cater for break down situations where rollers need to be turned around quickly.
Our expert team have accumulated many years experience in covering rollers and can help and advise on any issues or queries including material specifications, roller design or end use applications.

Clifton Rubber has been covering rollers for over 40 years and in that time has built an industry leading technical knowledge on the process required to achieve a quality product.
The first key stage of the process involves prepping the roller drum. If we are refurbishing an existing roller then this stage will start by stripping off the existing rubber covering. The face of the drum is then shot blasted in our blast cabinet to provide a strong key between rubber and steel. The face of the drum is then coated with a chemical bonding agent to adhere the compound to the roller.
Once prepped the roller is covered with the specified compound by one of two main methods. The first method uses a mill to masticate the uncured rubber slab compound which is then hand wrapped around the face of the roller, this method tends to be used for larger more complicated items. The second method is to wrap uncured rubber sheet compound around the roller.
Once the roller is wrapped it is necessary to vulcanise the uncured compound to create the solid rubber lining suitable for the end application. This is achieved using an industrial autoclave which applies the heat and pressure required to vulcanise the raw rubber material. At Clifton Rubber we have several industrial steam autoclaves ranging from 0.5m in diameter up to 3m in diameter and up to 8m in length. This capacity flexibility makes us an industry leader in the coating of rollers of all shapes and sizes.
The final stage of the process involves finishing the roller to suit the specified application. Our precision grinding equipment can grind rollers to the most demanding tolerances and our advanced profiling techniques enable us to cut a wide range of patterns to suit specific roller requirements typical finishes include:
As an alternative option and depending on the requirements we can manufacture moulded rollers and currently manufacture a wide range of standard moulded rollers for various industries, see Dahlman Rollers.
For our customer’s benefit we can offer rubber rollers manufactured from the common commercially available rubber and in a wide spectrum of colours and hardness. We stock materials formulated for high and low temperature, food quality (FDA approved), anti-static and flame retardant applications. Our stock materials include:
