Standard Steel Rollers

Mild steel rollers are by far and away the most popular roller type. They are economical, flexible, and very sturdy.

CCBA can provide a wide range of sizes, finishes and shaft types

Standard rollers

This is a bit of a misnomer, as there is no such thing as a truly "standard" roller; every customer has their own specific needs. We can manufacture rollers in a range of different diameters and lengths; below is a summary of our most popular roller types (though we can manufacture many more sizes than this).

Roller Diameter Wall thickness Load (max) Max length

The narrow the roller, the lower its maximum recommended length. As an example, a 25mm diameter roller (our smallest) might start to 'sag' in the middle if it is longer than about 750mm, depending on the load it is put under. The larger 76mm rollers can be made much longer... up to 1800mm... and we CAN make them even longer than that.

Carrying capacity varies between 20Kg up to 600Kg, though we can make heavier duty rollers if required. (see also Conveyor Drums for the really heavy-duty stuff).


A standard roller features internal bearings, allowing the roller to rotate around its shaft. The shaft can be fixed directly onto the frame of the conveyor as a result, without the need for bulky external bearing blocks.

To assist with this, we can provide rollers with a variety of different shaft endings. For lightweight applications, and gravity-roller conveyors, a very popular option is a plain round shaft that is sprung-loaded. This allows the roller to "snap" into holes drilled along the conveyor frame.

Other common configurations are to have a non-sprung-loaded shaft with holes drilled through the ends of the shaft, allowing the shafts to be wired together on the outside of the frame, preventing them from falling out

At the heavier-duty end of the spectrum, the shafts can be threaded (either externally or internally) to allow nuts or bolts to firmly hold the roller in place.

Another option is to 'flatten' the ends of the shaft, allowing them to be captivated in slots in the conveyor frame.

(you can click the above pictures to see a larger view, which opens in a new window).

This last option is also used in "drive rollers". These are distinct from gravity rollers in that they are powered by an external motor, with the flattened shaft allowing the roller to "engage" with the motor. Such rollers require external bearings. This technique is normally restricted to the heavier-duty cousin of the roller: the Drive Drum. . However, for very light-duty applications, a roller CAN suffice in this role.

Lagged Rollers

CCBA can provide rollers with a material coating, reffered to as "lagging". This is frequently used to improve the grip of drive rollers, or to prevent gravity rollers from scratching or damaging the carried product. We can provide lagging in PVC, food-grade PU, standard rubber, and Nitryle non-marking rubber, among many other materials.

Zink Plating

If you want your rollers to really "shine", then we can produce zink-plated rollers that give a "chrome" look. This does not change the characteristics of the roller, other than to provide a small degree of water-resistance, and is primarily cosmetic.
