Stern rollers are supplied as single or twin rollers. They are made in a range of sizes up to those intended for AHTS with the highest bollard pulls handling the heaviest deepwater moorings. From the simplest rollers we are using sfearical bearings. Bigger rollers we are offering both single and double ended rollers up to 2×500 ton swl
Composite bearings in combination with a closed loop cooling/lubricating system, utilising biodegradable lubricant, provide low rotational resistance in all operating conditions. Each of the rollers can be equipped with a measuring device, counting rotations, for estimating the length of wire rope or chain moving out or in over the roller.
