X-Tek Innovations in Oldham has implemented igus bearings on an innovative cable reel for cameras used in underground pipes. The injection moulded, polymer bushes were selected for their minimal wear, long life, low cost and ability to handle arduous conditions.
The XT1750 & XT2500 Cable Reels from X-Tek Innovations are heavy duty, but designed for maximum ease of use. The reel is highly manoeuvrable, even over rough terrain, and is designed to maintain a low centre of gravity. Large wheels and pneumatic tyres are used for maximum stability.
X-Tek required the reel's bearings to resist harsh, wet conditions, and to be self-aligning. The company also needed to reduce the total cost of fabrication. The company discovered igus polymer bearings would be ideal, predominantly because they offer low cost, long life and can be used in dirty environments. T
he reel uses two iglidur(r) M250 thrust washers, which are low weight, maintenance free and non-corrosive. Two igubal(r) EFSM spherical flange bearings were also specified for the same reasons and because they are self-aligning.
The cable reel must withstand mud, sand and sewage in the environment it operates. Both types of bearing work well despite this dirty environment. The bearings are also resistant to damage and can cope with the shock and impact the reel undergoes while being transported.
The low cost, quick delivery times and high level of technical support were additional reasons for choosing igus.Dave Parnaby, Managing Director at X-Tek, says he is over the moon with the bearings' performance to date.
The unique application was shortlisted for the manus plastic plain bearing design awards at the end of 2004. The contest is set to run again in 2006.
