igus, develops maintenance-free and above all lubrication-free solution for transport and guide rollers, which are made of blue light weight PVC tube and FDA-compliant two fixed flange ball bearings made up of in-house material xirodur B180 and stainless steel balls under the brand name xiros. These xiros guide rollers are particularly important for labelling, packaging and food applications due […]
Our health is our most important possession and no components of the bearings or linear guide should ever harm it in anyway. Where there is possible contact with food, the requirements placed on each component are different from those in other cases. The linear guide system, i.e. guide rails, shafts, linear bearing housings, screws and […]
If you go into the problem of threads, you often encounter the word “self-locking”. But what does “self-locking” mean exactly in conjunction with lead screw technology? And what are the differences between high helix threads and trapezoidal threads? We have explained it briefly and simply. Self-locking means that lead screw nuts and lead screws cannot […]
The question of clearance is often asked in the case of lead screw nuts made of polymer. This describes the lost motion, i.e. the “dead travel” on the lead screw, or in other words the gap between the thread flanks of the lead screw and the lead screw nut. The term clearance is often used […]
At first glance, many advantages of plain bearings sound attractive for use as roller. They use less space than roller bearings, require no additional lubrication (depending on their type) and do not suffer as much from dirt and cleaning agents. On top of that they weigh less and are cheaper. But as usual, devil is […]
