igus® was founded on October 15, 1964, in a garage in Cologne-Mülheim. Since then, we’ve been creating innovative, lubrication-free plastics that keep the world moving. Our products are used in cars, cranes, furniture, machines, robots, and even bicycles. One example is the igus®, a unique urban bike made from recycled plastic. It showcases many of […]
Our cables are versatile and can be used in many different applications. They work well indoors and outdoors, in hot and cold places, in cleanrooms, and in oily air. But how do these cables perform in the radioactive environments? What is Radiation? Radiation is the movement of particles or waves. They are subdivided into three […]
Anyone who’s worked with metallic insert bearings is likely aware of the frequent — and frankly tedious — relubrication efforts required for such components. Without the proper lubrication, these bearings are almost certain to wear prematurely and fail, leading to costly downtime and lost production. This may seem like an unavoidable reality, however there’s a […]
Several industrial applications require bearings with self-aligning features and this is generally achieved by using spherical bearings. A spherical plain bearing is a bearing that permits angular movement around a central point. igubal is a range of polymer spherical bearings from igus GmbH. Like all the other products from igus, igubal bearings offer many advantages over metal spherical bearings. Here are […]
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 […]
