Igus Iglidur PEP Plain Shaft Bearing(Nov 16,2011)
-Standard range from stock;
-Can be used with any shaft material;
-Very cost-effective;
-Easy to it;
-Low coeficient of friction
In standard plain bearing solutions, the shaft has a critical part to play, as important as the bearing itself. With the iglidur PEP bearings, igus takes a forging new trail highlighted by this enclosed and maintenance-free plain bearing design.
When to use it:
Cost-effective polymer bearing system;
Independent of the shaft material and of the shaft surface;
Protection of expensive and sensitive shafts
When not to use it:
For high surface speeds;
At high loads;
For high temperatures;
When low clearance bearings are required
General Properties:
Maintenance-free plain bearings are generally described as being able to slide on the shaft without any additional coating and/or lubrication. It is evident that shaft materials are as important as the bearing itself. igus is forging a new path with a plain bearing that is self-contained and maintenance-free. iglidur PEP is an innovative design for lubricant-free polymer plain bearing systems with an inner and outer ring. The special feature; the sliding surface is the inner ring, and for the first, time shaft materials and shaft surfaces are not a concern. Even threads, rust and scratches do not affect the performance or reliability. With the control over the sliding surface and through considerable testing, the long term behaviour of the bearing system can be predicted precisely. Similar to ball bearings, the inner ring turns with the shaft in the polymer PEP plain bearing. Relative movements of the shaft with respect to the bearing are eliminated. This protects the shaft surface from wear and saves costs. An additional beneit; even the most sensitive or unusual materials can be used as the rotating shaft with this new polymer plain bearing. Due to the bearing materials used, the PEP polymer bearing is totally corrosion-free.
Wear Resistance:
The wear resistance of PEP is of signiicant interest. For loads up to 1 N/mm the test results are compelling. Here iglidur J iglidur PEP polymer bearings obtain values that are comparable to most wear resistant metal-backed bearing systems. This is a very positive result, when you consider the reduced costs compared with the required shaft surface inish which is demanded by traditional bearings.The consistently low coeficient of friction is also an advantage to the user. Since the running surfaces are fixed, the tribological data can be calculated. The coefficients of friction of the PEP bearings are no longer based on shaft materials or surface properties. If necessary, the coefficents of friction can be reduced further with a small amount of lubricant.
Fitting:
The installation of the PEP plain bearing could not be easier or faster. The bearings are manufactured to be pressed fitted into a recommended housing bore of H7 tolerance. Then, the shaft is inserted and fits tightly onto the inner ring. The inner bearing is clipped into the outer ring. This design makes it possible to pull the shaft out without removing the inner ring.
