Unfortunately no – the colour is usually due to the composition of the respective material and there are often only a few individual dyes that are simultaneously suitable for a material and do not have an adverse effect on its tribological properties. The wear behaviour depends on the composition of the material (the dye being […]
1.1 igus carries out a pin-gauge test, also called a “go/no-go test”, in order to ensure that our bearings meet the specifications and function properly once installed. First of all, the bearings are press-fitted in a test housing. It must be ensured that the bearings are undamaged when they are fitted. A housing chamfer is […]
Some engineers are reluctant to consider plastic bearings in their designs. Perhaps they have become accustomed to metal or bronze bearings for years, or they simply doubt the suitability of plastic for difficult applications or environments. However, plastic bearings can withstand extreme temperatures, enormous loads and high speeds. One has to know the pros and […]
The key word “RoHS” is based on EU directive 2002/95/EU (“RoHS 1”) which was replaced on 3 January 2013 by EU Directive 2011/65/EU (“RoHS 2”).The Directive regulates the restriction of undesirable ingredients in electrical and electronic equipment placed on the EU market. The abbreviation RoHS stands for “Restriction of (the use of certain) Hazardous Substances”.Since […]
Bearing wear means material erosion on the sliding surface, i.e. as a rule, at the inner diameter of the bearing. The clearance between bearing and shaft results arithmetically from the tolerances of bearing and shaft. The real starting clearance at commissioning is the difference between the measured actual inner diameter of the bearing and the […]
