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 […]
In standard cases, we have had very good experience with superglues (e.g. Loctite 401). In the case of materials like iglidur J that are difficult to glue, considerably better results are achieved with 2-component systems (for example Loctite 406 + Primer 770). For applications involving high temperatures, we have had good experience with epoxy resin […]
In the words of Kermit the frog: “It ain’t easy being green”. And even though he is only a hand puppet, Kermit is right – Today, many companies are doing everything they can to reduce their carbon footprint. However, transformation into a more environment-friendly company does not happen overnight. This is normally the culmination of […]
1. Cost points of view Cost reduction is an important factor for most companies. The possibility of using a cost-effective shaft material primarily depends on what bearing is selected. For example, ball bearings require very hard (60HRC or higher) and smooth shafts. The same applies to bronze bearings: the shaft must be harder than the […]
