Bearings, whether rolling or plain, normally have to be pressed onto shafts
 Problem: . They also have to be pressed on from one end, unless split. Split bearings have the disadvantage of having to be fully contained in some way in order to maintain integrity, as well as introducing two cracks, parallel to the shaft axis, to accumulate debris and act as preferred wear sites.
Solution: Igus has introduced a new version of their M250 clip bearings. Matthew Aldridge of Igus UK recently showed Eureka how the Clip2 clip has only one diagonal split, and is made of low Youngs Modulus material so it can be opened out sufficiently to allow it to be put onto a shaft from the side. Its design inherently accommodates thermal expansion.
Made of 'iglidur' it is available ex stock from igus UK in sizes 4 to 25mm. The company claims it has very low clearance, precision fit, and a high load capacity. Depending on the application, the clip bearing can also be made at short notice from any of the other 21 igus materials.
Applications: Exising customers in the UK range from agricultural machinery manufacturers through to high tech applications in the automotive industry. The bearings can be used wherever the benefits of the company's solid state polymer lubrication and maintenance free, corrosion resistance, and light weight properties are required. TS
