Maintenance free igubal spherical insert bearing in combination with metal or polymer pillow blocks


Lubrication-free igus spherical balls are available with cost-effective sheet metal housing, polymer housing or a cast iron housing

Heavy dirt accumulation, dust and swarf are commonplace for pillow blocks and fixed flange bearings. Constant lubrication and maintenance are therefore necessary. With the injection-moulded spherical insert bearing, customers can resort to a lubrication-free and maintenance-free solution for their metallic pillow blocks. igus has now extended this range of spherical balls made of the high-performance polymers specifically for cost-effective sheet metal housings, these can be mounted in seconds. The complete solution is available directly from stock. Igus also developed dimensionally 1:1 replaceable pillow blocks and flange bearings completely in plastic i.e. high wear resistant plastic ball and heavy-duty plastic housing

Metal and lubrication are found close together in mechanical engineering. igus proves that this does not always have to be the case. The motion plastics specialist has developed its igubal exchangeable spherical insert bearing especially for pillow blocks and fixed flange bearings with metallic housings. These consist of the high-performance polymer iglidur J, which reduces costs since lubrication and maintenance are eliminated. The use of polymers prevents dirt and dust from settling in the bearing, which additionally reduces the sealing and prevents an unplanned machine downtime. The use of insert bearings is also suitable in agriculture and farming, in the food industry or in plant and mechanical engineering. The igubal spherical insert bearing come directly from injection moulding and are therefore cost-effective. Within a few seconds, they can be mounted in place of ball bearings in existing classic metallic pillow blocks and flange bearing housings and now also in low-cost sheet metal housings. In case a complete polymer pillow block or flange bearing is required with polymer housing, then it is available too, directly from stock. The Igubal spherical insert bearing has a high durability and its service life can be easily calculated online.

Lubrication-free operation thanks to iglidur J

The spherical insert bearings made of iglidur J are not only cost-effective, but also have a very low coefficient of friction in dry operation. The material absorbs only a little moisture, so that the use of the spherical insert bearings is also suitable for outdoors. Due to the chemical resistance of the high-performance plastic, the use of exchangeable spherical insert bearing is also suitable for use in chemically demanding applications such as agricultural technology or even glass processing. iglidur J displays its advantages especially in soft shafts. The igubal spherical insert bearings are currently available in five dimensions for low-cost sheet metal housings (Ø 17mm, 20mm, 25mm, 30mm and 35 mm) as well as for cast housings (UC204-210). It is also available as complete polymer pillow block of flanged bearing in sizes UC203-210 and F203-210
