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

August 4, 2023 3:07 pm

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

Frequent heavy dirt, dust, and swarf accumulation is common with pillow blocks and fixed flange bearings. This necessitates constant lubrication and maintenance. However, customers now have a solution with injection-moulded spherical insert bearings, which offer a maintenance-free and lubrication-free option for their metallic pillow blocks. Igus has expanded its range of high-performance polymer spherical balls for cost-effective sheet metal housings to enhance this offering further. These new components can be easily mounted in seconds and are readily available from stock. Additionally, igus has introduced dimensionally identical 1:1 replacements for pillow blocks and flange bearings, entirely made of wear-resistant plastic materials, including a high wear-resistant plastic ball and a heavy-duty plastic housing.

Metal and lubrication are found close together in mechanical engineering. igus proves that this can be different. 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. This additionally minimises the sealing and prevents unplanned machine downtime. The use of insert bearings is also suitable in agriculture, farming, the food industry, or plant and mechanical engineering. The igubal spherical insert bearing comes directly from injection moulding and is 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. If a complete polymer pillow block or flange bearing is required with polymer housing, then it is also available directly from stock. The Igubal spherical insert bearing has high durability, and its service life can be easily calculated online.

Lubrication-free operation due to iglidur J

The spherical insert bearings made of iglidur J are cost-effective. They also have a very low coefficient of friction in dry operation. The material absorbs only a little moisture, so using the spherical insert bearings is also suitable outdoors. Due to the high-performance plastic’s chemical resistance, the 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) and cast housings (UC204-210). It is also available as a complete polymer pillow block of flanged bearing sizes UC203-210 and F203-210.
