Demanding hygienic requirements are posed by approval authorities for machine components used in the food and packaging industry. igus has now developed a ball-mounted pillow block bearing made of the FDA-compliant high-performance plastic xirodur B180. Compared to metallic solutions, the user is said to save 83% of weight with the smooth-running compact xiros bearing. Due to the same dimensions in the hole spacing, a 1:1 replacement is quick and easy.

Pillow block bearings play a central role in the food industry on roller conveyors or conveyor belts. Metallic pillow block bearings have high friction due to their shield and grease filling. This means that, for example, when they wear out the rollers of a conveyor belt no longer rotate, resulting in machine shutdown and high downtime costs. Maintenance of bearings with lubricant takes additional time. The use of lubricants and corrodible metal do not meet the hygienic requirements of the food industry.

Ball-mounted pillow block bearings made from xirodur B180 plastic are a lubrication-free solution with FDA-compliant components. Due to its special material and the built-in stainless steel balls, the bearing is smooth and corrosion-resistant.

The ball-mounted xiros pillow block bearing is flushable and suitable for application environments of up to 80°C. Capable of coping with high stress, the bearing withstands up to 50 kg with up to 850 rpm. The bearings are currently used by igus for shafts with a diameter of 25 mm. Other sizes are available upon request.
