Packaging equipment

Background

The company manufacturers packaging equipment for the food and pet industries, which handle flour, sugar and various types of pet food. The machines operate 24/7 and are expected to last 20 to 30 years.

Requirements

The customer needed an oil-free linear bearing to facilitate the movement of guide rods used in the machine’s trimming and pressing stations. The bearing must have the ability to handle high loads and high cycles, while at the same time remaining unaffected by the excessive flour and sugar dust given off by the machines.

drylin® R linear bearings are dry running and do not contaminate the food items or become clogged with flour and sugar excess like other types of bearings that require constant lubrication. Their corrosion-resistant and maintenance-free features have also helped to reduce downtime and repair costs.

The packaging machines also use a new type of hybrid linear bearing from igus®. drylin® WJRM features a combined rolling-and-sliding carriage for reduced friction and can reduce the drive force necessary to power an application by a factor of four or five. The hybrid linear bearings are used on the machine’s bag magazines, which hold packages open as they are being filled with flour, sugar or pet food. drylin® WJRM bearings act as a mobile arm behind the bag to prevent it from falling backwards and spilling its contents. drylin® WJRM is also dry running and does not require messy lubricants.
