Self-lubricating xiros® plastic ball bearings used in labeling machines

With the Sleevematic labeling machine, labels are cut from the roll one at a time and then attached to the bottles. Once a roll of labels is depleted, it needs to be replaced by a new one without stopping the entire plant. Here the so-called "buffer conveyor" is used as a film storage, in which Krones employs xiros® plastic guide rollers from igus®.

What was needed: Uninterrupted flow in the bottling process
Requirements: Smooth running of the ball bearings, no need for external lubricants, no maintenance
Material: xiros® B180
Industry: Beverages sector
Success for the customer: Guide rollers from igus® ensure a reliable service with excellent coefficients of wear and friction without interrupting the process.

Problem

In the past, Krones AG relied on conventional metallic ball bearings, but these did not run smoothly enough and were too heavy. In addition, the rollers stopped sometimes and the label tape could not be attached correctly on the bottle. Downtimes increased, resulting in additional costs. The problem was in finding lightweight and maintenance-free ball bearing solutions that could ensure smooth running in the guide rollers.

Solution

Due to the decisive advantage of the smooth running, the xiros® guide rollers from igus® were approved. Depending on the size of the film storage device of the Sleevematic labeling machine, between 12 and 36 guide rollers are used. Two xiros® fixed flange ball bearings are used per guide roller. Due to the low mass, the freedom from maintenance and the best coefficients of friction and wear of the plastic solution, the problems with metallic ball bearings have become a thing of the past.
