Introduction

A British producer of hygienic wet wipes for domestic and cosmetic use was experiencing frequent failures of linear guides used on the ‘Stacker Line’, which is used to compress wet wipes for packaging. NSK’s engineering team visited the site and reviewed the application. This process revealed that the existing linear guides were frequently failing due to corrosion and the ingress of chemical fluid, causing seizure from grease washout and corrosion inside the linear slider. Following the review, the engineers recommended to replace the standard linear guides with NSK linear guides featuring stainless steel sliders and specially coated rails. Since the implementation, breakdown events have been reduced significantly. Whereas the plant was previously experiencing 26 breakdowns a year, the company has witnessed just three in 12 months using the NSK linear guides – an impressive 88% decrease. In turn, the company has achieved significant savings in linear guide, downtime and repair costs.
