Success Story
Industry: Food & Beverage
Application: Barrel Washer
Cost Savings: € 56 600
Introduction
A producer of machine for vegetable treatment was experiencing problems on its barrel washers. With the rotation of the washer drum, bearings were under water once per rotation. Due to water washout and corrosion, it was necessary to replace the bearings installed every 3 months. This involved high costs. NSK engineers investigated the problem and offered Triple-Lip Sealed Bearings. This solution resulted in a significant lifetime extension to more than 7 months.
