Case Study: Band Cutter Linear Guides in a Dough Machine
Technical Challenge
A bakery was experiencing continual failures of their band cutter linear guides, which were not holding up to the required performance standards. The linear guides required replacement every 3 weeks, causing excessive maintenance, downtime and lost production.
NSK NH/NS Series Linear Guides
NSK Solution
NSK proposed high-speed stainless steel linear guides, with food-grade K1 lubrication units. Although the new linear guides were double the cost of the original Armoloy-coated units, the service life improved ten-fold, increasing output and decreasing downtime, with a total cost savings of $219,924.
