NTN’s Sentinel™ Series Churns Through Downtime on Dough Mixer

Success Report: Sentinel™ Series Ball Bearings

ntn sentinel web

A producer of frozen, precooked, and dried pasta products was experiencing weekly bearing failures on its dough mixer due to the frequent washdowns required in the production area. The recurring failures were resulting in over $5,500 in lost production each week. NTN’s engineering and sales support team performed a thorough evaluation of the mixer and determined the failures were being caused by grease washout that occurred during the regular equipment washdowns.

The NTN Solution

NTN’s team recommended that the bearings being used in the mixer be replaced with our Sentinel Series ball bearings. Our Sentinel Series features corrosion-resistant stainless steel ball bearings with seals and NSF H1 registered solid lubricant. The solid lubrication provides up to 21 times better washout resistance than standard grease and the seals provide improved protection over standard deep groove ball bearings, which is critical to extending the life of equipment exposed to moisture.

The Result

The NTN solution lasted over six months, cutting yearly bearing failures by 2,300%. The increased uptime, reduced maintenance, and decrease in bearing spend resulted in $320,000 in annualized savings for the customer.
