A competitor’s mounted ball bearings were failing during the production season resulting in costly unplanned downtime. The customer was using a nickel-plated cast iron housing with thin dense chrome plated insert bearings. The dumping action from the hopper caused a high shock load and some housings would crack under the load. Then, the nickel would flake or peel off the cast iron and get into the processed corn. Additionally, some bearings would seize or lock up.
Sealmaster® Solution
After review of the application, we selected a Sealmaster PN Gold mounted ball bearing with a high strength passivated 316 stainless steel housing. The Sealmaster bearing’s stainless steel housing has superior strength to a nickel-plated cast iron and does not flake like nickel-plated cast iron. The high performance triple lip seal outperformed the competitive seal and the customer decided to use the Reduced Maintenance version to eliminate the cost of relubrication.
After testing, the Sealmaster PN Gold mounted ball bearing lasted three seasons.
