Shock loads and contamination make crushing equipment one of the toughest kinds of equipment for precision components, particularly bearings. Keeping machine availability high and total cost of ownership low in these harsh conditions requires specialized engineering and materials knowledge.
Timken AP bearings handle the crushing loads from the breaker shafts in crushing equipment, while Timken spherical roller bearing solid-block housed units and feeder breaker chain help ensure conveyor systems keep moving. Timken engineers have the know-how to help customers’ equipment handle heavy shock loads, along with contamination and lubrication challenges.
When a few of a customer’s plants ran more power through their Lippmann- Milwaukee, Inc. crushers, something had to give. Users of the Lippmann- Milwaukee 4248 and 3862 models pushed their jaw crushers beyond specification limits, resulting in premature damage of the frame bearings. Working together, Timken and Lippmann-Milwaukee engineers conducted root cause analysis and discovered the increased speeds created a low lubrication film that, when paired with the shock loads, damaged the bearings.
Timken应用工程师将与Lippmann-Milwaukee一起收集的数据，并建议一种解决方案，以适应当前的破碎机设计和设备上的真实需求。
They solved the problem by applying a Timken engineered surface to the rollers of Timken tapered roller bearings. The deployed units immediately displayed a marked improvement in service hours. The results convinced Lippmann- Milwaukee to specify Timken tapered roller bearings with engineered surfaces as standard for these equipment models.
