GRAPHALLOY® self-lubricating bearings have proven their value in some of the toughest food processing environments. In one potato chip fryer application, GRAPHALLOY pillow blocks on the paddle wheel drive shaft ran continuously for over six years at 375°F — without grease, without failure, and without downtime. By eliminating lubrication needs and resisting both heat and caustic washdowns, these bearings delivered reliability that standard greased bearings couldn’t match. Today, the snack producer considers GRAPHALLOY standard equipment across their facility.

GRAPHALLOY® Bearings From Frequent Failures to Four Years of Reliability in Snack Food Fryers

 In their continuous fryer systems, manufactured by Heat & Control®, this producer faced recurring failures with greased ball bearings. Bearings used on belts and paddles in the fryers experienced extreme conditions:

• Exposure to 400°F
• Continuous splashing with hot oil
• Full submersion in cooking oil for certain locations

Despite regular re-greasing, the bearings on the hold-down belt had to be replaced every 3 to 4 months. Maintenance was costly, and unplanned downtime was disruptive.
