GRAPHALLOY Solves Bearing Seizures in Steel Mill

Bearing problems? One steel mill had them — and lots of them. Greased roller bearings in their guide rolls were seizing under high heat (170–180°C), causing maintenance headaches and production delays.

Their team turned to GRAPHALLOY® bushings, a graphite/metal alloy that doesn’t require grease and thrives in high temps. After six months with GRAPHALLOY in place, the plant manager gave a glowing review: “They’re performing very well.”

Now they’re upgrading all the guide rolls.

Proven reliability in high-temperature glass applications

Graphalloy® self-lubricating bearings perform where conventional bearings fail.

• 
  Operate up to 1000°F without grease
• Resist corrosion, dust, and contamination
• Extend service life and reduce downtime

In one glass application, Graphalloy cam followers lasted over 4× longer—saving more than $15,000 annually.

Geothermal Brine Pump Case Study

  

GRAPHALLOY® bushings replace failed metal and plastic bearings in extreme-temperature geothermal brine pumps, delivering long-term performance in one of the harshest environments on earth.

 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.

Graphalloy® “Can” Do It!

 In early January, a leading aluminum beer-can producer approached Graphalloy to upgrade the roller bearings in their heat-treating ovens. After installing our self-lubricating pillow block assemblies, they’ve enjoyed eight weeks of maintenance-free, grease-free operation with zero failures or contamination. Impressed by the results, they’ve requested a quote for 26 additional units to roll out the solution across their production line.
