Product Details:

GRAPHALLOY is combination of Graphite+Metal Alloy Formed From Graphite & Molten metal making a uniform, solid, self lubricating material widely used as a bushing material. popular configuration includes : cylindrical, splite, & flanged bushings, thrust washers, cam followers, pillow blocks, flang & hanger units.

GRAPHALLOY is made for high temperature applications where maintaining lubrication can be difficult, or even impossible.

This case history shows how the self-lubricating qualities of GRAPHALLOY -- with no grease or oil to burn up or collect dust and dirt -- can solve problems even under the harshest operating conditions.

Steel Mill Cooling Beds A tough, hot and dusty application

Think you have a tough, "rough service" application?

Consider this example from a Midwest steel mill.

As molten hot plates, bars and billets come off casters, they move on horizontal rollers typically supported by water cooled bearings. This particular mill was already using GRAPHALLOY bushings for the horizontal rollers in their cooling beds, and the bushings were thriving under these severe heat and water spray conditions.

Because of the success with the horizontal rollers, the mill wanted to consider GRAPHALLOY flange bearings for another application: the vertical guide rollers along the sides of the cooling beds.

These vertical guides keep the hot steel from running off the sides of the cooling beds. Guide rollers remain static until a piece of hot steel slams up against them, at which time they are expected to turn instantly to guide the steel back onto the cooling bed.

This mill had been using conventional greased rolling element bearings in the vertical guides, but these bearings usually lasted only a few months.

When considering the GRAPHALLOY flange unit upgrade, the customer was concerned about shock loading and flange breakage. Fortunately, neither of these turned out to be a problem. Based on the success with the vertical rollers, the mill has since retro-fitted additional lines with GRAPHALLOY.

This is an excellent example of how GRAPHALLOY can solve bearing problems under harsh and difficult operating environment.

Product Details:

GRAPHALLOY bushings are used in water, hydrocarbons, chemical and fuel oil pumps, meters, mixers, and rotary filters. GRAPHALLOY is also used for submerged bushings in cleaning fluids, weak acids, and alkalis. The textile dyeing and paper/pulp industries employ GRAPHALLOY bushing extensively. GRAPHALLOY is not soluble in most industrial liquids.

GRAPHALLOY is a preferred material for steam seals and for equipment that must be steam cleaned. No lubrication to wash away.

As Bushings or Seals in water pumps, gasoline pumps, spray pumps, meters, foot bearings, mixers, dye jigs, food and pharmaceutical equipment, bleaching and washing tanks, and rotary filters; even in molten metals.

Split Double Flange Bushings:

As with all GRAPHALLOY bushings, these split double flanged bushings will survive harsh environments. They are commonly used in screw or spiral conveyors or feeders to move a large variety of bulk materials. They are also used in batch mixers and in agitators. Since GRAPHALLOY never equires lubrication, the conveyed product is not contaminated and does not collect in the bearing.

Product Details:

The horizontal reactor shaft bushing supports the circulating impeller and internal mechanical seal in this continuous duty application. Although the combination of a low lubricity sealing fluid, intermittent slugs of concentrated sulfuric acid and high bearing load creates a trouble some environment for other bearing materials, self-lubricating graphalloy will provide superior performance. It resists the acid chemical attack. It does not deform under load and maintains a close running clearance. At one installation the graphalloy bushing had only .003" wear after four years of operation.

Product Details:

Graphalloy bearings are key ingredients for minimal maintenance and uninterrupted production in food contact equipment:

• Available in FDA accepted grades
• Self-lubricating; works without external lubrication
• Operate in extreme temperatures (-450° F to +750° F/-240° C to +400° C)
• Avoid loss of lubricant in steam/pressure washes
• Contain no oil or grease
• Can be immersed in liquids without contaminating food production
• Operate submerged in low viscosity and corrosive liquids

High heat applications challenge the life and durability of conventional bearings. In cold, wet environments, bearings often cannot hold lubrication. Use of Graphalloy bearings can solve these problems and, as a result, reduce downtime and lost production.

An excerpt from Industrial Maintenance & Plant Operation DS 2175-12A
When Wausau Paper Mills Co. Jay ME suffered repeated failures of the original bronze bearings furnished with the equipment, the maintenance staff switched to graphite-metal alloy bearings. The move was made to GRAPHALLOY self-lubricating bushings designed specifically to withstand the intermittent dry-run conditions of the paper mill's stock tank agitators, where varying stock levels sometimes eliminate all lubrication.
The mill uses 15 pulp stock agitators to produce manufacturing papers and labels. Each unit has a horizontal shaft driving a 54 inch, 4 blade shockless propeller made of stainless steel. The original bushings were made of bronze and had graphite plugs that were expected to provide self lubricating properties.
One of the GRAPHALLOY Bushings was installed in January 1996. During the plant's July shut down, this bushing was inspected and showed no wear. At the January 1997 inspection, again the bushing showed no wear. In February 1997, eight additional GRAPHALLOY bushings were ordered and the new bushings were installed on all remaining agitators. As of January 1998, the bushings were still operating well and no measurable wear was apparent on those installed 18 and 24 months prior.
Mill management expects to save at least $40,000 per year by reducing purchases of replacement parts and the labor required for replacement of the previous bushings. Additional benefits are expected by freeing up maintenance staff who previously spent a significant portion of their time addressing the agitator problems

High Temperature Bearings Deliver Savings of More than $10,000 in Pulp and Paper Industry:GRAPHALLOY has delivered over $10,000 in savings per year for one pulp mill. The lime kiln conveyor, operating at more than 650degree F (343degree C) had bearing failures every few months.
As a result, maintenance costs were rising and production was declining. The use of GRAPHALLOY Bearings eliminated the additional maintenance and increased productivity.

 GRAPHALLOY High Temperature Bearings Solve Problems in Bakery Ovens:
A division of a large food manufacturer specializing in frozen pizza was experiencing difficulties with the operation of their bakery ovens. The conventional oil-lubricated bearings being used in the ovens were lasting only one week. The customer had been replacing 16 to 20 burned-out bearings every seven days for over one year.
GRAPHALLOY high temperature bearings were installed. Many months later, these bearings did not show any signs of wear.

Glass Manufacturer Saves Over $20,000 with GRAPHALLOY High Temperature Bearings:
high temperature bearings for glass cook tops For this glass cook top manufacturer, cam followers were failing on a conveyor that traveled through an oven at more than 600degreeF (316degreeC). The high temperature grease lubricant being used was inadequate. Maintenance costs were high at $100 per hour.
Once GRAPHALLOY Cam Followers were installed, the manufacturer realized a savings in maintenance costs of over $20,000 per year

Product Details:

The interior temperature of an annealing furnace is in the range of 1200F. Even though bearings supporting the pinch rolls are outside the walls, they still reach temperatures up to 7500F and yet must be able to compensate for shaft expansion from cold startup to production temperature levels. Rigid, grease lubricated rolling element bearings could not meet these conditions, so the operators specified GRAPHALLOY journal sleeve bushings sized for installation in a special metal shell and inserted into the existing housing. Since 1990 the design has been operating successfully in this tortuous environment.
