Model Type 453 -High Temperature Bearings
GRAPHALLOY® Type 453 high temperature bearings are self-lubricating, contain no oil and provide long service life in high temperature applications. Suitable high temperature applications include industrial ovens, conveyors, overhead paint lines, valves, furnaces, louvers and trolley wheels. These sizes also fit many common overhead paint line conveyors. Self-lubricating GRAPHALLOY eliminates time consuming and costly maintenance. GRAPHALLOY survives hostile environments and high temperature applications with capabilities of +1000°F and more! Type 553 high temperature thrust washers are used with Type 453 high temperature bushings in many conveyor applications. Dimensions below are in inches. Metric and custom sizes are also available. To determine which grade (XXX) is right for your application, please contact one of our engineers at sales@graphalloy.com or 914-968-8400.
GRAPHALLOY®, a graphite/metal alloy, is a unique self-lubricating bearing material that offers superior performance in hundreds of mechanical and electrical applications.
GRAPHALLOY standard and custom designed products provide lifetime cost savings and significant operating advantages over conventional bushings and bearings.
Features: Benefits
Self-Lubricating: Requires no grease or oil. Permits continuous operation and eliminates downtime.
Hot: Works at high temperatures where oil-based lubricants burn off or oxidize and plastics fail. Operating temperatures to 1,500º F / 800º C (in non-oxidizing atmospheres). Will not gum or seize.
Cold: Does not congeal or solidify at low temperatures or cryogenic conditions. Maintains self-lubrication.
Dry: Works without lubrication. Survives run dry applications. Eliminates galling or seizing in hot and dry conditions. Will not attract dust.
Wet: Operates submerged. Will not swell or wash out. Withstands a wide variety of hostile fluids.
Dimensionally stable: Does not cold flow or deform under pressure. Maintains its size and shape.
Chemically Resistant: Insoluble in most industrial liquids. Works in acids, alkalies, hydrocarbons, water, and liquid gases.
Low Coefficient of Friction: Constant, low coefficient of friction. Not just a surface layer, solid throughout.
Linear Motion: Maintains lubrication during linear motion. Lubrication is not drawn out and dust is not pulled in.
Current Conducting: Eliminates sparks and static. Conducts well.
Corrosion Resistant: GRAPHALLOY Bushings resist attack by most corrosive liquids and gases such as sulfuric acid, hydrochloric acid, chlorine water, and caustics. Graphalloy bushings also perform well in submerged or washdown applications. A thin layer of GRAPHALLOY deposited on the shaft inhibits corrosion of the shaft.
FDA Accepted: Accepted for food services. No lubrication to drip or cleanup. Easily steam cleaned.
