GRAPHALLOY® 453 High Temperature Bushings

Graphite Metallizing Corporation has announced the availability of additional sizes of the GRAPHALLOY® 453 family of self-lubricating bushings. GRAPHALLOY® 453 Bushings are intended for use in severe industrial applications where temperatures reach 750°F (400°C) or higher. GRAPHALLOY® graphite/metal alloy bushings are designed to operate without lubrication.

GRAPHALLOY® 453 Bushings have proven to be successful in a variety of high temperature applications including bakery ovens, heat treat ovens, furnaces, conveyors, overhead paint lines, glass lehrs, louvers, dampers, valves as well as other environments where oil and grease cannot be used. Applications can experience improved performance through the use of GRAPHALLOY® materials.

Among their many advantages, GRAPHALLOY® bushings operate at longer intervals without the need for maintenance, which reduces costly downtime. They are an excellent choice for applications where service and maintenance tasks are cumbersome or difficult to perform. Additional benefits of GRAPHALLOY® include a low coefficient of friction and dimensional stability.

GRAPHALLOY® 453 bushings, like all GRAPHALLOY® products, do not soften at high temperatures or extrude under load. Installations of these bushings have operated for more than 10 years without maintenance. GRAPHALLOY® 453 Bushings are a proven solution for even the most challenging plant maintenance problems and new equipment designs.

Zero-Max ETP Shaft Locking Bushings

Plymouth, MN – ETP Shaft locking bushings from Zero-Max produce accurate and concentric mounting compared to mechanical shaft locking bushings.

ETP bushings incorporate a double walled sleeve encapsulating a pressure medium. When the actuation screw is tightened it forces the inner and outer wall of the bushing to expand uniformly against the shaft and hub of the mounted component. The result is concentricity to .001” T.I.R. Mechanical devices, by comparison, rely on precise and accurate tightening of the actuation screws to avoid excessive T.I.R. Additionally, extremely high compressive forces are imparted on the shaft by mechanical bushings.

ETP bushings are ideal where repeated mounting and dismantling of components is required. ETP Bushings are consistently accurate and easy to use.

The ETP Classic has flange mounted actuation screws. The ETP Express has just one mounting screw positioned in a radial location. The single actuation screw of the ETP Express is the fastest and easiest way to mount components accurately. The single actuation screw saves space, time and is easy to access.

Both ETP Classic and ETP Express operate in temperature ranges from -22° to 180° F. The ETP Classic handles torque ranges from 40 to 11,413 ft lbs while the ETP Express handles torque ranges from 40 to 6,400 ft lbs. Both require no lubrication. They are available in a full range of inch and metric sizes in both standard steel and stainless steel.
