HIGH TEMPERATURE BUSHINGS & THRUST WASHERS


STANDARD BUSHINGS

For Temperatures to 750^o F

GRAPHALLOY High Temperature Bushings are intrinsically suitable for heavy industrial applications. Up to 750^oF, installations of these bushings have operated more than ten years without interuption and without replacement of shaft or bushings.

In normal applications, shafts are cold-rolled steel or cast iron. However, for longer life and even higher load capacity, shafts should be of carbon steel, ground and polished to a 16-micro inch finish and with a hardness of 55 - 60 R/c

GRAPHALLOY Bushings are self-lubricating with low and constant coefficient of friction, and are long lived. They excel where many other types of bearing fail. Examples: where oil or grease cannot be used; quick starts and stops under load-GRAPHALLOY will not cold flow or weld under load; and quick, short linear or rotationg movements. (Some of our customers use these bushings for conducting electrical current).

STANDARD THRUST WASHERS

Temperatures to 750^o F

GRAPHALLOY High Temperature Thrust Washers are used in conjunction with conveyor bushings, traction wheel bushins, pillow blocks and similar installations where thrust is involved. Such a thrust washer should always be used with a steel mating face that has an equal or larger O.D. than the thrust washer.

Successful applications occur where a cold-rolled steel mating face has a 32 microinch finish. For best results, however, the mating face should be ground and polished to a 16 - microinch finish and should have a hardness of 55 - 60 R/c.

Steel set-collars with smooth thrust faces are used to hold shafts in position axially. These are used in conjunction either with a GRAPHALLOY Bushing or a GRAPHALLOY Thrust Washer.
