Heavy Equipment Market

Spauldite^® composite bearing materials have replaced metallic bearing materials in many demanding heavy-equipment applications over the last 30 years. The unique properties of Spauldite^® bearing materials make them ideally suited for use in heavy-equipment applications, such as axle-pinion bearings in front-end loaders and tandem-axle articulation pivots in road graders. Spaulding heavy-equipment bearings are used by the world's leading heavy-equipment manufacturers.

Features and Benefits

Weight savings of greater than 5:1 over metallic bearings allow for reduced weight and greater payload.

Improved impact absorption reduces shock transmission through chassis and drive-train components.

Reduction or elimination of routine lubrication reduces routine maintenance costs for your customers.

High tolerance for contaminants makes Spauldite^® bearings the right match for heavy-equipment operating in tough, dirty environments.

Spauldite^® bearings are available in widths up to 48 inches. Inside diameters as small as .25 inches and as large as 18 inches are possible.

Spauldite^® bearing materials are easily turned, milled or drilled.

Grades

T-601 Sheet: Spauldite^® bearing material is a medium-weight cotton reinforcement with a special resin matrix that provides limited self-lubricating performance. Sheet form is widely used for flat components such as thrust washers, wear blocks, guides and machine components such as spur gears.

Density:	1.38 g/cc
Rockwell Hardness	104 M
Flexural Strength:
LW	24,000 PSI
CW	20,000 PSI
Izod Impact
LW	2.6 ft x lb / inch
CW	2.6 ft x lb / inch
Compression Strength:	35,000 PSI
Water Absorption:	.62% (.125 inch thick)

T-601 Tube: Spauldite^® bearing material is a medium-weight cotton reinforcement with a special resin matrix that provides limited self-lubricating performance. Spauldite^® tubes are convolute-wound, meaning that the reinforcement runs in the axial and circumferential direction. This construction provides high strength in the hoop or circumferential direction. Tube form is readily machined into various components such as bushings and guides.

Density:	1. 25 g/cc
Compression Strength:	20,000 PSI
Water Absorption:	1.36% (.125 inch thick)

T-602 Sheet: Spauldite^® bearing material is a medium-weight cotton reinforcement with a special resin matrix and graphite lubricant uniformly distributed throughout the material providing increased lubricity. Sheet form is widely used for flat components such as thrust washers, wear blocks, guides and machine components such as spur gears.

Density:	1.38 g/cc
Rockwell Hardness	105 M
Flexural Strength:
LW	22,000 PSI
CW	21,000 PSI
Izod Impact
LW	2.4 ft x lb / inch
CW	2.0 ft x lb / inch
Compression Strength:	35,000 PSI
Water Absorption:	.71% (.153 inch thick)
Load rating as follows:
Maximum Pressure:	2500 PSI
Maximum Velocity:	2500 Feet per minute
Maximum Pressure x Velocity product:	15,000 PSI x Ft / min

Note: In some applications, T-602 sheet may be thermally formed into thin- walled split-bearing applications.

T-602 Tube: Spauldite^® bearing material is a medium-weight cotton reinforcement with a special resin matrix and graphite lubricant uniformly distributed throughout the material providing increased lubricity. Spauldite^® tubes are convolute-wound, meaning that the reinforcement runs in the axial and circumferential direction. This construction provides high strength in the hoop or circumferential direction. Tube form is readily machined into various components such as bushings and guides.

Density:	1. 25 g/cc
Compression Strength:	20,000 PSI
Water Absorption:	1.6% (.125 inch thick)

T-791: Spauldite^® bearing material is a medium-weight cotton reinforcement with a special resin matrix that provides inherent self-lubricating performance. Similar to T-601, this grade is specially formulated to allow thermal forming into round cross-sections. It is widely used in thin wall split bearings.

Density:	1.38 g/cc
Rockwell Hardness	107 M
Flexural Strength:
LW	22,000 PSI
CW	19,500 PSI
Izod Impact
LW	2.2 ft x lb / inch
CW	1.9 ft x lb / inch
Compression Strength:	35,000 PSI
Water Absorption:	.72% (.153 inch thick)
