DYNAMIC AND ENGINEERING DATA

Hubs can be combined three ways:

1. Hub A with Hub A
2. Hub A with Hub B
3. Hub B with Hub B

Design Characteristics

Operating Temperature -40ºF to 212ºF
Short Duration Maximum Temperature 250ºF
Polyurethane spiders available in four hardness levels:

80 Shore A - Torsionally Soft, Blue
92 Shore A - Standard, White
98 Shore A - Torsionally Stiff, Red
64 Shore D - Torsionally Stiff, Green (Available upon request, yields 25% more torque then 98A version)

Resistant to oils, grease and many solvents. Good atmospheric and chemical resistance. Excellent shock and vibration dampening properties. Hub jaws have unique concave pocket, that eliminates edge pressures and allows prolonged wear resistance of the elastometric spider. Hubs supplied in materials shown below are furnished with standard or metric bore with keyway and setscrew unless otherwise specified. Options include tapered bores, SAE splines, cross bolt/clamping style and other customizations to meet your individual requirements.

MATERIAL: ALUMINUM

| MATERIAL: SINTERED STEEL

| MATERIAL: CAST IRON

Design Characteristics Series F design is made specifically for internal combustion engine drives. Flanges can be modified to be bolted directly to flywheel or pulley sheave. Excellent for driving hydraulic pumps, compressors, low inertia generator sets, gear boxes, centrifuges, etc. Same dynamic ratings as shaft to shaft design-no maintenance or lubrication required.
