NRG's
non-metallic H78 shear pin sprockets do not rust
or seize like metallic drive sprockets are prone to do. Lightweight
and easy to assemble, these drive sprockets have a strong lubricated
green nylon shear pin hub and replaceable UHMW-PE or Nylon-6 bolt-on
sprocket teeth. Steel shear pins can be provided and sized for torque
requirements. To be used in conjunction with NRG NMH78 drive chain
and driven sprockets, NRG's H78 drive sprockets prevent damage to
the collector chain and flights during overload conditions. Also available
in trip cam design, jaw clutch design, and cast iron construction
options. Contact your local NRG
representative for more information. |
