The 2-arm universal puller 20-AV with adjustable clamping depth for pulling off bearings, gears and washers

Series 20-AV

Down Arrow
2-arm universal puller with sliding, always parallel Pulling hooks

Description

The 2-arm universal puller with adjustable clamping depth is used to pull bearings, gears and discs in all standard sizes for trades, workshops and industry. The 20-5 is the largest of its kind in the world and therefore the most powerful puller in the 20 series. It can be used to remove any component that sits on a shaft and is freely accessible from the outside. Thanks to its individually adjustable clamping width and depth, the puller adapts to any pulling situation and guarantees particularly safe, non-destructive removal both on external removal and internal extraction.

Area of application

  • For extracting bearings, gears and discs in all standard sizes for trade, workshop and industry.

Benefits Operation

  • Screw connection enables easy loosening and particularly tight fastening of the pulling hooks with a hexagon wrench

  • Easy application also with eccentric components due to free-moving pulling hooks sliding off the crossbar

  • Variable adjustment to any span between 0 mm - 750 mm and span depth between 500 mm - 750 mm

  • Secure positioning of the spindle thanks to the rotatable spindle tip, both on smooth surfaces and when centring (Switch Technology)

  • Optionally convertible from an external extractor to an internal extractor by reversing the pulling hooks

  • Anti-slip guard on the spindle head for safe working with wrench

  • Spindle riser protects the threading

  • Attach the Pulling hook to the part to be extracted from the outside
  • Slide the claws under the component
  • Use a spanner to fasten the hooks
  • Pull the spindle manually under pressure to fix it
  • Use a ratchet or combination spanner to move the hexagon on the spindle head until the component is released
