FRP90 Helicals gearboxes for feeding systems

The gearbox FRP90 is expressly designed to be fitted on pick-up boots for feeding systems screw conveyors; the gearbox/boot fitting does not comply with any standard and a wide range of fitting is offered to match the customer’s need.

The one-piece aluminium die-cast body is abundantly sized to avoid any harmful vabration to the feeeding system and to withstand heavy operations.

Helical gears – made of alloy steel, case-hardened, tempered and shaved – are designed and verified according to ISO 6336 and DIN 3990. Bearings are calculated for at least 15,000 running hour average lifetime. Keyways according to DIN 6884.

The gearboxes are delivered filled with synthetic long-life oil (without plugs), in the appropriate quantity to install them in any mounting position without any prior specifi-cation.
