Posired Advanced high thermal capacity gearboxes: Ideal for the extreme requirements in the bulk material handling and the mining industries. The series exhibits outstanding mechanical performance and increased thermal capacity, allowing users the capability of opting for smaller-sized gearboxes than normally required.

What sets the range apart is the modular thermal system, which helps the gearboxes provide increased thermal performance and higher mechanical efficiency. Features include an axial cooling fan, with higher flow rate for better cooling of the gearbox and an advanced lubrication system. The integrated mechanical oil pump improves bearing life and increase thermal capacity.

Oil change periods have been increased up to 7,500 hours, with up to 15,000 hours for synthetic oils. The seals are contactless in both input and output for greater efficiencies and improved heat capacity. The cover plates have active cooling fins on both sides and the top of the housing for better air-cooling. The finned covers provide an expanded surface area and include integrated oil pipes for bearing lubrication.

Gear teeth have been optimised to provide higher torques, with less power dissipation, to improve thermal capacity.
