Introduction
BN Gears is best known for excavator final drives, but the same planetary gear technology powers a much wider range of machines — bulldozers, rotary drilling rigs, trench cutters, hydraulic grabs, hammer drills, and road rollers. When a travel or swing reducer fails on these machines, the sourcing problem is the same: find a reliable aftermarket unit fast.
This guide covers the non-excavator applications BN Gears supports.
Bulldozer Travel Gearboxes
Bulldozer final drives work under extreme shock loads and continuous track operation. BN Gears supplies travel reducers and components for dozer applications, built to the same case-hardened standards as the excavator line.
Rotary drilling rigs (piling and foundation machines) use heavy-duty reduction gearboxes for rotation and crowd drives. These are some of the highest-torque reducers in the industry, and BN Gears manufactures them with controlled heat treatment and full assembly testing.
Every BN Gears reducer — excavator, dozer, drilling rig, or trench cutter — shares the same core engineering:
Case-hardened forged alloy steel planetary gears
Controlled heat treatment for consistent metallurgy
Dual-cone floating seals for the harshest environments
ISO 9001:2015 certified manufacturing since 2000
Custom Development on Request
If your machine's gearbox is not in the standard catalog, the BN Gears engineering team evaluates compatibility and can develop new fits on request — from a single component to a complete assembly.
