Hansen M4KB Bevel-Helical Industrial Gearbox
The Hansen M4KB is a line of heavy-duty bevel-helical (right-angle) industrial gearboxes engineered for demanding industrial applications requiring high torque transmission capability, absolute reliability, and optimized thermal performance. As part of the prestigious Hansen M4 / P4 product family, the M4KB model combines high-precision spiral bevel gear sets with high-quality helical gears, delivering smooth operation, extremely low energy losses, and long service life. Its robust casing construction and superior heat dissipation design allow the Hansen M4KB to operate stably in harsh environments such as cooling towers, mining conveyors, chemical agitators, cement/clay mills, and wastewater treatment plants.

Legacy Hansen Gearbox Replacement & Equivalent Upgrade Guide
Worn or damaged older generation Hansen gearboxes or other industrial gearbox brands can be directly replaced with equivalent Hansen M4KB / P4 models. Refer to the replacement cross-reference table below:
| Legacy Model / Brand | Shaft Layout Type | Equivalent Hansen M4KB Model | Torque / Power | Fit & Mounting Engineering Notes |
|---|---|---|---|---|
| Legacy Hansen Powerkwik / HPP | Right-Angle Bevel Shaft | Hansen M4KB10 / M4KB11 Standard Replacement | Equivalent / 15% Higher | Matching center height and foot mounting; check output shaft diameter. |
| Flender B3SH / B4SH Series | Right-Angle 3 or 4-Stage | Hansen M4KB12 / M4KB13 1-to-1 Equivalent | Equivalent load capacity | Foot mounting hole spacing compatible; cooling fan position similar. |
| SEW Industrial M3AR / MC3RL | Industrial Right-Angle | Hansen M4KB14 / M4KB15 Replacement Upgrade | Higher thermal capacity | Hansen thermal design reduces the need for external oil cooling systems. |
| Legacy Hansen M3RL / M3RD | Older Hansen M3 Generation | Hansen M4KB16 / M4KB17 M4 Upgrade | Higher rated torque | Improved seal system against oil leaks and more rigid casing. |
