These features support reliable torque transfer, smooth fan operation, and long-term gearbox durability.
- Double reduction right angle design supports demanding cooling tower fan drive applications.
- Two-stage reduction reduces motor input speed to efficient fan operating speed.
- Maximum gearbox capacity reaches 142 HP / 106 kW.
- Heavy-duty construction supports continuous industrial cooling tower operation.
- High thrust capacity handles downward vertical fan loads up to 5,400 lbs.
- Internal bearings offer an L10a life exceeding 100,000 hours.
- Rigid cast housing helps reduce gear deflection under operating loads.
- Sloped internal case floor improves structural rigidity and oil drainage.
- Accessible oil sight glasses, fill plugs, drainage ports, and vents simplify maintenance.
VFD applications require special lubrication protection below 450 RPM.
These specifications define the Model 1110 gearbox’s capacity, ratios, lubrication needs, and structural limits.
