Newly Re-designed P-Series Gearbox improves Backlash, Corrosion Resistance and Center Distance between Input and Outputs! 

High Ratio Heavy Duty Gear Reducers

Heavy Duty Gear Reducers

BLN Series heavy-duty right-angle gear reducers are built to handle the most demanding power transfer applications. Durable machined aluminum housings, hardened steel gears, and permanent lubrication ensure years of worry-free service. Designed for high efficiency, high torque output with minimal backlash, they provide outstanding performance in any application.

With six different BLN models, each available in four different reduction ratios and with input shafts ranging from 5mm to 25mm, it’s easy to find the right heavy-duty gear reducer for your needs. BLN right angle gear reducers provide up to 128Nm output at 1,000 RPM (varies by model). We have a broad selection of Misalignment Shaft Couplings in inch and metric bore sizes. Inch and metric Precision Ground Shafts are available from stock. 


Custom Heavy Duty Gear Reducers Manufactured to Your Exact Specifications

At Ondrives.US, we can assist with designs, modifications, prototypes, and complete production of custom drive components and gears for any application. If your project specifications require custom mechanical components, our engineering team can produce parts and components that match your drawings and meet your performance needs.

The Ondrives.US Advantage:

Ondrives.US has been designing, engineering, and manufacturing reliable, high-performance gearboxes and gear reducers for over three decades. Our BLN Series High-Ratio gear reducers use the second set of gears to accomplish higher reduction ratios not normally supplied in a bevel gearbox. These right-angle gear reducers are available in numerous frame sizes, reduction ratios, and torque levels to meet your unique application requirements.
  • High-efficiency heavy-duty bevel gear reducer (as high as 88% at 1,000 RPM)
  • High ratio gearbox options – 6:1, 12:1, 18:1, 24:1
