Gear Boxes And Speed Reducers
Worm gear right angle reducers come in standard modular configurations. Most manufacturers mirror the others specifications. Worm gear reducers accommodate a wide range of ratios from 5:1 through 3600:1 and horsepower ranges of .012 through 100. HP and ratios depend on the reduction of the box. John Bridge can build many of the standard boxes in house. Give us a call were ready when you are.
Helical Parallel Shafts:
Helical parallel shaft and bevel helical right angle gear drives tackle the most demanding applications. Case hardened and ground helical gears; horizontal split case for ease of maintenance and large diameter output shafts to maximize overhung loads. With maximum torque to 1150500 lb in and ratios from 6.3:1 to 315:1. When it comes to your most demanding applications John Bridge Sons has the expertise and product to satisfy your needs.
FALK QUADRIVE® SHAFT MOUNTED DRIVES - NEW 5000 SERIES
With the Falk Quadrive, you don't have to turn a blind eye to drive removal issues.

It's a simple fact. The heavy duty, shaft-mounted Falk Quadrive features a completely unique design that makes it the easiest, quickest shaft-mounted drive to install and remove.
Quadrive is built to stand up to continuous rough duty. And now, with new higher ratings, you may be able to downsize the drive, saving money right up front.
The Falk TA Taper Bushing® design makes sure that drive removal is not only simple, but won't damage the drive, or driven equipment. You don't need extra time. You don't need extra tools. And you're assured safe, worry-free operation.
In a game where there are so few sure things, Falk Quadrive is the right shot to take.
The torque-assist taper bushing makes installation and removal easy. It eliminates binding found with twin-taper and single-flanged bushings. Concentric operation minimizes wobble, even on worn shafts. The quill cover keeps contaminants out and protects the outboard shaft seal. The inboard bushing location minimizes sheave overhang, saving high-speed bearings. Minimal shaft engagement is required for retrofits.
Lifetime Removal Guarantee
Due to the unique properties of the TA Taper® Bushing, Quadrive is guaranteed to come off the shaft regardless of length of service or operating conditions, or we'll replace it FREE. That's a promise no other shaft-mounted drive can make.
