Purchase now: Bonfiglioli A 30 2 UH 15 P100 B5 Gearbox
Purchase now: Atlantechdrives provides you the A 30 2 UH 15 P100 B5, a premium, high-efficiency orthogonal (right-angle) helical-bevel gear reducer masterfully engineered by the heavy-duty power transmission experts at Bonfiglioli. Belonging to the elite A Series, this robust industrial gearbox is specifically designed to provide the space-saving benefits of a 90-degree drive while delivering the extreme mechanical efficiency (often exceeding 95%) of a helical gear train. This specific unit features a heavy-duty frame size (Size 30) and utilizes a 2-stage reduction design to achieve a highly dynamic, fast 15:1 reduction ratio. Its standout physical feature is the «UH» (Universal Hollow) output configuration featuring a standard keyway, which allows the entire heavy gearbox to slide directly onto your driven machine’s solid shaft, eliminating the need for complex couplings. Furthermore, it is designed to accept a massive, high-horsepower IEC P100 electric motor via a large B5 mounting flange. It is the absolute ultimate transmission choice for high-speed material extruders, dynamic rotary tables, and severe-duty conveyor systems where energy conservation and raw power are strictly required.
Technical Specifications of the A 30 2 UH 15 P100 B5
The A 30 series utilizes a highly rigid unibody cast-iron housing that maintains absolute internal bevel gear alignment even under continuous, brutal radial and axial shock loads. The internal helical and bevel gears are case-hardened and precision-profiled for virtually silent, continuous 24/7 high-velocity operation.

Expert Installation Advice: Torque Arm Anchoring and Dynamic Reversibility
Because the A 30 is a heavy, shaft-mounted gearbox (suspended directly on the driven machine shaft via the hollow bore), the entire cast-iron housing will violently attempt to spin around the shaft when the massive P100 electric motor engages. Expert Tip: You must safely anchor the gearbox to the machine frame using a heavy-duty torque arm (reaction arm). Never bolt the torque arm completely rigid; you must use rubber vibration-dampening bushings at the anchor point. If bolted rigidly, shaft runout will destroy the internal bearings. Additionally, automation engineers must profoundly understand that a highly efficient 15:1 helical-bevel gearbox is completely dynamically reversible. Unlike a worm gear, it offers absolutely zero resistance to back-driving. If your application involves holding a suspended load against gravity or requires instant, precise positional stops, you must install an external failsafe electromechanical brake on your heavy AC motor.
Maintenance: Hollow Shaft Anti-Seize Protocols
One of the most catastrophic and costly maintenance nightmares in industrial automation involves heavy hollow shaft gearboxes getting permanently stuck to the machine shaft due to «fretting corrosion»—microscopic vibrations that cause the steel surfaces to rust and cold-weld together. Before sliding the massive A 30 gearbox onto your machine shaft, you must thoroughly clean the shaft and apply a heavy coating of high-quality anti-seize paste (such as Molybdenum Disulfide) inside the hollow bore and heavily along the keyway. This simple preventative step guarantees the heavy gearbox can be easily removed for maintenance years down the line without the need for destructive cutting torches or massive hydraulic presses.
Frequently Asked Questions (FAQs)
Q: Why choose the A 30 Helical-Bevel instead of a similarly sized cast-iron worm gear for a 15:1 ratio?
A: Pushing the high horsepower of a P100 motor through a worm gear generates massive sliding friction, converting valuable electrical energy into wasted heat. The A 30 transfers this massive torque through the rolling contact of precision-ground gears, meaning it consumes significantly less electrical amperage, runs drastically cooler, and provides a much longer operational lifespan without bronze gear wear.
Q: What size motor shaft does the P100 B5 input accept?
A: A standard IEC 100 frame motor features a thick 28mm diameter solid shaft. The B5 mounting flange for the 100 frame has a large outer diameter of 250mm. The gearbox input quill and mounting face are perfectly matched to these standard heavy-duty IEC dimensions.
