The hollow output shaft architecture, available with keyed bores or external shrink disc couplings, eliminates flexible couplings, laser alignment routines, and costly foundation beds.
Drive reaction torque is absorbed by an adjustable torque arm assembly with an elastomeric bushing that dampens mechanical shock during heavy motor starts.
Frame sizes F 10 to F 90, torque capacity to 14 000 Nm, direct shaft mounting with shrink disc, torque arm.
Bonfiglioli VF & W Series Worm Gear Units
Bonfiglioli VF series (sizes VF 27 to VF 250) and W series (sizes W 63 to W 110) worm gear units deliver compact, cost-effective, and exceptionally quiet mechanical reduction.
The worm shaft is machined from alloy steel, surface-hardened and precision ground, while the worm wheel rim is centrifugally forged from premium CuSn12Ni2 tin bronze alloy.
The VF and W series feature single-stage reduction ratios from 7:1 to 100:1, universal multi-surface cubic mounting enclosures, and natural mechanical self-locking characteristics under high gear ratios.
Bonfiglioli HDP & HDO Series Heavy-Duty Industrial Gearboxes
Bonfiglioli HDP (parallel shaft) and HDO (bevel-helical) heavy-duty industrial gearboxes are engineered for extreme operating regimes in mining, mineral processing, cement, metals, and pulp industries.
Heavy-section monobloc ductile iron housings safeguard internal gearing against frame deflection while transmitting output torque up to 210 000 Nm.
Units are equipped with forced pressure lubrication circuits, internal cooling coils or external air-oil heat exchangers, and grease-purged Taconite labyrinth seals to block severe abrasive dust ingress.

Engineering Selection of Industrial Gearboxes & Motors for Heavy Industry
Sizing industrial drives for heavy conveyors, mixers, crushers, and lifting machinery requires rigorous calculation of dynamic torque, shock load factors, thermal dissipation capacities, and radial shaft forces. SpareX application engineers review system duty cycles to select modular 300M series planetary gearboxes delivering high power density up to 1 280 000 Nm within constrained mechanical footprints. For continuous bulk handling, we calculate C series coaxial helical gearmotors or A series bevel-helical units from A 05 to A 90, providing quiet operation, superior thermal performance, and high gear mesh efficiency. Compact F series shaft-mounted gearboxes with hollow output shafts and shrink discs mount directly onto head pulley shafts, eliminating coupling alignment issues and external foundation beds. For extreme mining and mineral processing mills, we supply HDP parallel-shaft and HDO bevel-helical heavy units equipped with forced pressure lubrication, external oil-air coolers, and Taconite labyrinth seals to withstand highly abrasive dust and continuous shock vibrations.
To prevent unplanned operational downtime across processing facilities, SpareX supplies authentic Bonfiglioli replacement parts, wear components, and overhaul kits. Our program covers surface-hardened helical gear pairs, planetary sun gears, planet carriers with needle bearings, internal ring gears, solid and splined hollow shafts, and external shrink disc locking assemblies. We provide replacement worm and wheel sets for VF and W series machined from premium tin bronze alloys, Viton FKM and NBR reinforced oil seals, shimming kits, IEC motor adapter kits, and breather valves. For Bonfiglioli electric motors, we supply genuine FD and FA electromagnetic brake units, rectifier modules, replacement cooling fans, encoder kits, terminal blocks, and electronic power IGBT modules for AxiaVert, Agile, and Active frequency inverters.
