    • Parallel Shaft Gearboxes

    Helical gearboxes with parallel shafts for conveyors, mixers, and industrial duty applications.

    Parallel-shaft gearboxes are helical gear drives in which the output shaft runs parallel to, but offset from, the input shaft. Torque is transmitted through one or more helical gear stages whose shaft centres lie side by side, so the drive keeps the high efficiency and smooth, quiet meshing of helical gearing while presenting the output low and to the side. That offset geometry suits the unit to side-mounting against a machine frame and to hollow-shaft fitting directly onto a driven shaft, which is why parallel-shaft units dominate conveyor, agitator, extruder and bulk-handling drives.

    The family is defined by stage count and mounting rather than by a change of tooth principle. Two- and three-stage trains are common, covering wide ratios, with single-stage reductions near 1.25:1 to 8:1 building to roughly 200:1 and higher across stages. Because every stage is helical, per-stage efficiency is generally high, commonly cited near 96-98 percent, leaving multi-stage units well above 90 percent overall. Load rating follows AGMA 2001/2101 or ISO 6336, with enclosed-drive practice per AGMA 6010 and gear quality to ISO 1328 / AGMA 2015. Foot-mounted, flange-mounted and shaft-mounted (hollow-shaft with torque arm) versions cover most layouts.

    Construction uses case-hardened alloy-steel gears, typically 20MnCr5 or 18CrNiMo7-6, with ground or lapped profiles, in cast-iron housings (aluminium on the smallest frames). Bearings are SKF/FAG-equivalent, with shaft seals, drain/breather provision and ISO VG 220/320 mineral or synthetic PAO lubrication.

    Hollow output shafts accept keyed bores or keyless shrink-disc fittings; solid shafts and output flanges are alternatives. Inputs take IEC/NEMA motor adapters, servo flanges or free input shafts, and the housing's lateral mounting faces allow several mounting positions. Service factor is selected per AGMA SF.

    Himalay's MSME partners manufacture parallel-shaft helical gearboxes and gearmotors with gear-rating to AGMA/ISO 6336, ISO 9001 quality systems, load/efficiency test reports and traceability; CE (Machinery Directive), ATEX/IECEx for hazardous areas, and SABER (Saudi Arabia) coordinated as part of the standard order flow.

    Frequently Asked Questions

    When is a parallel-shaft gearbox the right choice over an inline or right-angle unit?
    Choose parallel-shaft when you want the high efficiency of helical gearing (commonly ~96-98 percent per stage) plus an offset output that side-mounts against the machine and fits directly onto a driven shaft via a hollow bore. Inline (coaxial) units are more compact axially but put the output on the same line; right-angle bevel-helical units suit a 90-degree layout. For conveyors, agitators and shaft-mounted drives, parallel-shaft is usually the most practical fit.
    What's the MOQ for parallel-shaft gearboxes?
    It depends on frame size and ratio. Large engineered parallel-shaft units: MOQ can start at 1-5 pieces per size. Smaller standard frames and gearmotors to catalogue: typical MOQ starts around 20-50 pieces depending on manufacturer and configuration. Mixed-size orders under one spec package generally accept smaller quantities per line.
    Which certifications and compliance options are available?
    Where specified, partner manufacturers supply CE marking under the Machinery Directive, ATEX/IECEx for hazardous-area duty, and ISO 9001 quality systems. Gear-rating documentation to AGMA 2101 / ISO 6336, load and efficiency test reports, and material traceability can be provided. IP55/IP65 ingress and specific finishes are available where the application requires them.
    What ratios, mountings and output options can be configured?
    Two- and three-stage trains cover wide ratios, from about 1.25:1 to 8:1 single-stage up to roughly 200:1 and beyond combined. Hollow output shafts take keyed bores or keyless shrink-disc fittings; solid shafts and flanges are alternatives. Inputs accept IEC/NEMA adapters, servo flanges or free input shafts, with foot, flange and shaft-mounted (torque-arm) positions. Lubrication is ISO VG 220/320 and service factor is selected per AGMA SF.
    Do your partners supply to OEMs and to end-client specifications?
    A subset of Himalay's partner network supplies to OEMs in material handling, cement, sugar and bulk-handling, building to their drawings and approved-vendor requirements. Share your spec or drawing at inquiry stage and we match a qualified partner; supplier audits can be arranged on a development track where an end client requires them.
    How long does a parallel-shaft gearbox order take?
    Catalogue gearmotors and standard frames: typically 6-10 weeks manufacture, test and packaging. Larger engineered units: 12-16 weeks. Full CIF to Rotterdam, Antwerp, Jebel Ali or Dammam is typically 8-12 weeks door-to-door for standard product, and 14-20 weeks for engineered or large units.
