Right Angle Gearboxes

Frequently Asked Questions

Bevel vs worm right-angle gearbox — which should I specify?

Broadly, bevel and helical-bevel right-angle units favour efficiency (often 90-98% per stage) and stiffness, suiting continuous-duty and higher-power drives; worm right-angle units are more compact at high ratios and can be self-locking, but typically at lower efficiency and with more heat to dissipate. The choice usually turns on ratio, duty cycle, efficiency targets and footprint. Share your load and ratio and we can help frame the trade-off with a partner.

What's the typical MOQ for right-angle gearboxes?

It depends on frame size and ratio. Larger industrial right-angle units can start as low as 5-15 pieces per size/ratio, whereas small standard frames typically carry MOQs in the 25-100 piece range. Mixed-size orders consolidated under one spec package usually accept smaller quantities per line. Treat figures as indicative until a partner is matched to your drawing.

Which certifications and test reports can be provided?

Where specified, partner manufacturers can supply units under ISO 9001 with gear-rating to AGMA / ISO 6336, plus load, running and efficiency test reports and material traceability. CE marking under the Machinery Directive can be coordinated for EU shipments, and ATEX/IECEx execution arranged for hazardous-area duty. The exact documentation set is confirmed against your specification at inquiry stage.

What ratios, mountings and lubrication options are available?

Bevel stages run roughly 1:1 to 6:1, with helical-bevel and worm builds reaching higher reductions. Output is offered as solid or hollow shaft, with foot, flange (B5/B14) or shaft-mounted arrangements and IEC/NEMA motor adapters or free input shafts, in multiple mounting positions. Lubrication is mineral or synthetic PAO (ISO VG 220/320), often lifetime-filled on smaller frames. Service factor is selected per AGMA guidance for your load class.

Can you support OEM approvals and customisation?

A subset of Himalay's partner network supplies right-angle drives to OEMs in material handling, cement, sugar and marine sectors, and can build to customer drawings including special ratios, shaft configurations and low-backlash classes. Share your spec or drawing at inquiry stage and we match a qualified partner; supplier audits can be arranged on a development track where required.

What lead time should I plan for?

Catalogue and lightly configured right-angle units typically take around 4-8 weeks to manufacture, test and pack; engineered or large-frame units commonly run 10-16 weeks. Full CIF to Rotterdam, Antwerp, Jebel Ali or Dammam is generally 8-12 weeks door-to-door for standard product and 14-20 weeks for engineered specials, subject to confirmation.
