Bevel Gearboxes

Frequently Asked Questions

When should I choose a bevel gearbox over a worm or helical right-angle drive?

As a rough guide, bevel gearboxes suit applications that mainly need a compact 90 degree direction change with high efficiency (often 90-98% per stage) and modest reduction up to roughly 6:1 single-stage. Worm drives can be more compact at high ratios and offer self-locking, but typically at lower efficiency; helical-bevel combinations are usually preferred where both a large reduction and right-angle layout are needed. The trade-off is generally efficiency and stiffness versus ratio and cost — share your duty cycle and we can help frame it with a partner.

What's the typical MOQ for bevel gearboxes?

It depends heavily on frame size and ratio. For larger industrial bevel units, MOQs can start as low as 5-15 pieces per size/ratio; for small standard frames and catalogue miter boxes, typical MOQ tends to land in the 25-100 piece range. Mixed-size orders consolidated under one spec package usually accept smaller quantities per line. Treat these as indicative until a specific partner is matched to your drawing.

Which certifications and test reports can be provided?

Where specified, partner manufacturers can supply units under ISO 9001 quality systems with gear-rating documentation to AGMA / ISO 6336, plus load, no-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. Scope is confirmed against your specification at inquiry stage.

What ratios, mountings and lubrication options are available?

Single-stage bevel ratios generally run 1:1 to about 6:1, with multi-stage helical-bevel 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. Lubrication is typically 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 bevel drives to OEMs in material handling, cement, sugar, marine and similar sectors, and can build to customer drawings including special ratios, shaft ends 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 bevel 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.
