Wanshsin WVRBR replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original Wanshsin part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
What a spiral bevel gearbox is
A spiral bevel gearbox turns the drive through 90 degrees using bevel gears with curved, spiral teeth. Curved teeth engage gradually, giving smoother, quieter running and higher load capacity than straight bevels. In servo applications, a spiral bevel stage is often combined with a planetary stage to produce a right-angle precision gearbox. Efficiency is typically high, close to that of a planetary, which makes spiral bevel units preferable to worm gears where efficiency and back-drivability matter.
When engineers choose a spiral bevel gearbox
Choose a spiral bevel gearbox when the motor must sit at right angles to the output to save space, such as on gantries, conveyors and robot arms. It gives efficient, precise right-angle transmission. The trade-offs are cost and limited single-stage ratio compared with worm gears, which reach high ratios in one stage. For self-locking or very high ratios at low cost, a worm gear may suit better, but at lower efficiency.
How to specify the Wanshsin WVRBR
Send these with your enquiry and an engineer can confirm the right WVRBR variant:
- Ratio and output speed (:1, rpm)
- Output torque, nominal and peak (Nm)
- Backlash (arcmin)
- Input speed limit (rpm)
- Output shaft or hollow bore
- Motor interface
- Radial and axial load (N)
Common mistakes to avoid
- Assuming right-angle units match inline torque ratings
- Ignoring noise at high speed
- Not checking the mounting orientation for lubrication
- Overloading the output bearing with side loads

Wanshsin WVRBR: frequently asked questions
Can you help replace Wanshsin WVRBR or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Wanshsin WVRBR?
Right-angle WVRB for heavier duty, offered in larger frame sizes. Published series figures include rated torque 2,000 Nm, ratio 3:1, ratio 200:1. It is available through our supply network, and our engineers can confirm the right variant for your application.
Who makes the Wanshsin WVRBR?
The Wanshsin WVRBR is made by Wanshsin (WANSHSIN Seikou (Hunan) Co., Ltd.) available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.
What is the rated torque of the Wanshsin WVRBR?
The published series maximum rated torque is 2,000 Nm. Individual models and sizes in the WVRBR range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the Wanshsin WVRBR?
We can assess suitable replacement options. On published figures, APEX Dynamics AE / AER / AES / AESR and LeaderDrive LCD are options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
Spiral bevel or worm gearbox for a right-angle drive?
Spiral bevel gears are more efficient, run cooler and back-drive freely, which suits servo axes and dynamic motion. Worm gears offer high ratios in one stage and may resist back-driving, but efficiency falls at high ratios. Choose spiral bevel for servo performance, worm for simple low-cost holding.
Is a right-angle gearbox less precise than an inline one?
Not necessarily, but the added bevel stage typically adds a little backlash and reduces stiffness. Precision right-angle planetaries combine a spiral bevel input stage with a planetary output and publish backlash figures. Compare the right-angle unit's figures directly with the inline version.
