Our Standard Products

The most commonly used classifications for China standard cycloidal reducers are the B/X series.

According to the mounting style, it can be categorized as Horizontal (Foot-Mounted), Vertical (Flange-Mounted), Double-Stage (High Ratio).

According to the input option, it can be categorized as Direct Motor Coupled, Solid Input Shaft, IEC Flange Adapter.

BL shaft input type

Built for flexibility. The independent shaft input allows you to use non-standard, explosion-proof, or specific brand motors via belt or coupling connections.

BLD motor input

Standard for chemical agitation. Its compact, vertical flange design connects directly to the motor, saving space and eliminating transmission loss.

BLED two-stage

Engineered for high viscosity. The double-stage internal structure achieves ratios over 1:100, delivering massive torque for heavy-duty mixing tanks.

BW shaft input type

Durability meets maintenance. The motor-separated design makes it easy to replace motors in harsh environments without disassembling the entire gearbox.

BWD motor input

Our best-selling all-rounder. Plug-and-play foot installation makes it perfect for 90% of logistics, packaging, and general machinery needs.

BWED two-stage

Replace bulky traditional gearboxes. This unit handles extreme shock loads and low speeds with ease, ideal for crushers and heavy feeding equipment.

💡 Technical Note: Custom Combinations

The double-stage ratios listed above represent typical standard configurations. However, due to the modular design of our cycloidal reducers, any combination of the single-stage ratios (Level 1) can be paired to create a customized double-stage unit.

Formula: Ratio A (Stage 1) × Ratio B (Stage 2) = Total Reduction Ratio
Example: 87 × 43 = 3741:1

If you require a specific ratio not listed above, please contact our engineering team for a custom configuration.
