Gear Reducers

Precision Planetary Reducer Gearbox
The Saineer P Series Planetary Gear Reducer is built on proprietary core technology, specifically engineered for servo automation and precision machinery. Featuring a modular design and fully independent intellectual property rights, this precision planetary reducer delivers ultra-high torque density and exceptionally low backlash. It is perfectly tailored for various high-torque industrial applications, empowering the upgrade of high-end equipment with its outstanding performance.

Custom Non-standard Locomotive Transfer Case
We support one-stop customized services including personalized transmission ratio calibration, shaft end structure improvement, overload protection configuration and appearance dimension optimization.

Industrial Modular Helical Gear Reducer
Saineer independent-developed four-type modular helical gear reducers are mature general industrial transmission units built on self-optimized modular structure design. We classify the product lineup into 4 structural categories by transmission layout: Inline coaxial helical (R Type), parallel-shaft helical (F Type), helical-bevel right-angle (K Type), and helical-worm composite (S Type).

All housings, gear structures, sealing systems and mounting dimensions are independently optimized by Saineer R&D team, with exclusive mold and structural improvement, not copied from any third-party brand design. These gear units cover power range 0.12kW–200kW, wide reduction ratio options, multiple mounting ways, widely matched with AC motors, servo motors and customized power sources for global industrial equipment.

Saineer self-developed SWL ball screw jack and JWM trapezoidal worm screw lifter are industrial linear lifting units with self-locking function. Alloy bronze worm wheel & hardened worm gear deliver heavy load capacity, support manual & electric driving, single or multi-jack synchronous lifting. Two screw types match high-speed frequent operation and static heavy positioning respectively, independent proprietary design without imitation for all industrial adjustment and lifting machinery.

Aluminum Right Angle Worm Gear Reducer
Saineer NMRV / NRV / RV series worm gear reducers are compact right-angle industrial transmission units with self-locking performance. Adopting high-precision cylindrical worm and tin-bronze worm wheel meshing structure, this series realizes 90° vertical power transmission with small volume, large reduction ratio, stable operation and outstanding safety performance.

Saineer Spiral Bevel Steering Gearbox
Saineer T Series spiral bevel steering gear units are independently developed 90° right-angle power commutating transmission devices, adopting one-stage spiral bevel gear meshing structure to realize vertical power conversion between intersecting shafts.
All cast iron housing molds, spiral bevel tooth profiles, bearing matching and sealing systems are fully self-optimized by Saineer R&D team without copying external brand appearance or internal structure. This series covers multiple frame sizes T2/T4/T6/T7/T8/T10/T12/T16/T20/T25, with standard ratios 1:1, 1.5:1, 2:1, 2.5:1, 3:1, 4:1, 5:1, supporting bidirectional positive & reverse rotation, widely matched with various industrial transmission equipment.

Heavy Duty Planetary Cycloidal Gear Reducer
Saineer X/B Series Cycloidal Pinwheel Reducers are self-developed high-torque low-speed industrial reduction equipment based on planetary cycloidal transmission principle. Different from traditional helical gear reducers, this series adopts cycloidal wheel and pin gear meshing structure, featuring ultra-large reduction ratio, strong shock resistance, heavy load capacity and outstanding durability.

Saineer HB Series Heavy Duty Industrial Gearbox
The Saineer HB series industrial gear unit features a modular universal housing design. A single cast iron housing supports both parallel shaft and 90° orthogonal transmission, accommodating horizontal foot-mounted, vertical flange-mounted, torsion arm, and swing base installations. This design results in fewer spare part types and strong interchangeability of accessories, which greatly reduces inventory costs for clients utilizing the Saineer HB series industrial gear unit. Furthermore, all gears within the Saineer HB series industrial gear unit adopt alloy steel carburizing quenching combined with precision profile grinding, reaching DIN6 high precision grade. The gears offer large meshing overlap, strong overload and shock resistance, and stable operation, with running noise controlled below 72dB.
