Jershtech DC Motors
Engineered with low-temperature synthetic lubricants, hardened steel gear trains, and high dynamic efficiency to support Erdenet's severe ambient demands.
Understanding the environmental, operational, and engineering requirements of Orkhon Province's industrial infrastructure.
Erdenet stands as one of Asia's primary copper and molybdenum extraction hubs. Continuous slurry monitoring, automated chemical reagent dosing, sample transportation, and crushed-ore conveyor belt sampling rely on sub-fractional micro gear motors capable of unyielding 24/7 continuous operation.
Mongolia’s extreme sub-arctic winter temperatures cause standard lubricants to freeze and gear alloys to undergo brittle fracture. Our 37mm gear motors supplied to Erdenet feature aerospace-grade synthetic polyalphaolefin (PAO) greases and thermal expansion-compensated gear meshing gaps.
Fine silica, pulverized ore dust, and intense industrial machinery shockloads degrade standard off-the-shelf electric motors. We implement IP65-sealed gear housings, oil-impregnated sintered bronze bushings, and precision ball bearing shaft supports for heavy radial stress survival.
An authoritative analysis of gearbox kinematics, metallurgy, electrical matching, and structural durability for modern B2B procurement teams.
The 37mm gearbox architecture (commonly designated as GB37 or 37GB) relies on multi-stage reduction to transform high-speed motor rotation into controllable high-torque performance. In extreme industrial environments such as Erdenet, gear tooth shear strength is paramount.
While commercial grade motors utilize powdered metallurgy gears that can fracture under sudden reverse load or shock, our industrial 37mm gear motors incorporate precision CNC-hobbed carbon steel gears (20CrMnTi) and hobbed brass primary pinions. This yields a torsional load threshold up to 250% higher than standard micro gear motors.
"Selecting the optimal gearbox ratio requires balancing output velocity, radial load tolerances, and thermal dissipation thresholds. Our 37mm platform bridges micro-scale footprints with heavy-duty output."

Shenzhen Jershtech Technology Co., Ltd. is a forward-thinking China DC motor factory bridging the gap between advanced manufacturing efficiency and global engineering standards. We design and build high-efficiency DC and BLDC motors that power modern robotics, automotive systems, medical devices, and smart automation worldwide.
We operate with a simple philosophy: Engineered to last, built to fit. By integrating cutting-edge manufacturing tech with reliable quality control, we provide global B2B clients with the transparency of a local partner and the cost advantages of a top-tier Chinese manufacturer.
How our customized 37mm DC gear motors power crucial systems across mining, telemetry, and civic infrastructure.
Ore processing plants require extremely consistent, micro-metered delivery of flotation reagents. Our 37mm 24V DC high-torque low RPM motors (equipped with precision magnetic encoders) drive peristaltic pumps under continuous operation, maintaining steady volumetric flow despite fluctuating fluid viscosity caused by ambient winter temperatures.
Heavy machinery maintenance facilities and mining processing sheds in Erdenet demand automated airflow control to preserve ambient temperatures. Our customized 37mm 12V 150RPM motors provide high self-locking holding torque when paired with worm gear secondary stages, holding air dampers secure against fierce Mongolian steppe wind gusts.
Automated sampling arms regularly extract ore samples from moving conveyor lines. These actuators require rapid acceleration, precise stopping, and immense breakdown torque. Shenzhen Jershtech’s GB37-550 units handle the severe axial impact and vibration without gear teeth shearing.
The rail transport routes linking Erdenet with Ulaanbaatar and international trade corridors utilize motorized switches and signals. Our cold-rated micro planetary gear motors ensure consistent mechanical switching even when ice accumulation builds up inside protective switch boxes.
Streamlined procurement, fast transit options, and full technical OEM support directly from our Shenzhen production lines to Erdenet.
We provide streamlined multimodal freight solutions: direct rail transport via Tianjin Port through Zamiin-Uud into Ulaanbaatar and Erdenet industrial sidings, or expedited air freight to Chinggis Khaan International Airport for urgent maintenance batches.
Every motor shipment undergoes 100% automated electrical testing, noise chamber verification, gear backlash calibration, and salt-spray corrosion inspection before packing. Full ISO compliance documentation and CE/RoHS certificates are supplied with all shipments.
Need custom shaft lengths, specific gear ratios, integrated optical encoders, or specialized low-temperature wire leads? Our dedicated R&D engineering team delivers custom prototypes within 7 to 10 business days for technical evaluation.

In-depth technical answers for engineers, plant automation directors, and procurement officers sourcing 37mm gear motors for Erdenet and Northern Mongolia.
The 37mm gearbox housing (GB37 series) offers an optimal mechanical equilibrium between compact volumetric size and high structural torque carrying capacity. It accommodates heavy 500-series armatures (such as 550 and 555 brushed motors) while maintaining a small standard mounting pattern, making it ideal for space-constrained industrial enclosures.
Standard gear motors fail in severe cold due to lubricant solidifying and thermal contraction binding. For Mongolian regional orders, we utilize custom low-viscosity synthetic hydrocarbon lubricants rated down to -45°C, install specialized rubber shaft seals, and adjust internal gear tooth backlash tolerances to accommodate thermal contraction without dynamic drag.
37mm Spur Gearboxes feature offset output shafts, lower manufacturing cost, and higher high-speed efficiency, ideal for general dosing pumps and dampers. 36mm/37mm Planetary Gearboxes feature inline concentric shafts, distribute torque across multiple planet gears, and withstand far higher impact shock loads (up to 75 Kg.cm), making them suitable for severe robotic actuators.
Yes. We provide dual-channel magnetic Hall-effect encoders or high-resolution optical encoders integrated on the rear shaft of 550 and 555 armatures. This allows precise closed-loop speed feedback, position indexing, and rotation counting required for automated process metering.
We manufacture customized output shafts based on customer technical CAD drawings. Options include single D-cuts, dual flat surfaces, keyways, cross-drilled pin holes, external metric threads, and direct-machined lead screws (M3/M4/M6) for linear motion conversion.
Standard sample orders ship via DHL/FedEx/UPS air express within 5 to 7 days. Bulk production shipments (1,000+ units) typically ship within 15 to 20 days and are dispatched via cross-border rail/truck freight through Zamiin-Uud customs, arriving in Erdenet within 12 to 18 transit days.
