Technical specification
Supplied brand: Vidishi Auto — not Jiahuang-branded; the original maker is referenced for fitment cross-checks only.
Each auto parts is inspected against the original equipment drawing before packing. Tight tolerances keep the unit stable through thermal cycling. The electrical rating is validated across the temperature range. Dimensions are per the OE drawing. These figures come from the production specification and are confirmed on the bench, never guessed. Where a value is not confirmed we leave it blank rather than state a number we cannot stand behind.
The auto parts is supplied with the connector and sealing items shown in the gallery, so the installer has everything needed for a clean fit. Torque and clearance follow the original equipment spec.
The Color of fixed matters because it is part of the specification we confirm before dispatch.
Every unit passes a pre-dispatch check before it is packed: response at the rated condition, a pressure or flow confirmation where the specification requires it, and a visual inspection of the seal and connector. A unit either passes and gets stamped or it is pulled from the batch. Shipping untested stock saves nothing when the unit comes back.

Fitment
Fitment verification
Confirm the engine code plate and the part number jiahuang-b57890 before purchase. This auto parts fits the applications in our fitment list. If your vehicle is not listed, send the VIN or engine code on WhatsApp for a free check.
Lay the new unit next to the old one before fitting — the casting marks, the connector keyway, and the mounting holes have to line up. A near-miss revision will fight the seat and can take the surrounding circuit with it.
| Part number | jiahuang-b57890 |
|---|---|
| Verification channel | Send the VIN or a photo of the old part on WhatsApp — written confirmation before you pay. |
Typical replacement scenarios
Direct replacement
The old auto parts has failed and the vehicle is down. Match jiahuang-b57890 to the old stamping and fit the same reference — the fastest path back to service.
Preventive swap
During an adjacent repair, replace the auto parts while the access is already open. Cheaper than a second teardown later.
Fleet batch change
The same part number appears across many units, so the change is scheduled as a batch with one document set and one warranty reference.
In every scenario the first step is identical — confirm jiahuang-b57890 against the old stamping before the wrench moves.
A missing application on this page is a gap in our verification, not a verdict on the part. Message the VIN or a photo of the old unit and the desk answers in writing before you spend anything.

Symptoms & engineering notes
Engineering notes
The R/S/F/K Series Industrial Helical Gearbox Motors Parallel Shaft Helical-Worm Gearmotors is designed around the original equipment geometry so the auto parts seats without modification. Tight tolerances keep the unit stable under thermal cycling. Actuation stays consistent across the rated temperature range. The pressure path is validated on the test bench. Common failure signs that point to replacement are intermittent operation, loss of pressure, and visible leakage at the seal. Replace on a clean bench and torque to the OE spec. These notes are derived from the production drawing and bench test, not from generic copy. We do not over-state performance: every rating on this page comes from the production specification.
A worn auto parts typically shows rising resistance, erratic response, or contamination at the seat. Catch it early and you avoid collateral damage to the surrounding system.
Typical signs the auto parts is finished: intermittent function that clears after a tap, a reading that wanders as the temperature changes, or heat marks around the seat pointing to a poor connection. Swap it at the first sign and the downstream parts stay protected; a five-minute check after fitting keeps the comeback away.
Our rule is simple: publish what the bench proved, leave the rest blank. Inflated ratings sell once; honest ones keep the reorder coming.
Leave the new auto parts sealed until the bench is ready. Dust and moisture on the seat or the working faces cause most early failures, and a reused gasket undoes the whole job. Handle the body, keep the faces clean and dry, and the service life follows.
Verified details from supplier and reference listings: The R series is a coaxial inline helical gearmotor, the F series uses a parallel shaft layout and the K series gives a right-angle helical bevel output.. The S series combines a helical input stage with a worm output stage, providing a compact 90-degree transmission with high ratios and possible self-locking.. Helical gearmotors in these families typically reach 94 to 98 percent transmission efficiency, while worm stages run at lower efficiency.. Gears are made from 20CrMnTi alloy steel with carburizing, quenching and grinding, in HT250 cast iron housings for durability and heat dissipation.. Typical applications include conveyors, mixers, agitators, packaging machines and material handling across food, mining and automation industries.. This Jiahuang unit runs at 1400 rpm input with 14 to 186.7 rpm output and 1.8 to 2430 Nm torque, with OEM customization and a 1-year warranty..

Installation
- Disconnect power and relieve system pressure.
- Remove the old auto parts after noting the part number jiahuang-b57890.
- Clean the seat and check for debris or worn seals.
- Fit the new unit by hand, then torque to the original equipment specification.
- Restore power, pressurise slowly, and inspect for leaks.
- Run a functional test before returning the vehicle to service.
Installation difficulty is moderate. If unsure, use a qualified technician. Keep the old part until you confirm the new unit behaves correctly.
Set up before you start: torque wrench, clean bench, and the old unit beside the new one. Most comebacks trace back to a dirty seat or a guessed torque value. If the old part shows heat damage or contamination, find that root cause first — a new auto parts in the same conditions fails the same way.

Transmission & gearbox details
For transmission and gearbox products, confirm the reduction ratio, the input and output speed, and the torque rating against the drawing before fitting. Confirm the rating on the label. The cast housing keeps alignment under load. A worn gear set shows up as noise, backlash, or heat long before it fails outright.
- Confirm the reduction ratio and direction of rotation.
- Match the input flange and shaft diameter.
- Verify the output torque rating covers the driven load.
- Check the mounting face and bolt pattern.
Ratio and torque are the two numbers that decide whether a gearbox suits the machine. A unit specified for continuous duty will run cooler and quieter than one sized at the limit, and the service factor on the nameplate tells you which one you are buying. When you read a datasheet, the input speed, output speed, and rated torque are what the engineer actually checks.

Revision history for the drawing is available to auditors.

Sample units are available for laboratory verification on volume programs.
Lubrication & sealing
Use the oil grade and fill volume marked on the unit. Running a gearbox low on oil is the fastest way to destroy the bearings and the tooth flanks. Check the seals at every service; a weeping seal lets dust in and oil out. Replace the breather if it is blocked, or pressure will push oil past the seals.
Oil does three jobs in a gearbox: it separates the teeth, it carries heat away, and it flushes wear particles to the filter or the sump. Viscosity is chosen for the ambient range on the nameplate, not for the average day, and synthetic grades hold their film strength longer under cold starts. Magnetic drain plugs are cheap insurance for iron wear debris.

Fitment & assembly checks
Set the unit on a clean face and check the coupling alignment with a dial indicator before final torque. Torque the mounting bolts in sequence to the specification for this auto parts. A soft foot or a misaligned coupling will destroy the input bearing within months.
After assembly, rotate the input by hand and feel for tight spots or roughness. Run a short no-load break-in, then check the case temperature and listen for noise at each bearing position. Document the alignment readings so the next swap follows the same record.
