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. The cast iron body resists wear under continuous duty and holds tolerance through thermal cycling. The electrical rating is validated across the temperature range. Dimensions are 400*340*185cm. 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.
Packing includes the mating connector and the sealing items pictured in the gallery; nothing extra needs to be sourced before the install. Torque values and clearances follow the original equipment spec.
The Weight of 84kg matters because it matters for shipping and for hand-fitting in tight bays.
The Material of Cast iron matters because it decides wear life and resistance to the medium.
Before the unit ships we run a function check against the rated specification: actuation or response at the rated condition, a pressure or flow confirmation where the spec calls for it, and a visual check of the seal and connector. The result is either a pass stamped on the carton or the unit is pulled. We do not ship a unit we have not put through this check, because a comeback costs more than the test.

Fitment
Fitment verification
Confirm the engine code plate and the part number nmrv150-393d8e 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.

Typical replacement scenarios
Direct replacement
The old auto parts has failed and the vehicle is down. Match nmrv150-393d8e 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 nmrv150-393d8e 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 NMRV150 Flange Mounted RV Series Worm Gear Motor Speed Reducer Cast Iron Transmission Gearbox is designed around the original equipment geometry so the auto parts seats without modification. The cast iron element keeps tolerance under thermal cycling and vibration. 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.
Replace the auto parts when you see any of these: the function works only after a tap; the reading drifts with temperature; or the surrounding housing shows heat discolouration from a poor seat. Catching it early protects the more expensive parts downstream. After fitting, a five-minute functional test saves a comeback.
We do not claim performance we cannot confirm. Where a value is not set by the production line we leave it blank rather than copy a competitor number. That discipline is what keeps this page trustworthy for professional buyers.
Store the new auto parts in its sealed bag until fitment; dust and shop moisture on the seat or contacts are the avoidable causes of early failure. Handle by the body, not the working surfaces, and never reuse the old gasket on a new unit. A clean, dry fit is most of the battle for a long service life.
Verified details from supplier and reference listings: NMRV150 designates a 150 mm center distance worm gear reducer, the largest standard size in the RV series.. Standard ratios run from 7.5:1 to 100:1, and ratios of 30:1 or higher usually provide self-locking against load reversal.. Cast iron housings with centrifugally cast bronze worm wheels suit higher torque duties, while smaller RV sizes use aluminium alloy housings.. B5 or B14 input flanges allow direct mounting of IEC standard motors from 0.06 kW up to 15 kW.. Rated output torque for the NMRV150 spans roughly 1.8 to 2430 N.m depending on ratio and motor power.. Typical applications include conveyor lines, packaging machinery, mixers, agitators and lifting platforms..

Installation
- Disconnect power and relieve system pressure.
- Remove the old auto parts after noting the part number nmrv150-393d8e.
- 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.
Most shops rate this job as routine. If your toolkit is short or the access is tight, a technician is the cheaper option; keep the old part on the shelf until the replacement has run clean.
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 iron 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.

Specification changes are notified to standing customers before shipment.
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.
Distributors book stock against valve gear because the batch record travels with the carton.
Rebuilders keep records for valve gear with the specification sheet packed on top.
Workshops hold shelf space for valve gear so the fitter works to torque values rather than habit.
Reliability data for this Auto Parts on the applications in the fitment table comes from field returns, not from a brochure table.
