Importers and tool brands keep asking for the same three things in a cordless wrench: a headline torque number the market understands, a battery platform that survives warranty statistics, and a supplier who can hold color, logo and packaging consistent across reorder cycles. The JP-BS50X was developed around that brief. Its 500 N·m rating sits at the top of the consumer-visible range, the brushless drivetrain removes the most common failure point of brushed tools, and the 1:7 double-bearing mechanism has already run through series production for the JP line.
Customization goes beyond a sticker. Housing tooling accepts your color scheme; the battery shell, case, manual and box graphics follow your brand system; and the 20V pack interface is shared across the JP-BS family, letting you grow a program — 350 N·m, 500 N·m and beyond — on one battery standard instead of fragmenting your catalogue.
Nantong Shengqiang manufactures the complete kit in-house: wrench, both 2000mAh 10C packs, charger and carry case. That vertical scope means your quotation, your quality checks and your corrective actions all land on one desk rather than being scattered across trading intermediaries. Whether you are launching a brand, filling a catalogue gap or replacing an unreliable source, the BS50X ships as a finished, retail-ready program.
A top-of-range number your listing can lead with — verifiable at the anvil, not just on the box.
Eliminating brushes removes the dominant wear-out failure of cordless tools, which is exactly what your warranty reserve cares about.
One pack standard spans the JP-BS torque classes, so partners can build a line rather than a single SKU.
Wrench, two batteries, charger and case arrive as one production lot — no last-mile assembly from mixed vendors.
Housing, battery shell and case carry your logo; manuals and cartons print to your artwork and market language.
Twin bearings keep the hammer blows concentric through the production run, protecting both feel and return rates.
At 1.105 kg bare, the tool photographs and handles like a premium compact — a genuine shelf differentiator.
Trigger-mapped output from creep to 2700 r/min gives end users the control feel they read about in reviews.
Assembly, batteries and packaging come from our own production scope — one contact, one accountability chain.
Color, logo placement and kit contents are locked into the production file, so reorder cycles match your first approval.
Start with the 500 N·m flagship, extend to the 350 N·m class on the same battery standard as your range matures.
Pack configuration, plug type and case style adjust to your market's expectations — agreed in writing before production.
Housing color, logo pad-print or laser marking, battery shell branding, case design, manual language and master-carton artwork are all within the standard OEM scope. Specific combinations are confirmed in the project file before tooling and production.
Order quantities, unit pricing and production schedules are set per contract and depend on configuration and season. Contact us with your target volumes and we will return a written production plan for the exact kit you specify.
Certification requirements differ by destination market and configuration; the applicable items are agreed as part of the contract documentation for each order rather than claimed generically here.
Yes — the JP-BS family shares the 20V pack platform, so combined orders across the 350 N·m and 500 N·m models are a common way for partners to open a range with a single shipment.
Warranty structure, spare-part ratios and technical support for your market are negotiated as part of the supply agreement, since they vary with channel and volume.
Brushed motors fail at the brushes — a predictable, high-volume warranty event. Brushless drivetrains shift the failure curve away from that wear point, which protects both your service budget and your review scores.
