Since 2008, ZOFANG has coordinated industrial transmission requirements across specified brands, China-made components and drawing-based parts. Model details, interfaces, inspection scope and delivery are confirmed item by item.
Branded, China-made and drawing-based parts can enter one enquiry. Each line retains its own model, drawing and acceptance basis.
Explore the full supply process| List item | Customer reference | Illustrative ZOFANG output |
|---|---|---|
| Branded bearing × 20 | Brand and complete model | Itemized branded-product quotation and supply terms |
| Linear rail / block × 8 | Model and rail length | China-made component scope and lead time |
| Custom timing pulley × 4 | Drawing revision | Machining points and quotation scope |
| Locating pins × 100 | Specification or drawing | Specification, inspection needs and lead time |
Output: itemized quotation, missing parameters and differences, item lead times, and combined or split shipment options.
Each product family keeps its own technical requirements. Procurement follows the relationships between the parts, with standard items and drawing-based work included in the same project list.
| Product family | Related components | Coordination points |
|---|---|---|
| Industrial bearings | Shafts, housings and locking parts | Full designation, dimensional series, clearance, seals and fits |
| Timing pulleys & belts | Motors, gearboxes, shafts and locking parts | Tooth profile, pitch, belt width, bores, keyways and connections |
| Linear guides | Blocks, mounting bases and screw drives | Series, block form, assembly height, rail length and mounting holes |
| Ball screws | Nuts, supports and couplings | Diameter, lead, usable travel, end machining and support interfaces |
| Racks & gears | Gearboxes, bearings and mounting structures | Module, tooth form, helix direction, mounting and mating geometry |
| Couplings | Motor shafts, screw ends and gearbox outputs | Shaft diameters, connection types, available space and operating conditions |
| Precision locating & fastening parts | Locating bores, fixtures, shafts and bases | Reference dimensions, fits, tolerances, threads and surface treatments |
| Servo motors | Drives, gearboxes and couplings | Specified model, flange, shaft end, feedback and brake configuration |
| Gearboxes | Servo motors, couplings, gears and pulleys | Ratio, input connection, output form and mounting dimensions |
Established domestic supply resources support sourcing around materials, dimensions, operating conditions and delivery requirements. Products from different sources retain their individual specifications and acceptance criteria.
Requirements for NSK, SKF, FAG, INA, HIWIN, TBI and other brands are reviewed against full part numbers. Suffixes, configurations, documentation and availability are confirmed for each line item.
Pulley bores, screw ends, locating parts and special fasteners are reviewed alongside the standard parts they connect to. Work follows the agreed drawing revision and technical requirements.
Brands, series, complete part numbers, configuration suffixes and drawing revisions are linked to the relevant items. Similar part numbers are not assumed to be interchangeable.
Shafts, bores, keyways, flanges, hole patterns and assembly heights are coordinated. Missing dimensions and interface differences are recorded separately; engineering selections and substitutions remain subject to approval.
Item quantities, quantities per machine, spares and delivery batches are aligned with the project list to help reduce assembly delays caused by mismatched arrival schedules.
Loads, speeds, travel, environment and installation space affect selection. Items requiring engineering calculations are assessed separately; unverified combinations are not presented as approved assemblies.
Items are organized by product family, brand and model, drawing revision and quantity, distinguishing standard components, specified brands and custom work.
Open technical points, supply scope, pricing, lead times and document requirements are tied to individual lines, making the quotation basis clear.
Procurement or custom work follows the confirmed order, with attention to critical-item progress and the interfaces between related parts.
Consolidated or staged shipments follow the agreed schedule. Item identification, quantities, packaging and accompanying documents are checked against the project list.
| Delivery consideration | Items to be agreed for the project |
|---|---|
| Item identification | List references, descriptions, brand and model or drawing revision, quantities and packaging labels |
| Custom-part acceptance | Critical dimensions, material, surface treatment, agreed inspection points and record format |
| Brand documentation | Model labels and available accompanying documents; availability and cost of additional records confirmed before ordering |
| Packaging | Protection, separation and packing arrangements appropriate to the parts and agreed transport requirements |
| Delivery schedule | Consolidated or staged shipments and the items that affect the assembly schedule |
Changes to models, quantities, drawings or process requirements are checked against the quotation, order and delivery plan. The agreed change record defines the revised scope.
Shortages, incorrect items, transport damage or specification differences are identified by order line and batch, with photographs, measurements and the actual condition informing the response.
Repeat purchases are checked against previously agreed models, drawings and acceptance requirements. Changes in the current requirement trigger a new review of the affected details.
A brand part number, a standard-component list or a custom drawing can be the starting point for your supply project.
