Building linear axes from loose rails, screws and brackets costs days of alignment per axis and varies station to station. This solution delivers pre-assembled, inspection-backed linear motion systems - slide modules, cross tables and dual-shaft units - from one accountable factory.
Integrators and machine builders who assemble linear axes from loose components pay a hidden tax on every build. Rails, screws and brackets arrive from different sources, so every axis starts with days of alignment work. Repeatability varies station to station, and when something fails there is no single supplier to call. Precision stations suffer the worst: unverified orthogonality on cross tables costs a calibration day per unit before production can start.
Dongfeng assembles the complete axis under one roof: guideway, ball screw, aluminum base and motor mounts come pre-aligned and inspected as one unit. The SKF20 module integrates an HGR15 guideway and SFU1605 screw on a 2020-compatible base; XY200 cross tables ship with CMM-verified 90-degree orthogonality within 0.02 degrees; SBR/SBS/TBR units cover round-rail axes from 18 mm low-profile to 3 m heavy gantry spans.
Who / what: a lab-automation integrator needed 12 repeatable X-axes for a microplate handling system. Problem: assembling axes from loose rails, screws and brackets consumed integration weeks and introduced alignment errors.
Where the numbers come from: the integrator's project time sheets and per-station repeatability test records at system acceptance.
Source: integrator's acceptance test documentation shared at contract close.
Who / what: a photonics manufacturer required orthogonal X-Y positioning under a microscope station. Problem: generic cross tables arrived with unverified orthogonality, costing a calibration day per unit.
Where the numbers come from: the CMM certificates included per unit, spot-checked against the customer's own calibration equipment.
Source: per-unit CMM report cross-verified by the customer's metrology lab.
Who / what: a technical-college supplier builds desktop CNC kits from individual components. Problem: students spent assembly time fighting rail-shaft misalignment instead of learning motion control.
Where the numbers come from: the supplier's semester-by-semester support ticket counts.

System-level buyers should request the module inspection sheet (orthogonality, flatness, repeatability) together with the standard certificate pack when ordering.
SKF20 aluminum profile linear motion slide module integrating HGR15 guideway, SFU1605 ball screw, and 2020 T-slot compatible aluminum base into one pre-assembled unit. 11.2 kN dynamic load, 500mm standard travel. Designed for lab automation, pick-and-place, and desktop CNC integration with aluminum extrusion frames.
XY200 precision cross-slide table with dual HGR15 guideway and SFU1605 ball screw drive, CMM-verified 90°±0.02° orthogonality, and ground base plate flatness ≤0.01mm. 200mm travel per axis, ±0.01mm repeatability. Designed for optical alignment, micro-assembly, and precision measurement equipment.
SBR16 integrated linear motion guide unit combining hardened GCr15 shaft, aluminum support rail, and double-row bearing block. Pre-assembled and ready to bolt on — 7.8 kN dynamic load at 16 mm shaft diameter. Designed for DIY CNC routers, desktop engravers, and educational automation builds.
SBR20 heavy-duty integrated linear motion guide unit with 20 mm shaft and dual bearing blocks, delivering 11.2 kN dynamic load per block (22.4 kN per axis). Standard lengths to 3000 mm. Designed for mid-size CNC routers, plasma cutting tables, and woodworking gantry machines.
TBR16 synchronized dual-shaft linear motion guide system with single carriage spanning two parallel 16 mm shafts. Delivers 15.6 kN dynamic load and 2× moment resistance for cantilevered axes. Designed for pick-and-place equipment, automation gantries, and synchronized motion applications.
SBS16 single-axis low-profile linear motion slide unit with 18mm total system height - 40% lower than SBR16. Integrates 16mm hardened shaft, aluminum support rail, and low-profile bearing block delivering 5.2 kN dynamic load. Designed for desktop 3D printers, laser engravers, and compact automation equipment.
When alignment time and cross-station consistency cost more than the module premium. Pre-assembled units arrive with guide and drive already aligned on the base, so integration becomes mounting plus wiring.
XY200 ships with CMM-verified 90-degree orthogonality within 0.02 degrees, base flatness at or under 0.01 mm, and 0.01 mm repeatability per axis over 200 mm travel.
The SKF20 aluminum-profile module covers 500 mm standard travel with an 11.2 kN dynamic capacity and motor-mount interfaces for common steppers and servos.
Yes. Travel length, screw lead, guide series and motor-mount pattern are configured per order; OEM/ODM projects can also request custom base profiles.
Yes. The same rails, screws and carriages used inside the modules are available as components, so a mixed build keeps one material and quality source.
