Linear Guide Support Brackets fix and secure parallel linear shafts or rails to machine frames, preventing deflection and maintaining parallel alignment across long spans. Designed for CNC machinery and automated guide systems, these brackets ensure rigid structural support under high dynamic loads. We manufacture both standard metric sizes (SK/SHF series) and custom-machined brackets built to exact engineering drawings.
Key Features
Rigid Clamping Design: Split-type or solid housing with integrated socket head cap screws ensures secure, even radial clamping force onto the shaft without surface distortion.
Precision Bore Alignment: Inner diameter and mounting base are CNC-machined in a single setup to maintain concentricity and parallel tolerance relative to the mounting surface.
Optimized Fastening Points: Counterbored or tapped mounting holes match standard T-slot and structural aluminum profile grids for fast, stable installation.

Body Material: High-grade extruded aluminum alloy (Standard: AL6061-T5 / AL6062) or Carbon Steel (upon request)
Dimensional Tolerances: Bore tolerance ±0.02 mm, mounting hole pitch ±0.05 mm
Surface Treatment: Natural anodized, silver/black electrolytic oxidation for corrosion and wear resistance
Materials & Machining Processes
Material Selection: Certified aluminum alloy billets selected for high tensile strength-to-weight ratio and dimensional stability. Material test reports (MTR) provided upon request.
CNC Machining Workflow:
Saw Cutting: Raw extruded bars cut to precise blank lengths with minimal burrs.
CNC Turning / Boring: Center bores machined to exact diameter and surface finish (Ra ≤ 1.6 μm) to prevent shaft scoring.
CNC Milling & Drilling: Base faces, slotting cuts, and bolt holes executed on multi-axis vertical machining centers (VMCs) to guarantee geometric tolerances.
Deburring & Cleaning: Ultrasonic cleaning removes residual cutting fluids and aluminum chips.
Applications
CNC Routers & Engraving Machines
Supporting gantry rails and lead screw/linear shaft assemblies.
Industrial Automation
Automated guided vehicles (AGVs), pick-and-place modules, and sorting arms.
Test & Measurement Rigs
Optical inspection benches and linear slide stages requiring smooth, deflection-free motion.
Packaging & Textile Machinery
High-speed reciprocating guide systems.
Customization & OEM Services
Build-to-Print Manufacturing: Production executed strictly according to customer 2D/3D CAD drawings (STEP, IGES, PDF).
Dimensional Customization: Non-standard bore diameters, altered mounting hole patterns, extended bracket lengths, and specialized cutout pockets.
Material & Finish Options: Available in stainless steel (SUS304/SUS316) or custom powder coating / hard-coat anodizing.
Prototyping & Volume Production: Rapid prototype sampling available within 7–10 days; scalable production lines supporting batches from 100 to 50,000 units.
Quality Control & Inspection
Incoming Material Inspection
Spectral analysis and hardness testing verify raw alloy composition before production.
In-Process Inspection
CNC operators perform First Article Inspection (FAI) using digital calipers and micrometers every 50 parts.
Final Dimensional Audit
Key features-including bore diameter, center height from base, and hole spacing-verified using coordinate measuring machines (CMM) and pin gauges.
Documentation
Inspection reports, dimensional checksheets, and RoHS compliance certificates shipped with every lot.
Packaging & Shipping
Anti-Corrosion Measures: Components coated with protective anti-rust oil (for steel) or separated with interleaved PE film (for aluminum) to prevent surface oxidation.
Packaging Structure: Individual plastic bagging, layered corrugated inner dividers, and heavy-duty double-wall export cartons packed on fumigation-free wooden pallets.
Logistics Support: Air freight, express courier (DHL/FedEx), and sea freight options available with complete export clearance documentation (Packing List, Commercial Invoice, Certificate of Origin).
Frequently Asked Questions
Q: What is your Minimum Order Quantity (MOQ)?
A: Standard catalog sizes have no strict MOQ for stock items. Custom OEM brackets typically require an MOQ of 100 pieces per size/specification.
Q: What is the standard lead time for production?
A: Stock samples ship within 3 working days. Custom production runs take 15 to 25 days depending on batch volume and anodizing requirements.
Q: What 2D/3D file formats do you accept for custom orders?
A: We accept STEP, IGES, DXF, DWG, and PDF engineering drawings with explicitly stated tolerances and thread callouts.
Q: Can you laser etch our company logo or part numbers on the brackets?
A: Yes, laser marking for part numbers, batch codes, or logos is available at no extra charge for volume orders.
Q: How do you ensure the clamp bore does not damage the linear shaft?
A: All internal bores undergo precision boring and edge-breaking (chamfering) to eliminate sharp burrs that could score precision ground shafts.
Q: Are material certificates provided with the shipment?
A: Yes, Mill Test Certificates (MTC) and dimensional inspection sheets are included in the shipping documents.
