Ball Screw Support Units with Precision Alignment
A factory confirms they can deliver C5-grade ball screw support units in six weeks, but at week five they request an extension because grinding tolerances failed the first inspection. Your production line waits another three weeks while they rework the batch - and when the shipment finally arrives, the material certificates show a different steel grade than specified. Incoming quality rejects the entire order, and you're back to square one with a stalled assembly schedule and no backup supplier queued.
That scenario is avoidable. All participating manufacturers here pass verification checks for business licenses, equipment confirmation, and baseline certifications before listing products or responding to requests. Each factory profile displays years in operation, employee count (50 to 500+ workers), quality control staff size, export percentage, and general product categories with price ranges. Tolerance capabilities, specific certifications like IATF 16949 or ISO 3408 compliance, and inspection reports come through direct factory contact or within RFQ responses.
Chinese manufacturers producing support units for ball screws used in CNC machines, robotics systems, and aerospace actuators show equipment capacity, employee count, and product ranges.
When you're ready to compare, contact suppliers directly to discuss specifications and negotiate pricing, or submit a Request for Quotation (RFQ) with your technical drawings, tolerance requirements (accuracy grades C5 to C7 per ISO 3408), and material specifications to receive multiple comparable quotes within roughly 24 hours.

Frequently Asked Questions
Is Haizol a Reliable Way to Source Ball Screw Support Units From China?
Haizol has run as a China-specialist sourcing platform for over 10 years and holds a 4.8/5 Trustpilot rating from verified buyers, a fair proxy for reliability when sourcing ball screw support units. Factories in the directory are verified generally before listing, and you deal with them directly rather than through Haizol as a price middleman. Ask a shortlisted factory for its grinding inspection report and material certificates covering the C5-grade tolerance and steel grade you need, since that verification happens between you and the manufacturer directly. A dedicated account manager is available free if you'd rather compare several quotes side by side.
How Do I Verify a Factory Can Hold C5-Grade Tolerances on Ball Screw Support Units?
Request the grinding inspection report showing pitch accuracy and straightness measurements against ISO 3408, along with the measuring equipment used - laser interferometer or coordinate measuring machine. Ask for material certificates confirming steel grade (GCr15 or 9Cr18) with batch traceability, plus preload consistency test data, before committing to a production run.
What Certifications Should I Request Beyond ISO 9001 for Ball Screw Support Units?
For automotive or robotics applications, ask whether the factory holds IATF 16949 certification. If units are exporting into the EU, request RoHS compliance documentation. Confirm ISO 3408 compliance specifically covers the accuracy grade you ordered (C5 through C7), since that standard governs assembly tolerances rather than the factory's general quality system.
What Are Realistic Lead Times for Ball Screw Support Units, and How Do I Avoid Grinding Rework Delays?
Standard C6/C7 grade units typically ship in 4-6 weeks; tighter C5-grade tolerances commonly extend production to 6-8 weeks due to additional grinding and inspection passes. Request first-article inspection reports at the production midpoint, not just before shipment, so grinding tolerance failures surface with enough time to rework the batch rather than forcing an extension late in the schedule.
How Do I Verify Material Grades When Sourcing Ball Screw Support Units From China?
Request mill certificates for the specific steel grade named in your RFQ (GCr15 bearing steel or 9Cr18 stainless), matched to the batch number on the shipped parts. Cross-check this against the material grade stated in the initial quote - a mismatch discovered on arrival, rather than verified before production starts, is the most common quality failure reported for this component category.
