A vendor blog ranks ten Chinese ball screw manufacturers, with Lishui Hengli Automation at number one and THK's China branch at number two. [S1]
For a specifying engineer, this list is a starting point for vendor outreach rather than a vetted shortlist. The piece is published on Hengli's own site, so ordering favors the publisher; cross-checking each candidate against independent catalogs, third-party test data, and lead-time performance is the only way to turn this roundup into a defensible supplier decision. The roundup also confirms which technical attributes (precision grade, load capacity, customization) the Chinese supply base is willing to discuss on the record, which sets expectations for RFQ responses.

What happened
A blog post titled "Best 10 Ball Screw Manufacturers in China 2025" was published on the Hengli Automation corporate site. The article is structured as a ranked countdown, with the first two entries fully detailed in the captured text and the remaining eight referenced only by position in the list. The publishing date shown at the top of the page is 2025-10-22, and the page identifies the author domain as hlt-cnc.com. The framing positions the list as a buyer guide for procurement teams sourcing linear motion components from Chinese suppliers. [S1]
Because the source is the website of the supplier ranked first, the roundup functions as both a market overview and a lead-generation asset for Hengli's own ball screw line. Readers should treat the ordering and the descriptive language as marketing-adjacent, and look for corroborating evidence on each named manufacturer before issuing an RFQ. [S1]
The names and claims given
Entry one is Lishui Hengli Automation Technology Co., Ltd. The article attributes three ball screw features to Hengli: high precision through advanced grinding, high efficiency from reduced friction versus lead screws, and long service life via heat treatment. The company advantages listed are customization capability, technical expertise from an in-house R&D team, and an unspecified "good reputation." [S1]
Entry two is THK Co., Ltd, specifically its China branch. The article credits THK with an advanced ball circulation design, high load capacity from large-diameter balls and optimized geometry, and low-noise operation achieved through precise manufacturing and special lubricants. The advantages listed are global brand recognition and a comprehensive product range. The captured text is cut off before the second advantage paragraph completes. [S1]
What it means for the ball screw category
For specifiers, the roundup confirms that Chinese suppliers are publicly competing on three axes: precision grade and backlash control, load capacity and speed ratings, and customization of size, pitch, and end machining. Hengli specifically calls out precision machining centers and semiconductor manufacturing equipment as target applications, while THK positions its China-made screws for heavy-duty presses, construction machinery, and medical equipment where noise matters. [S1]
The article does not cite any accuracy classes (such as C0, C1, or C3), dynamic load ratings, rated speeds, or life-test data for any of the ten manufacturers. It also does not name any specific THK or Hengli part numbers, leaving engineers to translate feature claims into measurable specifications through separate datasheet review. The shared application list (machine tools, robotics, aerospace, automotive) is repeated for multiple vendors, which limits its usefulness for differentiating suppliers. [S1]
How to check the primary source
The roundup itself is the primary source and is hosted at hlt-cnc.com. The article does not link to independent third-party test reports, certification bodies, or peer-reviewed performance data for any of the ten manufacturers. A specifying engineer should open each candidate's own corporate site, request ISO 9001 or IATF 6496 certificates, and ask for documented accuracy grade, dynamic load rating, and life expectancy curves before drawing a sourcing conclusion. The Lishui Hengli website listed in the article is hlt-cnc.com, the same domain that hosts the roundup, which reinforces the need to corroborate external claims independently. [S1]
