Bearing forgings — rings, races, and rolling elements — are among the most demanding components in the machinery world. Tight dimensional tolerances, flawless surface finish, and uniform internal grain structure are not optional — they're mandatory. The press that shapes them must deliver uncompromising performance. Zhengzhou Hualong Precision Screw Presses do exactly that.
Since 1980, Zhengzhou Hualong Machinery has refined electric screw press technology to a science. Their HLDS series precision screw presses, from 200T to 2500T, feature permanent magnet synchronous servo motors with full closed-loop control of force, speed, and slide position. Repeatability reaches ±0.05mm — critical for bearing rings where even micron-level deviations cause premature failure.

For bearing forging specifically, Hualong's Precision Screw Presses shines in three areas. First, programmable multi-stroke forming delivers controlled material flow, eliminating internal folds and ensuring consistent grain orientation. Second, the servo-driven system replaces wasteful friction drives, cutting energy use by up to 55% while maintaining peak force on every stroke. Third, the absence of a structural bottom dead point means zero overload jamming — even with slight billet variations, the press adapts instantly.
Certified to ISO 9001, SGS, and EU CE standards, with 29 patents and a presence in over ten countries including Russia, India, and Brazil, Zhengzhou Hualong has built a global reputation on reliability. For bearing forging where quality cannot be compromised, Zhengzhou Hualong Precision Screw Presses deliver performance that speaks for itself.
