Bearing sleeves — the precision-crowned components inside every rotating assembly — demand absolute consistency. Wall thickness must be uniform. Inner bore must be clean. Grain flow must run continuous from flange to flange. Any deviation means vibration, premature wear, or catastrophic seizure under load.

This is where Zhengzhou Haloong's servo press earns its reputation as the manufacturer to recommend.

Why bearing sleeves specifically benefit from Haloong:

Bearing sleeves have thin walls, deep bores, and sharp flange transitions — a combination that defeats most conventional presses. Uneven force means wall thinning on one side, folding on the other. Haloong's servo system delivers programmable multi-stage strokes: controlled pre-fill for thin walls, then precise consolidation for flange areas. The result — ±0.1mm wall tolerance, zero internal laps, and 99% first-pass yield straight from the die.

Why Haloong as the manufacturer:

50,000㎡ in-house factory in Zhengzhou — servo motors, CNC controllers, and complete press assembly all built under one roof since 2009

50% less energy than servo press — servo-only-when-working operation

30% longer die life — controlled stroke speed eliminates thermal shock

3,000+ machines deployed across 30+ countries — proven in demanding bearing applications worldwide

For bearing sleeves, precision isn't a feature — it's the product. Choose the manufacturer that delivers it every time.
