PM Bearing Press

How this press is built

The PM Bearing Press applies 585 Ton of rigid compressive force to produce backup rings & chevron packings (Engineered to client drawing envelope (Build HSE-280)). A variable displacement hydraulic circuit accelerates cycle times while maintaining a steady 121-second dwell under load. Regulated pressure bleed-off eliminates internal cleavage stresses prior to automated part ejection.

Material behaviour under compaction

Designed around the physical compressibility of sintered metal powder metallurgy alloy, this press handles standard free-flow and fine-cut resin grades. Rigid column construction prevents platen tilting during compaction, ensuring that preforms maintain consistent cross-sectional density and predictable sintering shrinkage factors.

Tooling and die design

Equipped with heavy-duty bolster plates with standardized T-slot spacing, the press accepts quick-change die assemblies. Mirror-polished die cavities (Ra ≤ 0.15 µm) and precision lower punch sleeves ensure effortless part release for backup rings & chevron packings.

Sizing and machine selection

For customized quotation of this 585 Ton PM Bearing Press, please provide part CAD files, material filler percentage, and target shift output. We calculate hydraulic cylinder dimensions, bolster clearances, and power pack ratings to ensure optimal production efficiency.

Quality checks and inspection

We execute thorough quality checks on every machine: 8-hour full-load hydraulic cycling, electrical panel dielectric safety testing, and dimensional inspection of trial-pressed components.

Installation and commissioning

Delivered with full engineering documentation: foundation layout, electrical schematics, hydraulic maintenance guides, and spare seal kits. Experienced HEMSUN technicians travel to your plant for turnkey setup and operator training.

Export packing and lead time

Our export department provides complete shipping documentation, customs compliance paperwork, and export packaging with corrosion-resistant barrier lining. Electricals are tailored to destination grid standards (415V/50Hz).

Maintenance and spare parts

Service procedures include periodic hydraulic oil filtering, daily bronze bushing lubrication, and annual hydraulic cylinder inspection. Factory-backed replacement seal sets are maintained in stock.

Safety and guarding

Safety architecture includes Category 4 optical guards, ergonomic two-hand activation buttons, hydraulic anti-drop check valves, and manual ram locking bars for die setup.
