Hollow-Core Cylinders
Hollow-Core Hydraulic Cylinders are engineered for applications requiring both pushing and pulling capability, making them one of the most versatile tools in industrial force operations. Featuring a central through-hole, these cylinders allow tension rods, cables, studs, and bars to pass directly through the piston—enabling efficient bolt tensioning, pulling, extraction, and controlled lifting tasks. Built with high-strength alloy steel and enhanced with precision-machined components, they deliver reliable performance under demanding loads and harsh working conditions.
Technical Specifications:
Cylinder Capacity : 10-100 ton.
Stroke : 50-150 mm.
Closed Height : 90-200 mm.
Material : Steel.
Applications:
- Lifting, aligning, and positioning components where through-rod access is required.
- Pre-stressing and post-tensioning of anchors, studs, and threaded fasteners.
- Controlled pulling and pushing tasks in fabrication and repair workshops.
- Flange spreading, separation, and controlled opening in pipework systems.
- Precision extraction and tensioning during refinery, pipeline, and plant shutdowns.
- Assembly and disassembly of heavy machinery and industrial components.
- General industrial force applications requiring combined push-pull capability.
Key Features:
Uses hydraulic pressure for extension and an internal spring for automatic retraction, ensuring simple, reliable, and efficient one direction force application.
Allows both push and pull operations using tension rods, cables, or fixtures inserted through the centre bore—ideal for tensioning, pulling, lifting, and extraction tasks.
Precisely machined collar threads are designed to safely absorb the cylinder’s full rated load, enabling secure mounting and stable load handling in demanding applications.
Bronze-reinforced stop ring and base significantly increase side-load resistance, improving operational safety and extending the working life of the cylinder.
Manufactured with high-strength alloy steel to ensure dependable load-bearing performance, even under repeated heavy-duty industrial use.
Smooth internal surfaces and accurately machined parts ensure consistent movement, enhanced efficiency, and reduced wear during long-term operation.
High-performance seals minimize hydraulic leakage and protect internal components from contamination, maximizing reliability in tough environments.
Capable of lifting, pushing, pulling, tensioning, installing, and removing components—offering multifunction capability in a single compact tool.
