Description
Extract frozen kingpins and pull industrial mower drive sprockets with high-tonnage hydraulic hollow-bore power. The Power Team 20 Ton 6in cylinder industrial stroke RH series single acting ram delivers 40000 lbs of pulling force. This center-hole hydraulic ram features a hollow cylinder bore. It requires an external 10000 PSI pump and threaded pull rods to operate.
Heavy-duty carbon steel forms the cylinder housing and center-hole piston rod, resisting extreme tensile stress during pin pulling operations. A baked enamel exterior coating resists corrosion from harsh turf chemicals and wash-bay water. Precision bronze gland rings support the center tube, preventing internal metal-to-metal galling during uneven pulling setups. The heavy-duty internal spring retracts the steel piston rod once the release valve opens.
Key Features of Power Team RH206
Turf fleet technicians use this center-hole cylinder to draw seized pivot pins from commercial loader arms and mower decks. Threaded rods slide directly through the center bore.
- 20-ton hydraulic pulling capacity produces 40000 lbs of extraction force on frozen pins
- 6-inch hydraulic piston stroke pulls long commercial pivot pins in a single setup
- Center-hole design accepts threaded rods and cables for direct tensile pulling tasks
- Heavy-duty steel body construction withstands extreme mechanical stress without frame deflection
- Single-acting design with heavy spring return retracts the center piston rod automatically
- Industrial baked enamel finish protects the cylinder housing against corrosion and shop fluids
- 3/8-inch NPTF female coupler links with standard commercial shop hydraulic pump units
Center-Hole Hydraulic Dyno Load Telemetry
Tensile proof testing confirms 40000 lb holding force at 10000 PSI operating pressure with zero mechanical deflection. The effective cylinder piston area measures 4.14 square inches, demanding 24.8 cubic inches of oil for full stroke extension. Piston retraction cycle completes within 6 seconds under spring force. Center tube bore runout measures less than 0.002 inches under maximum operational pulling loads across hardened steel pull rods.
Pulling Setup Parameters Negative Operational Bounds
Pass high-tensile alloy B7 threaded rods through the center hole and secure them with hardened washers and grade 8 nuts. Center the cylinder body square against the work surface to eliminate side loading. Do not exceed the 6-inch stroke limit or side-load the center tube.
- Center bore internal surface requires light oil wiping to prevent rust formation
- Hydraulic coupler threads require thread sealant rated for 10000 PSI fluid systems
- Piston rod wiper seals require visual checks to stop dirt ingress into internal seals
Power Team Center-Hole Warranty Manifest
