THM – A2F – Rotary group and spares
Completely revitalize your heavy-duty hydraulic drives with THM A2F Series Rotary Groups and Spares. Specifically engineered for fixed displacement, bent axis piston pumps and motors, these premium rebuild kits provide the ultimate solution for restoring factory-level volumetric efficiency to your most punishing applications. Rather than discarding a rugged, expensive cast housing, your maintenance team can simply replace the internal rotating components—instantly eradicating internal fluid bypass and performance lag. Covering a versatile range of sizes from the compact 12 up to the massive 160, and including specific Right-Hand (R.H.) rotation models, these exact-tolerance drop-in parts ensure your heavy winches, industrial presses, and mobile drivetrains return to peak power and reliable operation.
Core Technical Specifications:-
- Component Architecture: Fixed Displacement Bent Axis Piston Pump/Motor Rotary Group
- Pump/Motor Compatibility: A2F Series Hydraulics
- Available Displacement Sizes: 55, 56, 63, 80, and 160
- Supported Models: A2F12 R.H., A2F45 R.H., A2F56, A2F63, A2F107, A2F160
- Available Spare Components: Bent axis cylinder blocks, tapered pistons with rings, valve plates, center pins, and drive shafts.
Key Features & Engineering Advantages
- Bent Axis Power Restoration: The robust A2F bent axis design is renowned for handling extreme pressures and high rotational speeds. Replacing the worn rotary group instantly restores the unit's ability to translate high-pressure fluid into massive mechanical torque.
- Exact OEM Drop-In Tolerances: Every piston, cylinder block, and valve plate is micro-finished to guarantee flawless compatibility. This ensures rapid run-in times and a perfect, leak-free seal within your existing A2F pump or motor castings.
- Specific Rotation Configurations: Includes highly specialized configurations like the A2F12 R.H. and A2F45 R.H. (Right-Hand rotation), ensuring you have the exact directional mechanics required for your specific machine drivetrain.
- Massive Cost & Time Savings: Protect your capital budget by rebuilding the internal "engine" of the hydraulic unit directly on the workbench, bypassing the long lead times and high costs associated with ordering a complete replacement assembly.
- High-Cycle Industrial Durability: Forged from premium, hardened metal alloys specifically treated to withstand the continuous shock loads, abrasive contamination, and brutal pressure hammering inherent in heavy industrial and mobile environments.
Ideal Industry Applications:-
The rugged, high-torque capabilities of A2F bent axis units make these rotary spares essential for:
- Heavy Marine & Offshore: Rebuilding the primary hydraulic motors driving heavy anchor winches, deck cranes, and specialized marine propulsion systems.
- Extreme Earthmoving: Restoring the high-speed track drives and swing motors on massive excavators, continuous miners, and heavy forestry equipment.
- Industrial Manufacturing: Servicing the fixed-displacement pumps powering heavy metal-forming presses, heavy-duty shearers, and automated extrusion machinery.
- Heavy Material Handling: Maintaining the robust lifting and driving circuits on large-scale industrial straddle carriers and high-capacity port cranes.
Why Choose THM A2F Rotary Spares?
- Uncompromising Torque: Fresh tapered pistons and perfectly matched cylinder blocks guarantee your motor delivers maximum twisting force under heavy loads.
- Sustainable Fleet Maintenance: Rebuild your heavy iron castings for a fraction of the cost of new units, drastically lowering your overall maintenance budget.
- Comprehensive Model Coverage: From the specialized A2F12 R.H. to the colossal A2F160, we supply the exact internal components your heavy machinery demands.
