Bohang Advantage: Achieving smooth displacement shifting in A6VM motors requires extreme precision in the valve plate and cradle bearings. Since 2008, Bohang has mastered the precise grinding technology needed to ensure our A6VM units shift seamlessly under load, matching the original control curves 1:1.
1. Wide Displacement Ratio: Seamlessly switch between high-speed travel and high-torque work modes.
2. Multiple Control Options: Available with HD, EP, and HZ controls to match your system requirements.
3. Compact Integration: Designed to fit into tight spaces in construction and mining machinery.
FAQ
Q: My machine jerks when shifting speeds. Is your A6VM control smooth?
A: Jerking is usually caused by a mismatch in the "Beginning of Control" pressure. Our A6VM motors are calibrated to follow the exact start-of-control curves of the original unit, ensuring a seamless transition between high-torque work and high-speed travel.
Q: Does the A6VM require a specific mounting orientation?
A: It can be mounted in any position. However, for the Bent-Axis design, it is critical that the motor case is filled with oil before startup. We recommend the "shaft horizontal" position with the drain port at the top for the best air venting.
Q: Which control types do you offer for the A6VM series?
A: We provide all standard controls: HD (Hydraulic Control), EP (Electric Proportional), and HA (Automatic High Pressure). All are calibrated to match the original displacement-to-pressure curves.
Q: Can this motor operate at zero displacement?
A: The A6VM is designed with a minimum displacement ($V_{g min}$) limit. We set this according to your specific machine requirements to prevent overspeeding and ensure lubrication.
Our Strategic Advantages
1. Decades of Specialized Expertise (Since 2008)
The Message: We aren't just a manufacturer; we are hydraulic pioneers. With nearly 20 years of dedicated focus on the Rexroth technical system, Foshan Bohang understands every internal tolerance and metallurgical requirement of axial piston units.
2. Premium Imported Raw Materials
The Message: Quality begins with the source. To match Rexroth’s durability, we exclusively use high-grade imported raw materials. From specialized alloy steels for cylinders and pistons to premium NBR/FKM (Viton) seal kits, our material selection ensures our products thrive in extreme high-pressure and high-temperature environments.
3. Standardized "Rexroth-Level" Manufacturing Process
The Message: We don't take shortcuts. Our production lines follow the exact standard operating procedures (SOP) and processing times as Rexroth. Each component undergoes precise heat treatment, nitrogenation, and grinding to ensure that our replacement units are 100% interchangeable and functionally identical to the original.
4. 100% Engineer-Verified Performance Testing
The Message: "Zero-Defect" is our goal. Before leaving the factory, every single unit is personally tested by our senior engineers on high-precision digital test benches. We verify volumetric efficiency, mechanical noise, and leakage rates under full load to guarantee "Plug-and-Play" reliability for your machinery.
5. The Best "Drop-in" Alternative in China
The Message: Foshan Bohang is committed to being the top-tier Chinese alternative to Rexroth. We bridge the gap between high-priced originals and low-quality aftermarket parts. Our mission is to provide global customers with the most cost-effective, high-performance axial piston pumps and motors that match the original installation dimensions perfectly.
