Bosch Rexroth A6VM & A6VE Series Variable Displacement Hydraulic Motor Parts & Rotary Group

Key Specifications

Overview

HYLINK supplies precision-engineered Bosch Rexroth A6VM series (A6VM28, 55, 80, 107, 140, 160, 200, 215, 250, 355, 500, 1000) and A6VE series (A6VE28, 55, 80, 107, 160, 200, 250) bent-axis axial piston variable motor replacement parts and complete rotary group overhaul kits. Fully compatible and 100% interchangeable with original Bosch Rexroth components, every part is manufactured to exact factory specifications and thoroughly inspected before shipment. This provides a reliable, cost-effective maintenance solution for hydraulic repair facilities, distributors, and equipment service operators.

Product Overview

The Bosch Rexroth A6VM (standard mounting flange) and A6VE (plug-in design for direct gearbox integration) variable displacement bent-axis motors are widely used in demanding hydrostatic drive systems. Operating under high system pressures and frequent speed/torque changes, internal rotating components—including the drive shaft with pistons, cylinder block, valve plate, bearing plate, and center pin—undergo continuous mechanical friction and shock loading. Over extended operating hours, surface wear can lead to diminished output torque, internal fluid bypass, elevated oil temperatures, and loss of drive power.

HYLINK manufactures high-precision complete replacement rotary groups and individual components for the full range of A6VM and A6VE motor frame sizes. Built from high-strength forged alloy steel and wear-resistant materials, each part undergoes micro-precision CNC machining and 3D CMM quality inspection. This enables service technicians to rebuild worn rotating assemblies directly without replacing the main housing or complete motor assembly, significantly cutting repair expenditure and reducing machinery downtime.

Available Components

Below is the standard component list for Bosch Rexroth A6VM and A6VE series hydraulic motors. Individual spare parts and complete overhaul repair kits are both available:

Quality Assurance & Manufacturing

Every HYLINK pump and replacement part undergoes strict quality control before shipment:

l Dimensional accuracy — checked with high-precision CMM (Coordinate Measuring Machines) to guarantee an exact fit with original pump housings.

l Material metallurgy — manufactured from premium forged steel and high-wear-resistant alloys to prevent premature fatigue.

l 100% performance test — every complete pump assembly is tested on our dynamic hydraulic test rig for pressure, flow rate and efficiency under full working load.

Packing, Shipping & Warranty

l Packaging — anti-rust protective film + heavy-duty foam cushioning + standard export fumigation-free wooden case (reinforced carton for small spare parts).

l Shipping — express courier (DHL / FedEx) for urgent repair orders; sea or air cargo for bulk orders.

l Warranty — 6 months quality assurance against manufacturing and material defects from the delivery date. In the event of a confirmed quality defect, HYLINK provides hassle-free replacement.
