About VICKERS

Vickers is a hydraulic equipment brand with a long history in fluid power technology. The brand originated in the United States and became known for developing vane pumps, motors, and valves used in industrial and mobile hydraulic systems. Over the decades, Vickers products have been specified in applications requiring reliable conversion of hydraulic pressure into rotary mechanical power. Today, the Vickers line includes hydraulic motors, pumps, valves, and couplings, with a focus on standardized mounting and port configurations that simplify integration into existing systems.

3G Electric supplies Vickers hydraulic components to plant engineers, maintenance managers, and procurement specialists worldwide. The current inventory includes Vickers J Series hydraulic motors, which are positive-displacement motors that convert hydraulic fluid pressure into torque and rotation. These motors are available in several displacements, ranging from 0.5 cu in/rev to 3.0 cu in/rev, with maximum speed ratings from 393 RPM to 1,992 RPM and pressure ratings up to 2,030 psi. All listed J Series motors use a 5-bolt mounting flange, 1/4"-28 UNF mounting threads, and 9/16"-18 UNF port connections. This consistency in mounting and porting allows interchangeability across the series without modifying manifolds or brackets.

The J Series motors are intended for industrial fluid power systems where compact size and defined performance characteristics are required. Typical uses include driving fans, conveyors, mixers, and other rotating equipment in manufacturing, processing, and material handling environments. The motors operate with hydraulic oil and are rated for continuous or intermittent duty depending on the specific displacement and speed combination. Because the motors are positive-displacement type, output speed is proportional to flow rate, and output torque is proportional to pressure differential.

3G Electric supports the Vickers line by maintaining stock of these motors and providing technical specifications for each part number. The product data includes displacement, maximum speed, pressure rating, mounting type, and port sizes, allowing buyers to match the motor to their hydraulic circuit requirements. For plant engineers and maintenance personnel, this means access to replacement motors that meet the original equipment specifications without requiring system redesign. Procurement specialists can use the published specifications to verify compatibility with existing Vickers motors or to select a motor for a new installation.

The Vickers J Series motors are built to standard hydraulic industry practices, with cast iron or steel housings and precision-machined internal components. While specific IP ratings are not provided in the available product data, the motors are intended for installation in protected industrial environments. They are not designed for direct exposure to washdown or corrosive atmospheres without additional protection. The 5-bolt mounting pattern and UNF threads are common in North American hydraulic systems, and the 9/16"-18 UNF port size accepts standard hydraulic fittings.

3G Electric ships Vickers products globally, serving customers in manufacturing, energy, and process industries. The company provides part number cross-referencing and specification verification to help buyers confirm that the selected motor matches their application. For maintenance and repair operations, having access to these motors with published performance data reduces downtime and ensures that replacement parts meet the original design intent. The Vickers J Series motors listed are available with manufacturer part numbers 129-0458, 129-0342, 129-0293, 129-0339, 129-0291, 129-0470, 129-0341, and 129-0340, covering a range of displacements and speed ratings.

Frequently asked questions

Common questions about VICKERS from 3G Electric.

What are the mounting and port specifications for Vickers J Series hydraulic motors?

Vickers J Series hydraulic motors use a 5-bolt mounting flange with 1/4"-28 UNF mounting threads. The port connections are 9/16"-18 UNF. This mounting and port configuration is consistent across the J Series models listed, including those with displacements from 0.5 cu in/rev to 3.0 cu in/rev. The 5-bolt pattern and UNF threads are standard in many North American hydraulic systems, allowing direct replacement without adapter plates. When ordering, verify that your manifold or bracket matches the 5-bolt pattern and that your fittings are compatible with 9/16"-18 UNF ports.

What is the maximum pressure rating for Vickers J Series hydraulic motors?

The maximum pressure rating for Vickers J Series hydraulic motors varies by displacement. Models with 0.5 cu in/rev, 0.8 cu in/rev, and 1.2 cu in/rev displacements are rated to 2,030 psi. The 1.9 cu in/rev model is rated to 1,750 psi, and the 3.0 cu in/rev models are rated to 1,400 psi. These ratings reflect the continuous duty pressure limit for each displacement. Operating above the rated pressure may reduce service life or cause internal damage. Always confirm the pressure rating of the specific part number before installation.

How do I select the correct Vickers J Series motor displacement for my application?

Selection depends on required output speed and torque. For a given hydraulic flow rate, a smaller displacement motor will turn faster but produce less torque per unit of pressure. For example, the 0.5 cu in/rev model reaches 1,992 RPM at maximum rated flow, while the 3.0 cu in/rev model reaches 393 RPM. If your application requires high speed and low torque, choose a smaller displacement. If it requires low speed and high torque, choose a larger displacement. Also consider the pressure rating: higher displacement models have lower maximum pressure. Match the motor's continuous pressure rating to your system's operating pressure.

What are the speed ratings for Vickers J Series hydraulic motors?

Maximum speed ratings for Vickers J Series motors range from 393 RPM to 1,992 RPM. The 3.0 cu in/rev models (MPN 129-0458 and 129-0470) are rated to 393 RPM. The 1.9 cu in/rev model (MPN 129-0342) is rated to 650 RPM. The 1.2 cu in/rev models (MPN 129-0293 and 129-0341) are rated to 1,043 RPM. The 0.8 cu in/rev model (MPN 129-0340) is rated to 1,575 RPM. The 0.5 cu in/rev models (MPN 129-0339 and 129-0291) are rated to 1,992 RPM. These speeds are maximum values; actual speed depends on flow rate and load.

Are Vickers J Series hydraulic motors suitable for continuous duty?

Vickers J Series hydraulic motors are rated for continuous duty at pressures up to their published maximum pressure rating. However, continuous operation at maximum pressure and speed may affect service life. For extended life, operate at or below 80% of the maximum pressure rating and ensure proper filtration and cooling of the hydraulic fluid. The motors are positive-displacement type and can be used in both continuous and intermittent duty applications. Always refer to the specific part number's specifications and consider the duty cycle of your application when selecting a motor.

What is the difference between Vickers J Series motors with the same displacement?

Vickers J Series motors with the same displacement may have different manufacturer part numbers due to variations in shaft type, port configuration, or internal features. For example, MPN 129-0293 and MPN 129-0341 both have 1.2 cu in/rev displacement and 2,030 psi rating, but they are distinct part numbers. The differences may include shaft diameter, keyway, or mounting flange details not fully captured in the summary specifications. When replacing a motor, always match the manufacturer part number exactly or verify that the alternative has identical mounting, shaft, and port dimensions. Consult the detailed product data for each part number.
