110A-054-AP-E Parker Hydraulic Orbital Motor 89cc

Product Overview

The 110A-054-AP-E is a Parker 110A Series LSHT Hydraulic Orbital Motor, designed for low-speed, high-torque rotary drive applications where compact packaging, stable torque delivery and optional speed feedback are required.

Parker describes the 110A Series as a high-performance LSHT motor incorporating a pressure-loaded power element that compensates for internal leakage to maintain high volumetric efficiency. The design is also wear compensated, helping prevent normal wear from causing progressive loss of volumetric efficiency. Parker further specifies a one-piece solid fixed-axis shaft, which reduces spline contact stresses and permits rear-shaft integration for parking brakes, auxiliary drives or encoders.

For the 110A-054 displacement size, Parker specifies 89 cm³/rev (5.4 in³/rev). The published performance data includes 172 bar continuous / 207 bar intermittent maximum differential pressure, 60.6 L/min continuous / 83.3 L/min intermittent maximum oil flow, 716 rpm continuous data-point speed / 787 rpm maximum speed at maximum intermittent flow, and 199 / 241 N·m continuous/intermittent maximum torque.

The specific 110A-054-AP-E configuration is also identified by industrial parts documentation as a 1″ keyed, 2-bolt, NPTF, encoder motor configuration.

For replacement applications, engineers should verify the complete configuration rather than matching the 110A-054 displacement alone.

Key Technical Advantages

Pressure-Loaded, Wear-Compensated Power Element

The Parker 110A design uses a pressure-loaded power element to compensate for internal leakage and support high volumetric efficiency. The wear-compensated architecture helps maintain performance as operating hours accumulate.

One-Piece Solid Fixed-Axis Shaft

The one-piece solid shaft provides stable shaft-to-rotor engagement and reduces spline contact stress. The shaft architecture also supports rear-side integration of brakes, auxiliary drives or encoders.

Encoder-Ready Configuration

The E configuration provides an encoder mounting arrangement for applications requiring speed measurement or closed-loop speed control. This makes the 110A-054-AP-E suitable for applications where hydraulic torque generation and electronic speed feedback must operate together.

Balanced 054 Displacement

With 89 cm³/rev displacement, the 110A-054 provides a practical balance between flow demand, rotational speed and torque output. Parker’s data shows up to 787 rpm and 241 N·m intermittent torque for this displacement size.

Low Internal Pressure Drop

Parker highlights low internal pressure drop as a key design characteristic of the 110A Series. This supports higher mechanical efficiency and higher flow capability within the applicable operating range.

Compact and Rugged Architecture

Parker describes the 110A as a rugged and compact LSHT motor, making it suitable for mobile and industrial machinery where installation space and torque density are important design constraints.

Application Areas

The 110A-054-AP-E is suitable for hydraulic rotary-drive applications such as:

• Agricultural machinery
• Conveyor systems
• Material handling equipment
• Construction machinery attachments
• Hydraulic winches
• Rotary attachments
• Compact mobile hydraulic machinery
• Industrial rotary drives
• Machines requiring encoder-based speed feedback
• Auxiliary hydraulic drives

Expert Maintenance Tips

Verify the encoder configuration before installation.
The E suffix identifies an encoder mounting configuration. Confirm encoder compatibility, rear-shaft arrangement and available installation space before commissioning.

Respect continuous and intermittent ratings.
The 110A-054 is rated at 172 bar continuous and 207 bar intermittent differential pressure. Its corresponding maximum torque figures are 199 N·m continuous and 241 N·m intermittent. Parker states that intermittent ratings apply to approximately 10% of every minute.

Check radial shaft loading.
Parker’s service documentation states that the 110A Series is intended for long life under limited radial loading and directs users to the catalog radial-load limits. External sprocket, pulley or gear loading must therefore be included in the installation analysis.

Control hydraulic fluid condition.
Parker’s published test data is based on SAE 15W40 oil at 55 cSt and 54°C. Performance comparisons should take fluid temperature and viscosity into account.

Follow the Parker assembly procedure during service.
Parker recommends plugging open ports and the case drain before disassembly, cleaning the motor exterior, and lightly oiling seals, rollers and threaded bolt ends before assembly.

Verify the complete configuration for replacement.
Do not approve interchangeability based on “110A-054” alone. Confirm mounting, shaft, porting, encoder configuration, rotation and external loading before installation.
