TK0500T4631AAAA Parker TK500 Heavy Duty Motor

Product Overview

The Parker Torqmotor™ TK Series is a heavy-duty LSHT (Low-Speed High-Torque) orbital hydraulic motor platform engineered for high-torque, low-speed hydraulic drives and applications involving substantial external shaft loading.

Parker’s official Torqmotor documentation classifies TK as a Heavy Duty Torqmotor Series and provides TK250 through TK1000 displacement options. The published geometric displacements are approximately:

• TK250: 251 cm³/rev
• TK315: 315 cm³/rev
• TK400: 400 cm³/rev
• TK500: 500 cm³/rev
• TK630: 629 cm³/rev
• TK800: 800 cm³/rev
• TK1000: 1000 cm³/rev

The requested Parker configurations include:

• TK0500T4631AAAA
• TK1000K5640AAAA

The Parker product record identifies TK0500T4631AAAA as a TK500 and assigns Parker material number 45513865.

The TK1000K5640AAAA is identified as a Parker TK1000 configuration, with a published product weight of 39.10 kg.

The additional reference BMSYS-80-D-D does not belong to Parker TK Series. Public cross-reference data associates it with the Danfoss/Sauer-Danfoss OMSS 80, part number 151F0535, and it should therefore be handled as a separate orbital-motor replacement reference.

The publicly available cross-reference record associates BMSYS-80-D-D with Danfoss OMSS 80 / 151F0535. Exact pressure, speed, torque and weight data have not been assigned here because sufficient manufacturer-level documentation was not found during this verification.

Control Method

The Parker TK Series uses a fixed-displacement LSHT orbital architecture.

The basic hydraulic relationships are:

Hydraulic Flow → Motor Speed

Differential Pressure × Displacement → Output Torque

Therefore:

• Displacement: Fixed
• Speed Control: Hydraulic flow
• Torque Generation: Differential pressure
• Rotation: Reversing hydraulic flow
• Variable Displacement Control: Not integrated

The larger the displacement, the more torque can be generated at the same differential pressure, while the permissible speed generally decreases as motor size increases.

Key Technical Advantages

1. Heavy-Duty LSHT Powertrain

The TK platform is engineered for heavy-duty low-speed, high-torque operation.

Across TK250 to TK1000, displacement increases from 251 to 1000 cm³/rev while maximum speed drops from 520 to 220 rpm and continuous torque increases from 815 to 2410 Nm.

2. High-Strength Internal Powertrain

Parker classifies TK as a heavy-duty Torqmotor and provides a large-frame architecture for high torque transmission and demanding mechanical duty.

3. High External Shaft-Load Capability

The TK platform provides bearing and shaft-load engineering data for applications involving external radial forces.

This makes it appropriate for:

• Sprocket drives
• Chain drives
• Gear drives
• Wheel drives
• Conveyor systems

Parker also provides bearing-life calculation methods in the technical documentation.

4. High Torque Density

The TK1000 provides:

• 1000 cm³/rev
• 2410 Nm continuous torque
• 2660 Nm intermittent torque
• 220 rpm maximum speed

This output profile is well suited to heavy, low-speed rotary machinery.

5. Multiple Housing and Interface Configurations

The Parker TK family supports different housing, rear-port and coupling-shaft configurations.

Consequently, complete part-number verification is essential when replacing a TK500 or TK1000 motor.

6. Application-Specific Pressure Ratings

TK Series pressure capability varies by displacement size.

Examples include:

• TK250: 240/310 bar
• TK500: 205/275 bar
• TK630: 205/225 bar
• TK1000: 175/190 bar

This demonstrates why the exact displacement-specific performance table must be used for engineering approval.

Application Areas

TK250 / TK315

Typical applications include:

• Agricultural machinery
• Industrial conveyors
• Material handling
• Mobile equipment
• Rotary attachments

TK400 / TK500

Typical applications include:

• Heavy conveyor drives
• Agricultural machinery
• Forestry equipment
• Road machinery
• Sprocket drives
• Hydraulic winches
• Industrial rotary equipment

The TK500 configuration provides 500 cm³/rev displacement and 1440 Nm continuous torque, making it suitable for substantial low-speed drive loads.

TK630 / TK800

Typical applications include:

• Heavy-duty mobile equipment
• Large conveyor systems
• Forestry machinery
• Agricultural processing equipment
• Heavy material handling
• Industrial drives

TK1000 / TK1000K5640AAAA

Typical applications include:

• Heavy conveyor systems
• Car-wash conveyor drives
• Road construction machinery
• Large agricultural machinery
• Forestry equipment
• Heavy wheel drives
• Industrial rotary systems
• Sprocket-driven machinery

The Parker TK platform is also documented in conveyor-drive applications where low-speed, high-torque transmission is required.

BMSYS-80-D-D

BMSYS-80-D-D should be handled as a separate replacement reference associated with the Danfoss OMSS 80 / 151F0535 platform.

Expert Maintenance Tips

1. Match the Complete Configuration

Do not replace a motor simply by specifying:

TK500

or

TK1000

Verify:

• Full part number
• Displacement
• Housing
• Mounting
• Porting
• Shaft
• Rotation
• Rear-port arrangement
• Options

This is particularly important for:

TK0500T4631AAAA

and

TK1000K5640AAAA

2. Never Apply a Series-Maximum Pressure to Every Size

TK pressure ratings are displacement-specific.

For example, TK250 is rated at 240/310 bar differential pressure, while TK1000 is rated at only 175/190 bar.

3. Control TK1000 Operating Speed

TK1000 has a maximum speed of 220 rpm, with 151 L/min continuous flow and 227 L/min intermittent flow.

Pump flow must therefore be matched carefully to motor displacement and volumetric efficiency.

4. Calculate External Radial Loads

For sprockets, gears, pulleys and wheels, evaluate:

Radial Load + Load Distance + Shaft Speed + Bearing Life

rather than comparing torque alone.

Parker provides bearing-life calculation methodology for TK motors.

5. Control Hydraulic Shock

Heavy TK motors can be exposed to significant transient loads during:

• Sudden stopping
• Direction reversal
• Load impact
• Valve switching
• High-inertia acceleration

Relief and crossover protection should therefore be considered during system design.

6. Maintain Hydraulic Fluid Quality

Routine maintenance should monitor:

• Hydraulic-fluid cleanliness
• Filter condition
• Oil viscosity
• Oil temperature
• Return restriction
• Case pressure
• Internal leakage

7. Perform 100% Simulated Operating-Condition Testing

For replacement TK Series motors, recommended QA includes:

• Displacement verification
• Pressure testing
• Flow testing
• Speed verification
• Starting-torque testing
• Continuous-torque testing
• Internal-leakage testing
• Rotation-direction testing
• Shaft runout inspection
• Spline inspection
• Radial-load verification
• Bearing inspection
• Temperature-rise testing
• Noise and vibration inspection
• Complete configuration verification

For TK0500T4631AAAA, the corresponding TK500 verification baseline is 500 cm³/rev, 300 rpm, 205/275 bar, 114/151 L/min and 1440/1915 Nm. For TK1000K5640AAAA, the corresponding TK1000 baseline is 1000 cm³/rev, 220 rpm, 175/190 bar, 151/227 L/min and 2410/2660 Nm.
