Duty-Cycle Interpretation

Danfoss defines:

• Continuous: continuous operating rating
• Intermittent: permissible for approximately 10% of every minute
• Peak: permissible for approximately 1% of every minute

Therefore, 350–400 bar peak/intermittent values must not be presented as continuous operating pressure. The actual permissible pressure/flow combination must also be checked against the applicable motor function diagram.

Weight

The current Danfoss PowerSource page for 11026042 does not expose a weight attribute. Danfoss’s technical catalog lists weight by complete configuration code, demonstrating that motor weight varies with mounting, shaft and option configuration. Therefore, no unverified weight is assigned to 11026042 here.

TMT470 FL Configuration Reference

Danfoss’s official TMT FL documentation covers multiple mounting arrangements, including:

• 4-bolt flange configurations
• Ø125 mm pilot / Ø160 mm bolt circle
• Ø5 in SAE C / Ø6.37 in bolt circle
• Splined shafts
• 45 mm tapered shafts
• G3/4 ports
• 1-1/16-12 UN ports
• Drain connections
• Brake-release ports.

Published TMT470 FL dimensions vary by configuration. For example:

• Ø125 mm pilot / Ø160 mm bolt-circle configuration: L = 268.2 mm
• Ø180 mm pilot / Ø224 mm bolt-circle configuration: L = 260.0 mm
• US SAE C configuration: L = 287.0 mm.

These dimensions are configuration-family references, not confirmed final dimensions for 11026042.

Control Configuration

• Motor type: Fixed-displacement LSHT orbital hydraulic motor
• Hydraulic distribution: Disc valve with valve drive
• Orbital gear set: Geroler
• Displacement control: Fixed displacement
• Speed control: Hydraulic flow control
• Torque output: primarily determined by differential pressure and applied load
• Direction: controlled hydraulically through the working ports
• FLV configuration: includes a separate hydraulic brake-release circuit.

TMT FL Brake Specifications

Danfoss’s official TMT FL/TMTW FL brake section specifies:

• Holding torque: 2,000 N·m
• Minimum brake-release pressure: 13 bar / 190 psi
• Maximum continuous release pressure: 20 bar / 365 psi
• Maximum peak release pressure: 40 bar / 580 psi
• Brake-release chamber bleed-off: 0.65 L/min at 13 bar.

These values describe the TMT FL/TMTW FL brake platform. The exact brake option installed on 11026042 should be confirmed from the original configuration record before publishing it as an exact-part-number specification.

Key Technical Advantages

High Low-Speed Torque Density

The TMT470 provides 1,760 N·m continuous torque, 2,420 N·m intermittent torque and 2,735 N·m peak torque under the published operating conditions. This makes it suitable for high-load LSHT hydraulic drives.

Geroler Orbital Gearwheel Technology

Danfoss specifies a Geroler orbital gearwheel set with a disc valve and valve drive for the TMT platform. This architecture converts hydraulic pressure and flow into controlled rotary torque for low-speed applications.

Tapered Roller Bearing Support

TMT and TMT FL configurations use tapered roller bearings to support substantial radial and axial loading. Actual shaft-load limits depend on speed, load position, mounting flange and shaft configuration.

High Inlet Pressure Capability

For TMT250–630, Danfoss specifies:

• 270 bar continuous inlet pressure
• 370 bar intermittent inlet pressure
• 420 bar peak inlet pressure.

These values are not unrestricted simultaneous pressure/flow ratings; the relevant motor function diagram must be used for final system sizing.

High Return-Pressure Capability

With the appropriate drain-line arrangement, the TMT platform is specified for:

• 140 bar continuous return pressure
• 175 bar intermittent return pressure
• 210 bar peak return pressure.

Integrated FL Brake Platform

TMT FL/TMTW FL motors support integrated hydraulic braking, with published brake-release specifications and flushing-valve options. This makes the platform relevant to load-holding and high-duty mobile applications.

Multiple Mechanical Interfaces

Danfoss documents multiple mounting, porting and shaft configurations across TMT and TMT FL, including European, US, side-port, splined and tapered-shaft arrangements. Complete part-number verification is therefore essential for replacement engineering.

Engineering Data Boundary

The public Danfoss documentation reviewed here specifies architecture, displacement, pressure, speed, torque, bearing type and configuration families, but does not publish steel grades, heat-treatment hardness, surface-hardening depth or machining tolerances for 11026042. Those values should not be added without a component-level engineering document.

Application Areas

Typical TMT470 FLV applications include:

• Heavy-duty mobile machinery
• Road construction equipment
• Agricultural machinery
• Forestry equipment
• Material-handling equipment
• Conveyor drives
• Winch systems
• Rotary drum drives
• Wheel-drive machinery
• Industrial auxiliary drives
• Heavy-duty off-highway equipment
• High-load rotary systems

Danfoss positions its large orbital-motor platform for demanding mobile/off-highway applications and emphasizes high starting torque, robust design and substantial radial/axial load capability.

Expert Maintenance Tips

Manage the Drain Circuit

Large-displacement TMT motors must be evaluated not only at the A/B ports but also through their drain/return circuit. Excessive return pressure increases shaft-seal loading.

Respect the Duty Cycle

Do not treat intermittent or peak pressure values as continuous ratings. Danfoss limits intermittent operation to approximately 10% of every minute and peak loading to approximately 1% of every minute.

Control Oil Viscosity and Temperature

Danfoss’s TMT function diagrams are based on mineral hydraulic oil at 35 mm²/s / 165 SUS and 50°C / 120°F, with return pressure of 5–10 bar / 75–150 psi. Actual field performance will vary with oil temperature, viscosity and return pressure.

Calculate External Shaft Loading

The tapered-roller-bearing arrangement can support significant external loads, but allowable shaft loading must be evaluated from the actual:

• Shaft speed
• Load position
• Mounting flange
• Shaft design
• Output torque

Danfoss does not define one universal radial-load number for every TMT configuration.

Verify the FLV Brake Circuit

For FLV applications, separately verify:

• Brake-release pressure
• Brake-line restriction
• Drain pressure
• Holding torque
• Release response
• Oil temperature

The published TMT FL brake platform specifies 13 bar minimum release pressure, 20 bar continuous release pressure and 40 bar peak release pressure.

Verify the Complete 11026042 Configuration

For 11026042, do not purchase based only on “TMT470 FLV.” Verify:

• Complete part number
• Motor size
• Mounting flange
• Pilot diameter
• Bolt circle
• Shaft type
• Spline/taper/cylindrical dimensions
• Main-port configuration
• Drain port
• Brake-release port
• Shaft seal
• Bearing configuration
• Flushing configuration
• Rotation
• Installation envelope

Danfoss currently confirms the exact product identity but does not display all configuration attributes on the public 11026042 page, so the nameplate and original configuration record should remain the final replacement reference.

100% Simulated Working-Condition Testing

For a replacement TMT470 FLV, a practical final test program should include:

• No-load startup
• Forward/reverse rotation
• Low-speed stability
• Flow-response testing
• Continuous pressure-drop testing
• Intermittent pressure-drop testing
• Brake-release testing
• Drain-flow/return-pressure verification
• External leakage inspection
• Shaft-running verification
• Flushing-function verification where applicable

This gives the 100% Simulated Working-Condition Testing claim a concrete engineering basis.
