Hitachi Swing Drive (Without Motor)
Reliable Excavator Slew Drives – TOSOG

Heavy-Duty Hitachi Swing Drives Without Motor for Excavators

At TOSOG, we specialize in supplying high-quality Hitachi Swing Drives (without motor) engineered to deliver smooth, controlled upper-structure rotation, consistent torque transfer, and exceptional durability in the most demanding earthmoving, mining, and heavy construction environments. Our swing drives are designed to perform reliably under continuous duty cycles, high shock loads, vibration, and harsh operating conditions, making them suitable for both standard construction excavators and heavy-duty mining-class machines.

A Hitachi swing drive, also referred to as a slew drive or swing gearbox, is a mission-critical excavator drivetrain component responsible for converting the hydraulic output of the swing motor into rotational movement of the excavator’s upper structure (house). This assembly consists of precision-machined planetary gear sets, hardened shafts, high-load bearings, robust housings, and heavy-duty seals, all working together to ensure accurate, stable, and controlled rotation during digging, loading, lifting, and slewing operations.

By supplying the swing drive without the hydraulic motor, TOSOG provides a cost-effective, practical, and flexible repair solution for contractors, workshops, and fleet owners whose existing swing motors remain mechanically and hydraulically sound. In many real-world repair scenarios, the gearbox fails before the motor due to wear, backlash, bearing fatigue, or internal gear damage. Replacing only the swing drive allows customers to avoid unnecessary expenditure, reduce component waste, and significantly lower total repair costs while restoring full swing functionality.

Our Hitachi swing drives without motor are ideal for:

• Partial excavator overhauls

• Targeted swing system repairs

• Preventative maintenance programs

• Machine refurbishments and rebuilds

• Cost-controlled fleet maintenance strategies

TOSOG supplies a wide range of OEM-equivalent aftermarket swing drives, as well as tested used and surplus units, ensuring availability across multiple budgets and operational requirements. Each swing drive is selected with a focus on gear accuracy, load capacity, seal integrity, and compatibility with Hitachi swing motors, allowing for seamless integration and dependable performance once installed.

Whether you operate in open-pit or underground mining, civil and infrastructure construction, quarrying, bulk earthworks, or plant hire operations, TOSOG provides dependable Hitachi swing drive solutions that help minimize downtime, extend machine service life, and maintain productivity on site. We understand that excavator downtime directly impacts project timelines and operating costs, which is why our sourcing network and technical knowledge enable us to supply correct-fit swing drives quickly and reliably.

By choosing TOSOG, customers benefit from:

• Reduced capital expenditure through motor reuse

• Faster turnaround times compared to full swing motor assemblies

• Reliable swing performance under heavy load conditions

• Improved machine uptime and operational efficiency

TOSOG is committed to supporting the earthmoving and mining industries with robust, field-proven swing drive solutions that balance performance, reliability, and cost efficiency, ensuring your Hitachi excavators remain productive in even the toughest operating environments.

FAQs – Hitachi Swing Drive (Without Motor)

1. What is the difference between a swing drive and a swing motor?

The swing motor generates hydraulic power, while the swing drive (gearbox) converts that power into rotational movement of the excavator’s upper structure.

2. Can I reuse my existing swing motor?

Yes, provided the swing motor is in good working condition and compatible with the replacement swing drive.

3. Are aftermarket Hitachi swing drives reliable?

High-quality aftermarket swing drives are OEM-equivalent and widely used in mining and construction to reduce costs without sacrificing performance.

4. Do you supply used Hitachi swing drives?

Yes. TOSOG supplies tested used and surplus swing drives, subject to availability.

5. Do you offer installation support?

We provide technical guidance and fitment advice, but installation is typically done by your workshop or technician.

Buyer Tips: Choosing the Right Hitachi Swing Drive

🔧 Verify serial number compatibility – model alone is not enough
🔧 Inspect the swing motor before reuse
🔧 Check backlash and bearing condition
🔧 Replace seals during installation
🔧 Use correct hydraulic oil & torque specs

Following these tips will extend component life and prevent premature failure.
