Buyer's Digest

Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Motors And Drives. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.

Original product description

This hydraulic slewing drive is designed to transmit rotary forces and high torque in a compact, ready-to-mount module. Its described construction combines a slewing bearing, worm shaft, housing, bearings and motor.

The motor drives the worm shaft, rotating the outer ring of the slewing bearing to deliver torque through the flange while the inner ring remains fixed in the housing. The stated design is intended for low-speed, high-torque duties.

Supported application examples include construction and agricultural machinery, loading and truck-mounted cranes, lifting platforms, special vehicles, excavator attachments, rotary platforms and solar tracking systems. A hydraulic motor is identified as the power source for construction-machinery configurations.

One published Socare 1 configuration lists a 71:1 gear ratio, 1.46 kN·m output torque, 13.5 kN·m tilting moment torque, 10.4 kN·m holding torque and 40% efficiency. Its stated static ratings are 133 kN axial and 53 kN radial, while its dynamic ratings are 32 kN axial and 28 kN radial.

Listed materials for that configuration are 42. CrMo and 50. Mn. The source also presents separate WD Series 12 overview values, including 1.47 rpm output speed, 12.24 kN·m output torque, 72.3 kN·m holding torque and 135.6 kN·m tilting moment torque.

These figures appear to describe a different size or configuration and should not be combined with the Socare 1 ratings when specifying an order.

Published construction features include worm-gear meshing, a double-skeleton oil-seal structure stated to reach IP65, and galvanized or QPQ surface treatment for the slewing bearing. Horizontal installation and a single-step bevel-gear description are also listed in the overview.

Because customization is available, buyers should request a model-specific technical drawing and confirmed data sheet before procurement.

Procurement confirmation should cover the exact model and size, required torque and load ratings, operating speed, gear ratio, mounting orientation, flange and bolt pattern, hydraulic motor details, pressure and flow requirements, rotation range, backlash, duty cycle, operating temperature and environmental exposure.

Buyers should also confirm whether the quoted unit includes the hydraulic motor, which surface treatment and sealing configuration will be supplied, and which documents or conformity records apply to the ordered model.

Buyer tips

  • State quantity range and split-delivery needs before price comparison.
  • Add certification, material or inspection standards when they affect acceptance.
  • For time-sensitive projects, include target arrival date and destination.
  • For special applications, describe operating condition, installation environment and duty cycle.

FAQ

What should buyers confirm first?

Confirm application, specification, quantity, destination and lead-time requirements before comparing offers.

Can buyers inquire when specs are incomplete?

Yes. Add model, material, size, use case and inspection needs in the RFQ to make replies comparable.

How should this listing be evaluated?

Check title, category, specifications and related keywords against the actual sourcing requirement.
