Orbital Motors Manuacturer Hydraulic Motor Wholesale - ChangJia

Product Overview

1) Product overview

Product Features

- ChangJia 2000-series orbital (hydraulic) two‑speed motors for industrial mobile and stationary applications.

Product Value

- Displacements cover roughly 40–490 cm³/rev with high‑speed and low‑speed modes; maximum speeds up to about 1,000 rpm (model dependent), continuous pressure ratings up to ~205 bar and intermittent ratings higher.

Product Advantages

- Available in standard and bearingless versions, with configurable output shaft/flange and standard clockwise rotation (facing the output shaft).

Application Scenarios

2) Product features

- Pilot‑shiftable two‑speed design: user can change motor displacement (and therefore speed/torque) without altering input flow or pump pressure.

- Requires an external three‑way valve to switch pilot pressure between signal and low pressure; pilot port must be >3 MPa. Loaded pilot = double‑speed mode; unloaded = standard mode.

- Offers an optional closed‑center shuttle return for closed‑circuit installations.

- Mechanical details include involute spline shaft dimensions (14 teeth, 30° pressure angle) and a range of overall lengths and weights.

- In double‑speed the motor runs ≈1.8× the standard speed while delivering ≈0.45× the standard torque.

3) Product value

- Provides operational flexibility (two speeds) without added hydraulic complexity or extra pumps, improving machine productivity and adaptability on the fly.

- Reduces system cost and footprint by enabling speed/torque change through pilot control rather than mechanical gear changes.

- Compatible with standard 2K series data, simplifying integration and replacement in existing systems.

4) Product advantages

- Robust, factory‑controlled manufacturing with automated production equipment and QA processes for consistent quality.

- Proven design choices (attractive, serviceable designs and timely corrective actions) and options for customization (shaft/flange assembly to customer requirements).

- Wide model range and variants (standard/bearingless) let customers match performance, weight and installation needs.

- Suitable for both open‑ and closed‑circuit hydraulic systems.

5) Application scenarios

- Ideal for conveyors, winches and traction drives, augers and drilling/boring machines, piling rigs, irrigation and utility cable reels and similar industrial or mobile equipment.

- Especially useful where frequent changes in speed versus torque are required without redesigning the hydraulic supply (e.g., multi‑task machines, material handling and earthmoving equipment).
