330DA Precision Rotary Positioning Gearbox Overview

The HONEPAN 330DA precision rotary positioning gearbox delivers high-accuracy angular positioning for equipment that cannot tolerate drift or backlash. Its flange-type cam indexer design merges a precision cam, needle rollers, and a rigid output flange into a single compact positioning axis, offering the accuracy of a high-end rotary table with the simplicity of a mechanical drive.

Every cam profile is precision ground and inspected, ensuring consistent, repeatable positioning over a long service life. The backlash-free mesh maintains accuracy even under fluctuating radial and axial loads, making the 330DA ideal for precision machining fixtures, robotic positioning, and metrology turntables.

Working Principle

The 330DA converts continuous input rotation into precise intermittent output through a globoidal cam engaging the flange's needle rollers. The rolling contact produces minimal friction and wear, while the mechanical dwell lock holds the flange rigid at each indexed position, ensuring angular accuracy is maintained without servo holding torque.

FAQ — Frequently Asked Questions

1. What is a cam indexer and how does it work?

A cam indexer converts continuous motor rotation into precise intermittent (stop-and-go) rotary motion. A hardened globoidal cam engages needle roller followers on the output turret, advancing it one station per revolution and mechanically locking it during dwell — no electronic feedback, sensor, or brake is required.

2. What is the output type of the 330DA?

The 330DA features a Flange output, making it easy to mount dial plates, flanges, or fixtures directly. Its compact footprint integrates smoothly into automated assembly, packaging, and inspection workstations.

3. How many indexing stations are available?

The 330DA supports 2, 3, 4, 6, 8, 12 (customizable). We can also custom-grind the cam profile for a different station count or dwell angle to match your exact production sequence.

4. What is the indexing accuracy?

Indexing accuracy is ±30 Sec. with repositioning accuracy of ±4 arcsec (±2 arcsec). This mechanical precision is maintained over a long service life thanks to the backlash-free cam-and-roller design.

5. What load and torque can it handle?

Please refer to the Technical Specifications table above for the allowable radial/axial loads (C1–C3), bending force (C4), input torque (C5), GD² (C6), and weight. For safety, all C1–C5 values are rated at a safety factor of 2.

6. Can you customize stations, dwell angle, or mounting interface?

Yes. We customize the number of stations, driving angle, dwell angle, cam curve, and mounting interface to your requirements. Send us your dial diameter, station count, payload, and cycle time for a tailored recommendation.

7. What is the MOQ, lead time, and warranty?

MOQ is 1 piece. Standard models ship within 4–20 days, and custom configurations may take longer. Every unit carries a 1-year warranty, a 60,000-hour design service life, and lifetime technical support.

8. What industries use HONEPAN cam indexers?

Our cam indexers are widely used in automated assembly, filling and capping, packaging, inspection, and machining systems across the automotive, electronics, hardware, pharmaceutical, and food industries.
