PU320DS Heavy Duty Large Diameter Precision Indexing Table with 60 Sec. Repeat Positioning Accuracy

PU320DS Precision Indexing Table Overview

The HONEPAN PU320DS precision indexing table is a heavy-duty cam divider engineered for large-diameter rotary indexing. Its generous table output and reinforced bearing system support wide fixtures and heavy loads while maintaining tight angular accuracy at every station, making it the flagship of our PU heavy-duty precision series.

Combining high torque transmission with precision-ground cam geometry, the PU320DS delivers repeatable station stops even under substantial off-center loads. It is the preferred choice for large indexing tables, heavy rotary fixtures, and precision dividers in demanding industrial applications.

Working Principle

The motor drives a large globoidal cam that engages the heavy-duty table output's needle rollers, advancing the dial through its station sequence. The cam's dwell section mechanically locks the table, holding heavy fixtures rigid while machining, assembly, or inspection operations proceed.

Key Features

• Large-diameter output for wide rotary fixtures
• Heavy-duty cam divider for high torque transmission
• Reinforced bearings handle high overturning moments
• Precision-ground cam for repeatable station stops
• Backlash-free mesh for consistent angular accuracy
• Mechanical lock eliminates drift under heavy load
• Configurable stations up to 16 positions

Technical Specifications

Note 1: Input shaft GD² is the dwell value. Note 2: C1~C5 values are allowable values at a safety factor of 2.

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 PU320DS?

The PU320DS features a Table 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 PU320DS supports 2, 3, 4, 6, 8, 12, 16 (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 60 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.
