Key Applications

Automotive Assembly Lines

Engine assembly, transmission assembly, axle assembly, dashboard assembly, and final trim lines all rely on precision indexing tables. Our roller cam tables handle cycle times as fast as 1.2 seconds per station, carrying fixtures with components up to 100 kg. The through-hole design passes air lines for pneumatic clamps and vacuum pickups.

Electronics Manufacturing

Smartphone assembly, PCBA testing, battery cell assembly, and semiconductor packaging require ultra-clean, high-speed, precise indexing. Our direct drive tables index in 0.3 seconds with ±0.2 arc-min repeatability. Zero backlash ensures delicate components are not jarred during acceleration or deceleration.

Pharmaceutical & Medical Device Assembly

Syringe filling, vial capping, inhaler assembly, and surgical instrument packaging demand contamination-free, washdown-compatible equipment. We offer stainless steel or coated tables with IP65 sealing, smooth surfaces without crevices, and FDA-compliant lubricants. Index times are adjustable from 0.5 to 3 seconds to match filling and inspection cycles.

Food & Beverage Bottling/Capping

Rotary filling lines, capping machines, and labeling stations need high-speed, wash-down duty tables. Our worm gear tables with stainless steel hardware and sealed bearings withstand daily high-pressure washdowns. Index times of 1–2 seconds match typical filling machine speeds of 30–60 bottles per minute.

Packaging Lines

Carton erecting, product loading, case packing, and palletizing often use indexing tables to present containers to multiple packaging stations. Our larger diameter tables (1,000–1,600 mm) handle multiple lanes of product simultaneously.

Battery & Energy Storage Assembly

Prismatic cell assembly, pouch cell stacking, and module assembly require clean, precise indexing with moderate load capacity. Our roller cam tables with through-hole design allow vacuum and electrical pass-through for testing probes at each station.

General Industrial Automation

Any rotary assembly cell—from small parts welding to filter assembly to pump assembly—can benefit from a precision indexing table. If you are currently using a manual turntable or a simple pneumatic indexer with poor repeatability, our tables will reduce defects and improve cycle time.

Why Choose SJ Petroleum Machinery?

Backed by a Global Industrial Powerhouse

SJ Petroleum Machinery is a wholly-owned subsidiary of Sinopec Oilfield Equipment Corporation—a company with over 50 years of experience manufacturing heavy-duty rotating equipment. That same engineering rigor goes into every assembly line indexing table we build. But unlike automation specialists who focus only on light-duty tables, we understand high-load, high-cycle applications.

Built for Production, Not Prototypes

We do not make hobby-grade indexers. Our smallest table supports 100 kg axial load. Our largest supports 50 tons. Every table is designed for 10+ years of continuous operation, with oversized bearings, case-hardened cams, and sealing that keeps contaminants out. If your line runs 24/7, you need a table built by people who understand reliability.

True Customization – Not Just "Options”

Standard tables come with fixed station counts and through-hole sizes. But assembly lines are never truly standard. We offer:

Custom number of stations (any integer from 2 to 99)
Non-standard table diameters
Special mounting bolt patterns
Custom center heights
Integration with your existing fixtures
OEM branding (your logo, your color)

Our engineering team works directly with your machine builder or in-house automation group.

Global Parts & Support

We stock wear parts (cam rollers, bearings, seals, motors) in our Jingzhou factory, Houston warehouse, and Dubai hub. Air freight delivery within 3–5 days to most industrial regions. Our technicians provide remote video support for troubleshooting and can travel on-site for commissioning or major repairs.

Cost-Effective Without Cutting Corners

Compared to European or Japanese brands, our pricing is typically 30–50% lower for equivalent specifications. We achieve this through efficient manufacturing, not by compromising on materials or testing. Every table undergoes 2-hour run-in, accuracy verification, and load testing before shipping.

Third-Party Certifications Available

We welcome SGS, BV, or TÜV inspections. Full material certificates, hardness test reports, and dimensional inspection records are provided with every shipment.

Frequently Asked Questions (FAQ)

Q1: What is the typical index time for a 12-station table?

For a roller cam table with 12 stations, a 600 mm diameter, and a 100 kg load, index time is typically 0.8–1.2 seconds. The exact time depends on inertia, motor size, and acceleration settings. We provide cycle time calculations before you buy.

Q2: Can I change the number of stations after the table is built?

On mechanical fixed-station tables (with physical detents), no – the number of stations is determined by the cam curve. On programmable tables (servo-driven with electronic indexing), you can change station count via software at any time. Tell us which flexibility you need.

Q3: How do I integrate the table with my existing PLC?

We provide wiring diagrams, sample ladder logic, and configuration files for major PLC brands. For Siemens, we can provide a TIA Portal function block. For Allen-Bradley, an Add-On Instruction. We also support direct I/O control (start index, done output, fault output) for simpler systems.

Q4: What maintenance does the table require?

Grease cam rollers and bearings every 2,000 operating hours (centralized fitting provided)
Inspect seals and fasteners every 5,000 hours
Replace cam roller bearings every 20,000–30,000 hours (depending on load)
That’s it. No daily adjustments.

Q5: Can the table be used in a cleanroom environment?

Yes – we offer tables with:

Sealed bearings (no exposed grease)
Smooth stainless steel or electropolished surfaces
HEPA-compatible seals
Class 100 (ISO 5) cleanroom compatibility
Specify your cleanroom class when requesting a quote.

Q6: What is the maximum part weight per station?

That depends on table size and station count. For a 600 mm roller cam table with 12 stations, maximum part weight per fixture is typically 15–20 kg when distributed evenly. For heavy parts (engine blocks, 50+ kg), we recommend a larger worm gear table with fewer stations. Send us your load and fixture layout – we will calculate.

Q7: Do you offer rotary tables with integrated slip rings or rotary unions?

Yes. For through-hole tables, we can pre-mount slip rings (for electrical signals) and rotary unions (for air or coolant). We work with trusted suppliers like Moog, Deublin, or Mercotac. Provide your specification (number of circuits, pressure, etc.) and we will integrate.

Q8: What is your warranty?

18 months from shipment or 12 months from commissioning, whichever occurs first. Warranty covers defects in materials and workmanship. Wear parts (cam rollers, bearings, seals) are covered for 12 months. We keep spare parts in stock to minimize downtime.

Q9: Can I see a table in operation before buying?

Yes. We have demo units at our Jingzhou factory and can arrange a live video demonstration showing indexing speed, repeatability measurement, and integration with a PLC. For serious buyers, we can ship a demo table for 30-day trial (terms apply).
