Steel Straight Run Flat-Top Chains — Standard and Derived Series

---

Product Overview

CARPARTNER supplies steel straight run flat-top chains for conveyor systems requiring a stable flat conveying surface and straight-line chain travel. The supplied catalog page presents two product families:

• Standard series: C12S, C13S, C14S, C16S, C18S, C20S, C24S, C30S and double-hinge C30D.
• Derived series: 25.4-CS54 through 25.4-CS98, 36-CS80, 36-CS90, 38.1-CS53 and 38.1-CS62.

The source drawings show the chain plate layout and roller/pin side views with labels b1, b2, d1, d2, T and P. The Standard series table identifies single-hinge and double-hinge constructions; the Derived series table lists DIN/ISO-style chain numbers with application-specific b2 widths.

Key Features

• Straight-running flat-top construction: Suitable for direct conveyor runs and stable product support where the conveyor layout does not require side-flexing articulation.
• Standard and derived options: C12S–C30S, C30D and multiple CS-derived chain numbers are listed in the supplied tables.
• Single-hinge and double-hinge configurations: C30D is identified as a double-hinge chain in the Standard series table.
• Smooth conveying surface: The flat-top plate arrangement provides a broad contact surface for supported products, subject to the selected chain and conveyor design.
• Common Standard pitch: The Standard series table shows P = 38.1 mm.
• Derived pitch choices: The Derived series includes 25.4 mm, 36.0 mm and 38.1 mm pitch groups.
• Detailed dimensional reference: Tables include b2, b1, d2, T, d1(max), steel-category U.T.S./A.T.S. fields and q in kg/m.
• Replacement and OEM-style support: CARPARTNER can review original chain samples, machine drawings, DIN/ISO numbers and conveyor measurements.

Technical Drawing Reference

The corrected technical drawing retains two source groups:

• Left single-hinge group: top/plate arrangement and side view with b1, b2, d2, d1, T and P labels.
• Right double-hinge group: top/plate arrangement and side view with the same source-visible labels.

The drawing is intended for configuration identification. Do not infer unlisted numerical values from the illustration alone.

Technical Parameters — Standard Series

All dimensional values are in mm unless otherwise stated. Strength fields are shown in kN, and q in kg/m, matching the source table.

Technical Parameters — Derived Series

The Derived series preserves the catalog’s DIN/ISO-style chain-number notation and the visible b1 grouping. All dimensional values are in mm; strength fields are kN and q is kg/m.

Standard and Derived Series Selection

Standard Series

Select the Standard series when the conveyor design matches the C12S–C30S or C30D naming and the 38.1 mm pitch family shown in the source table. C30D is identified as a double-hinge configuration and should not be substituted for a single-hinge chain without confirming the conveyor and sprocket arrangement.

Derived Series

Select the Derived series when the original machine documentation or sample uses the 25.4-CS, 36-CS or 38.1-CS naming. The b2 dimension varies by chain number, while the visible b1 arrangement includes 42.0 mm for the first 25.4-CS row, 40.5 mm for 25.4-CS63 and a grouped 42 mm value for the remaining visible configurations.

Typical Applications

Public straight-running flat-top-chain references describe applications in conveying lines where products travel along a direct path. Common application contexts include:

• Bottles, cans and packaged-product conveying
• Food and beverage processing and packaging
• Pharmaceutical and general manufacturing lines
• Assembly and inspection conveyors
• Accumulation and transfer sections designed for straight travel
• Replacement of worn steel tabletop-chain assemblies

The source image does not identify one exclusive industry or machine. Actual suitability depends on the conveyed product, conveyor layout, load, speed, cleaning conditions, temperature, sprocket and wear-strip system.

Selection Guide

Please send the following details for accurate chain identification and quotation:

1. Conveyor manufacturer and machine model
2. Standard or Derived series
3. Original chain number, such as C16S, C30D, 25.4-CS82 or 38.1-CS62
4. Pitch P, chain width b2 and inner width b1
5. Pin/roller dimensions d1 and d2, and plate thickness T
6. Single-hinge or double-hinge construction
7. Sprocket tooth count, bore, shaft arrangement and wear-strip details
8. Required chain length, strand quantity and link count
9. Conveyed product type, dimensions, weight and contact surface
10. Operating speed, direction and approximate working load
11. Moisture, washdown, chemicals, dust and temperature exposure
12. Photos of the original chain, sprocket and conveyor nameplate

Do not select a replacement only by chain name or pitch. Chain width, hinge construction, sprocket fit, wear-strip clearance and total length must be checked together.
