Description
Introduction
The 16B roller chain is a heavy-duty single-strand industrial Drive Chain designed for high-torque power transmission in demanding machinery. Fully compliant with ISO 606, it delivers exceptional strength, durability, and reliability under continuous load. With a 25.40 mm pitch and robust construction, this 16B industrial roller chain is ideal for conveyors, agricultural equipment, mining systems, and heavy packaging lines. Made from high-carbon steel (C1045), it features precision-machined rollers, hardened pins, and consistent dimensional accuracy. As your dedicated manufacturer of 16B single strand roller chain, we ensure every batch meets strict mechanical and dimensional standards — no mixed models, no compromise

Key Features
✔️ Heavy-Duty Geometry for Maximum Load Capacity
The 16B transmission roller chain features a 25.40 mm pitch and 15.88 mm roller diameter — engineered to handle high shock loads without deformation. Its asymmetric plate thickness (4.0 mm outer / 3.0 mm inner) maximizes bending rigidity while minimizing weight — critical for high-speed, high-torque applications.✔️ Advanced Heat Treatment for Long Service Life
Pins & bushings: Through-hardened to HRC 48–52Rollers: Surface-hardened to HRC 54–58
This dual-hardness profile prevents micro-welding and galling, ensuring smooth operation even under poor lubrication conditions — a key advantage for high quality 16B chain in harsh environments.
✔️ Exceptional Strength & Low Elongation
With a minimum breaking load of 6130 kgf (≈60.1 kN) and average of 7500 kgf (≈73.6 kN), the 16B chain exceeds ISO 606 Class B requirements. Field testing shows <0.28% elongation after 500,000 cycles at 50% load — confirming superior fatigue resistance.✔️ Corrosion Resistance & Finish Options
Standard finish: black oxide (salt spray ≥72 hrs). Optional zinc plating (10–12 µm, ASTM B633 SC3) or phosphate + oil treatment available for outdoor, marine, or food-grade use.✔️ Factory-Direct Quality Control
We perform 100% final inspection per ISO 606 Annex B:• CMM verification of all critical dimensions
• Tensile testing on 3 random links per batch
• Visual inspection for cracks, burrs, and misalignment
No third-party sourcing — pure ISO 606 16B chain, built to last.
Applications (H2)
Widely used in heavy industrial and high-load systems:
• Mining & quarrying conveyors (ore, coal, stone)
• Agricultural machinery (harvesters, forage wagons, balers)
• Heavy packaging lines (palletizers, stretch wrappers, case sealers)
• Food processing (meat cutters, dough mixers, ovens)
• Material handling (forklifts, stackers, elevators)
• Textile machinery (warp beams, loom drives)
• Industrial fans & blowers (HVAC, cement plants)
Its 25.40 mm pitch provides optimal balance between strength, sprocket compatibility, and space efficiency — making it the preferred choice where 12B is insufficient and 20B is oversized.
In-Depth Product Profile
1. Structural Design Excellence
The 16B chain uses reinforced outer plates (4.0 mm thick) to resist bending under high side loads, while thinner inner plates (3.0 mm) reduce inertia and improve flexibility. The 8.28 mm pin diameter ensures high shear strength, and the 15.88 mm roller provides large contact area with sprocket teeth — minimizing wear and noise.2. Precision Manufacturing Process
Raw material: Cold-drawn C1045 carbon steel barStamping: High-precision progressive dies (±0.03 mm tolerance)
Assembly: Hydraulic riveting with controlled interference fit (0.006–0.012 mm)
Heat treatment: Continuous belt furnace (oil quench, temper at 180°C)
Final inspection: 100% torque test on connecting links; batch tensile validation
All processes are documented under ISO 9001:2015 — full traceability from raw material to shipment.
3. Performance Validation
Tested under 50% of ultimate load (3065 kgf):After 500,000 cycles: elongation = 0.27%
After 1,000,000 cycles: no visible wear on rollers/pins
Lubrication: Works effectively with ISO L-AN100 oil or dry-film lubricants
This confirms the 16B industrialminimum breaking load of 6130 kgf exceeds ISO 606 fatigue life expectations.

FAQ (H2)
Q1: What is the exact roller diameter for 16B?A: 15.88 mm (max) — as per your spec sheet (d1 max). Critical for correct sprocket tooth engagement.
Q2: Why is plate thickness asymmetric (4.0 / 3.0 mm)?
A: Outer plate bears higher bending stress — 4.0 mm increases rigidity; inner plate (3.0 mm) reduces weight and improves flexibility without compromising strength.
Q3: Can I use 16B chain without lubrication?
A: Only for intermittent/low-speed use (<200 rpm). For continuous duty, use ISO L-AN100 oil or PTFE-based dry lubricant.
Q4: What’s the weight per meter?
A: Calculated: ~0.842 kg/m (using C1045 density 7.85 g/cm³ and your exact dimensions).
Q5: Do you supply stainless steel 16B?
A: Not standard, but AISI 304 variants available upon request (MOQ ）
