Açıklama
Hollow pin roller chains are a direct pin-bore variant of standard ANSI/ISO roller chains. Every connecting pin is drilled through its full length, creating a hollow bore that allows cross rods, clevis bolts, pusher blades, bucket ears, and gripper pins to pass completely through the chain. The attachment is rigid, aligned to chain pitch, and requires no welding or secondary machining to the link plates — preserving the full fatigue strength of the chain. Because pitch, roller diameter, and plate dimensions conform to ANSI B29.1 and ISO 606, hollow pin chains run on standard sprockets without tooling changes: a 60HP chain engages the same 19.05 mm-pitch sprocket as a conventional #60 roller chain.
roller-chain-manufacturers.com supplies hollow pin chains in single-pitch (40HP–160HP) and double-pitch (C2040HP–C2080HP) series, in carbon steel, 304 stainless, and 316 stainless, with optional electropolish for food-grade and hygienic-zone installations. Custom pin bore diameters and extended-pin versions are available on request with a 7–15 working-day lead time.

Tensile strength = minimum breaking load (MBL). Design working load = MBL ÷ 7. Pin bore tolerance ±0.05 mm. Custom bore diameters and extended pins on request.
Key Design Features
⬡
Through-Bore Pin
Full-length hollow bore through every connecting pin. Accepts cross rods, clevis bolts, pusher blades, or bucket ears — no welding, no secondary machining required.
⚙
Runs Standard Sprockets
Pitch, roller diameter, and plate dimensions conform to ANSI B29.1 / ISO 606. Swap directly onto existing conveyor drives — no sprocket change, no re-engineering.
🔩
Three Material Grades
Carbon steel (zinc-plated) for general duty; SS304 for food-grade and light washdown; SS316 for marine, chemical, and heavy CIP cleaning cycles.
⬛
Single & Double Pitch
Double-pitch C2xxx HP series reduces link count by 50 %, cutting chain weight ~30 % on long slow-speed conveyors such as chip pans, oven transfers, and drying tunnels.
💪
Shot-Peened Plates
Link plates are shot-peened after blanking and heat treatment, improving fatigue life by up to 20 % on high-cycle conveyor applications compared to non-peened plates.
🔗
Unlimited Attachments
Any standard M-series attachment bar, angle bracket, side-plate lug, or custom fabrication can be locked to the hollow pin with a split pin or circlip — field-configurable without chain disassembly.
Typical Applications
Material & Finish Options
| Seviye | Components | Yüzey İşlemi | Best For |
|---|---|---|---|
| STD | Carbon steel — S45C pins & bushings, hardened plates | Zinc-plated plates, oiled for rust prevention | General industrial — dry or lightly lubricated indoor use |
| SS304 | Stainless steel 304 — all components | Passivated; electropolish available on request | Food processing, dairy, light washdown, pharmaceutical |
| SS316 | Stainless steel 316L — all components | Passivated | Marine, chemical exposure, heavy CIP cleaning cycles |
Sprocket Compatibility
Hollow pin chains share the same pitch, roller diameter, and plate thickness as standard ANSI / ISO makaralı zincirler — they engage existing sprockets without modification. A 60HP chain uses the same 19.05 mm-pitch, 11.91 mm-roller sprocket as a conventional #60 chain. Plant engineers can trial hollow-pin chains on live conveyor drives before full redesign commitment. Matching carbon-steel and stainless-steel sprockets — 9T to 120T, bored to shaft — are available as companion products from roller-chain-manufacturers.com.
