Engineering Knowledge
Anatomy of a Roller Chain
Every roller chain component is engineered to specific material and tolerance specifications. Understanding the anatomy helps select the correct chain series and predict service life.
01
Inner Link Plate
Transmits tensile load between pins. Cold-rolled steel with controlled hole tolerances to prevent fatigue cracks at stress concentration points.
Medium carbon steel · HRC 38–4502
Outer Link Plate
Press-fit to connecting pins to form the rigid outer link assembly. Same material and heat treatment as inner plates.
Carbon steel · Black oxide03
Connecting Pin
Hardened cylinder joining outer plates through inner bushings. Surface hardness controls the pin–bushing wear rate directly.
Case-hardened · 55–60 HRC surface04
Roller Bushing
Hollow cylinder pressed into inner plates. The pin articulates inside — the highest-wear surface in the entire chain system.
Sintered steel · Oil-impregnated bore05
Free Roller
Rotates freely on the bushing, engaging the sprocket tooth root with rolling contact — the key efficiency advantage of roller chain.
Case-hardened · 55–62 HRC

Selection Tool
How to Choose the Right Chain
The wrong chain specification is the most common cause of premature drive failure. Follow these four steps to define your correct specification before ordering.
1
Define Power & Speed
Determine design power (kW/HP) and small sprocket RPM. Apply service factor: uniform load ×1.0, moderate shock ×1.3, heavy shock ×1.7.
Uniform LoadModerate ShockHeavy Shock
2
Select Chain Pitch
Smaller pitch = smoother at high speed. Larger pitch = higher load at lower speed. Use ANSI selection charts for corrected design power.
#35 (3/8")#40 (1/2")#60 (3/4")#80 (1")
3
Choose Sprocket Configuration
B-Hub standard drives, Taper Lock variable shaft, QD for rapid replacement, Split for inaccessible shaft positions.
B-HubTaper LockQD BushedSplit
4
Specify Material & Environment
Carbon steel for dry indoor use. Stainless 316 for washdown/chemical. UHMW plastic for food zones requiring zero metal contamination.

Customer Feedback
Trusted by Korean Industry Leaders
★★★★★
We replaced our entire combine chain set with Korea Ever-Power #60 ANSI chain and CA550 sprockets. Their series confirmation service caught a spec error that would have sent wrong parts — saving a 3-week delay during harvest season.

Equipment Manager · Jeonbuk Agricultural Cooperative
★★★★★
Two years ordering 94- and 95-series engineer class sprockets. The pre-order series identification — confirming roller diameter before machining — has prevented cross-series errors that plagued us with previous suppliers.
