Application of 16A-3-16T Type A Triple Row Sprocket

 

The 16A-3-16T Type A triple row sprocket is an ISO-standard hubless transmission part, specially designed to match 16A series triple-row roller chains. Benefiting from its triple-row structure, it features far stronger load-bearing capacity and torque resistance than single-row and double-row sprockets, which makes it prioritized for heavy-load industrial transmission scenarios.

As a hubless Type A sprocket, it fits equipment with reserved mounting hubs, saving installation space and simplifying mechanical assembly. It is widely adopted in heavy-duty conveying machinery, large-scale automated production lines and metallurgical transmission equipment. Besides, it works perfectly for stone processing machines, heavy agricultural machinery and mining material handling devices that require stable high-torque power output.

It also applies to large logistics sorting equipment and industrial lifting machinery running under long-duration continuous working conditions. Thanks to high machining accuracy, it maintains stable meshing operation even under heavy pressure, lowering mechanical failure rates. With standardized overall dimensions and strong part interchangeability, it can directly replace old sprockets without mechanical modification. It is a durable, low-maintenance and cost-effective drive component for harsh industrial working environments.

 

FAQ for 16A-3-16T Type A Triple Row Sprocket

Q1: What does the model stand for? 16A follows ANSI standard with 25.4mm pitch. 3 means triple row, 16T is 16 teeth, and Type A is flat plate design without hub.

Q2: Compatible chain & usage? It matches ANSI 16A-3 triple row roller chain. Ideal for heavy-load industrial transmission, conveyors and processing equipment.

Q3: Service notes? Made of durable carbon steel with heat-treated teeth. Keep proper lubrication and aligned shafts to reduce wear and noise. Custom bore is also available.
