SKF Sprocket, 12 Teeth, 42mm Bore Size - PHS 16B-1TBH12

This sprocket is a toothed drive wheel designed for roller chain power transmission in industrial settings. It fits 16B-1 chain and connects to shafts using a simplex taper bush, providing a Compact solution for transferring rotary motion in automation, electrical and mechanical systems.

Features and Benefits:

• Made from high-grade steel for Durable wear resistance
• Works with 16 B-1 chain for standard industrial compatibility
• Contains 12 teeth to match 12-tooth chain engagement requirements
• Utilises a simplex taper bush for secure, concentric mounting
• Conforms to BS and EN for recognised dimensional standards
• Hub diameter supports robust load distribution at mounting point

Applications

• Suitable for conveyor drives in automated assembly lines
• Ideal for chain-driven indexing mechanisms in electronics production
• Used with motor-reducer shafts in small mechanical drives
• Can be used as a replacement sprocket for 16B chain in maintenance tasks

What bore mounting option does it use for shaft attachment?

It employs a simplex taper bush arrangement that provides a tight interference fit on the shaft and allows easy removal by withdrawing the bush.

Which material characteristic affects service life under load?

The high-grade steel construction improves resistance to surface fatigue and abrasion under repeated chain engagement.

How does the hub diameter influence performance?

A 73mm hub diameter increases the contact area at the mounting interface, helping to distribute radial loads and reduce stress concentration.

What dimensional data determines chain engagement geometry?

The pitch diameter of 98.14mm controls the chain run radius and mesh geometry with mating sprockets.
