SKF Sprocket, 20 Teeth, 50mm Sprocket Width - PHS 12B-2BH20

This sprocket is a steel drive wheel designed to transmit rotary motion via a compatible roller chain in industrial assemblies. It is supplied with a rough stock bore to allow final machining to match a shaft, and meets recognised EN and BS standards for dimensioning and material conformity.

Features and Benefits:

• Steel construction provides high wear resistance and longevity
• Twenty teeth enable precise engagement with chain links
• Compatible with 12B-2 chain for reliable power transmission
• Fifty mm width supports lateral load distribution
• Maximum inside diameter 64 mm permits clearance for hub machining

Applications

• Suitable for conveyor drive systems in factories
• Used with agricultural machinery requiring chain drive
• Ideal for retrofitting worn chain sprockets in plants
• Can be used for power transmission in material handling
• Used for bespoke drive assemblies needing bore finishing

What bore preparation is required before assembly?

The rough stock bore requires finishing to the final shaft diameter and keyway cutting to ensure correct fit and torque transmission.

What should be considered when matching chain type?

Select 12B-2 chain matching the sprocket tooth profile and pitch diameter to maintain proper engagement and minimise wear.

How does hub diameter affect installation?

The 100 mm hub diameter determines mounting envelope and provides material for machining features such as setscrew bores or taper fits.

Which metric determines the sprocket’s rolling contact with the chain?

The pitch diameter of 121.78 mm governs the centre distance and sprocket-to-sprocket spacing for correct chain geometry.
