SKF Sprocket, 38 Teeth, 50.8mm Bore size - PHS 08B-1TB38


This sprocket is a steel drive component designed to transmit rotary motion within roller-conveyor and chain-driven assemblies. It interfaces with standard 08B-1 roller chain and uses a taper bush mounting system to secure the hub to a driven shaft, providing a straightforward replacement option for industrial material-handling and power-transmission equipment.

Features & Benefits


• Hardened-steel construction for wear resistance during continuous operation
• 38 teeth optimise engagement frequency for steady chain tracking
• Standards-compliant manufacture supports integration with regulated systems
• Broad hub diameter supports robust load transfer to driven shafts

Applications


• Suitable for conveyor drive trains in factory automation
• Ideal for chain-driven indexing tables in electronics assembly
• Used with industrial conveyors in electrical equipment production
• Can be used for replacement on 08B-1 chain conveyor systems
• Suitable for material handling conveyors requiring fixed-speed drives

What mounting method secures the sprocket to a shaft?


It uses a taper bush arrangement that clamps the hub onto the shaft when the bush is tightened, ensuring concentric alignment and straightforward removal.

Which chain form will engage properly with this part?


The tooth profile matches an 08B-1 roller chain, providing correct pitch engagement and reduced lateral play in the link joint.

How does the hub design affect torque transmission?


The sizeable hub diameter distributes radial load over a larger contact area, lowering bearing loads and improving torque transfer to the shaft interface.

What inspection points should be checked during preventive maintenance?


Monitor tooth profile wear, bush-to-shaft concentricity, and hub fastener torque to maintain smooth chain engagement and limit vibration.
