SKF
Sprockets
SKF sprockets are precision-engineered toothed wheels that engage roller chains for positive, non-slip power transmission in conveyors, agricultural machinery, hoists, and industrial drives. The range includes roller chain sprockets in metric (ISO 606) and inch (ANSI) standards, with single, double, and triple strand configurations. They are manufactured from high-quality carbon steel, induction-hardened on tooth contact surfaces for wear resistance, or from stainless steel for corrosive environments. Sprockets are available with pilot bore, taper bushing, or finished bore with keyway and set screws. Common applications include bucket elevators, packaging conveyors, motorcycle final drives, and grain handling equipment. Using genuine SKF sprockets matched with SKF chains ensures precise tooth pitch and profile that minimises wear, noise, and vibration. Correct sprocket selection (number of teeth, pitch, hub style) directly influences chain life and drive efficiency.

Trusted by Industry Leaders
Induction-Hardened Teeth
Extended wear life under high chain tension.
ISO and ANSI Standards
Worldwide dimensional interchangeability.
Multiple Strand Capability
Single, double, triple sprockets for higher power transmission.
Taper Bush and Pilot Bore Options
Easy shaft mounting; one sprocket fits multiple shaft sizes with appropriate bushing.
Stainless Steel Options
Corrosion resistance for food, chemical, and marine applications.
Precise Tooth Profile
Minimises chain chordal action and noise.
Sprocket Tooth Count and Chain Life
Selecting a sprocket with too few teeth increases the chordal action (pulsation) and accelerates chain joint wear. SKF recommends minimum tooth counts (typically 17-19 teeth for standard drives) to extend chain life. For high-speed drives, larger sprockets with more teeth smooth the drive and reduce noise.
Taper Bush Sprockets for Conveyor Drives
In conveyor head and tail shafts, taper bush sprockets provide a tight, concentric grip on the shaft without the fretting corrosion common with keyed bores. Installation and removal are quick, using only an Allen key. This simplifies on-site replacement of worn sprockets and reduces downtime.
