Sprocket DIagram

Outside Diameter: The diameter of a sprocket at it's external circumference

Pitch Diameter: The diameter through which the chain pin centers move around the sprocket. This is the area of the tooth that bears most of the load.

Root Diameter: Denotes the diameter of the sprocket at the root of the tooth. Tooth height is calculated by comparing the outside diameter with the root diameter. Used only with even tooth count.

Caliper Diameter: Denotes the diameter of the sprocket at the valley between two teeth. This measurement is used when the sprocket has an odd number of teeth.

Bore Diameter: This is the diameter of the mounting shaft. The sprocket will be bored to suit the shaft diameter.

Sprocket Width: Measures the thickness of the sprocket. When measuring sprockets with multiple tooth sets (double, triple, double-single etc.), measure the total width across all teeth. Face width is restricted by load requirements: too thin and the sprocket won't be able to sustain sufficient working load.

Hub Outside Diameter: Measures the diameter across the outside of the hub. Minimum hub thickness is determined by required bore size and load requirements.

Length Through Bore: The total length of the bore, through both the hub and face. The minimum LTB is determined by the required chain load: a sprocket with a bigger LTB will be more stable and have a higher load capacity.

A-Hub
Quick Disconnect

Tapered bushing is inserted into QD hub and is bolted onto the sprocket, providing a friction fit.

A-Hub
Taper Lock

Tapered bushing insert creates a tight friction fit when screws are inserted.

A-Hub
BKS (Bore, Key, Set Screws)

Sprocket is affixed with keyway and set screws. Simple, ideal for light work applications.

A-Hub
Split Taper

Split taper provides a tight hold on the drive shaft when compressed.

A-Hub
Split Through Bolt

Split hub with through bolts. Generally nuts and washers are parts of the provided hardware package.

A-Hub
Split Bolt

Split hub with socket head bolts. Hubs are pre-threaded to receive bolts during manufacturing.

A-Hub
Locking Element

Friction fit insert with hex bolts. Opposing wedges are drawn together by the bolts to provide a secure grip.

A-Hub
Pilot Bore

Pilot hole drilled through the center

A-Hub
A-Hub Sprocket

Also known as "A-plate" sprockets. No hub on either side of the plate.

B-Hub
B-Hub Sprocket

Hub extends on one side only.

C-Hub
C-Hub Sprocket

Hub extends from both sides of the plate.

C-Hub
Duplex Sprocket

Operates with a double strand chain. The strands of chain are connected, with a pin that runs through both sets of barrels.

C-Hub
Dual Sprocket

Designed to run two single strands of chain simultaneously. The two strands are not connected.

C-Hub
Triplex Sprocket

Operates with a triple strand chain. The strands of chain are connected, with a pin that runs through all three sets of barrels.
