Behind the part number a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is definitely a QD or taper bushed design the center letter for the hub designation is definitely changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the part quantity if the sprocket is manufactured from a particular material. This designation could be placed in leading of the part number or behind, if it’s noted.
Bottom Diameter (BD) – This is actually the measurement of the diameter of a circle tangent to the bottoms of the tooth spaces.
Caliper Diameter – Because the bottom level diameter (BD) of a sprocket with odd quantity of teeth cannot be measured directly, caliper diameters are the measurement across the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle accompanied by the centers of the chain pins since the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The exterior diameter may be the measurement from the end of the sprocket tooth across to the corresponding point directly across the sprocket. It is comparatively unimportant as the tooth length is not essential to correct meshing to with the chain. The exterior diameter may vary depending on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance across the hub from one side to another. This diameter should never go beyond the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper power. The dimensional allowance should be made for keyway and established screws.
Face Width (T) – Face width is bound in its optimum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimum width is limited to provide the proper strength to carry the imposed loads.
Duration Thru Bore (L) – The length thru bore should be sufficient to allow an extended enough crucial to withstand the torque transmitted by the shaft. This also actions the stability of the sprocket on the shaft.
ANSI-CERTIFIED ROLLER CHAIN SPROCKETS
Industrial chain sprocket breakages can bring your machinery to a grinding halt. Many devices can’t operate without 
We’re positive you’ll be happy when you buy industrial chain sprockets in our shop, because they’ll last you a long time.

Our regular one strand roller chain sprockets are produced with hardened tooth (for tooth counts under 30), used superior quality SAE 1045 metal material, and are completed with black-oxide for corrosion resistance.
To start out shopping simply select what chain size you are employing with your sprocket. Next choose the type needed, lastly select the preferred tooth count and feasible accessories needed, you then are ready to obtain your sprockets! If at any stage you have questions or problems finding or selecting your sprocket please get in touch with our customer support department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are created to operate two single-strand type roller chains, that’s where the name “dual single” came from. Typically these sprockets are A style but both BTB taper bushed and QD design is available from share. Our double solitary sprockets are produced with hardened tooth and have a black oxide coating for superior performance and hook corrosion resistance. Share sizes of double solitary sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon ask for. We are able to also supply quick reaction custom re-bores and MTO specialized double single sprockets because of our quick reaction in-house machine shop. Something vital that you note is that even though these sprockets are dual sprockets they’ll not double-strand roller chain. The charts below show the in-stock dual one sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “terms” or nomenclature to spell it out their sprockets. Though, throughout the general history of roller chain sprockets nearly every manufacture utilizes four various kinds of sprockets and has adopted the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or just “plate sprocket” can be a set sprocket plate-wheel with no hubs that extrude upon either side.
Style B, also referred to as B-Hub sprockets is a sprocket with a hub that extrudes on one side.
Style C, also referred to as C-Hub sprockets is a sprocket with a hub that extrudes on both sides.
Style D, is a sprocket with a detachable bolt-on hub attached to a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets will start with a prefix except when previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles as well as various other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are made to operate two single-strands of roller chain side parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also called “quick detachable” make use of a tapered bushing that’s bolted in to the bore that’s machined in the sprocket. When the bushing is certainly inserted in to the sprocket is definitely compresses onto the shaft, which gives a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another style of interchangeable bushed sprockets that delivers a positive hold on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that’s bolted to a sprocket to supply an overload gadget. If the torque rating can be exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation with no disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component number, standardly the chain pitch will be created first, then your hub style or code, and followed by the number of the teeth the sprocket has. If the sprocket is certainly multi strand there will frequently be a letter prefix at the start of the part quantity.
