Behind the part amount a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket can be a QD or taper bushed style the guts letter for the hub designation is definitely changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the part quantity if the sprocket is produced from a particular material. This designation can be placed in the front of the part quantity 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 – Since the bottom diameter (BD) of a sprocket with odd number of teeth can’t be measured directly, caliper diameters will be the measurement over the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle followed by the centers of the chain pins as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside Diameter (OD) The exterior diameter may be the measurement from the end of the sprocket tooth across to the corresponding point directly over the sprocket. It really is comparatively unimportant as the tooth duration is not vital to proper meshing to with the chain. The exterior diameter may vary depending on the kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance across the hub in one side to another. This diameter must not exceed the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper power. The dimensional allowance should be made for keyway and arranged screws.
Face Width (T) – Encounter width is limited in its optimum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimal width is limited to provide the proper strength to carry the imposed loads.
Duration Thru Bore (L) – The space thru bore must be sufficient to allow an extended enough key to withstand the torque transmitted by the shaft. This also actions the balance of the sprocket on the shaft.
ANSI-CERTIFIED ROLLER CHAIN SPROCKETS
Industrial chain sprocket breakages may bring your machinery to a grinding halt. Many devices can’t operate without their drive teach sprockets, and replacing them can cost lots of time and cash. Additionally, the functionality of a conveyor or drive depends on sprocket-chain conversation. Using the proper sprocket is simply as important as choosing the right chain.

If at any point you have queries or difficulty finding or choosing your sprocket please get in touch with our customer service department and we’ll be happy to help you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are created to run two single-strand type roller chains, this is where the name “dual single” originated from. Typically these sprockets are A design but both BTB taper bushed and QD design is available from stock. Our double one sprockets are produced with hardened the teeth and have a dark oxide coating for excellent performance and hook corrosion resistance. Stock sizes of double solitary sprockets range from ANSI #40 – #160 but additional sizes can be manufactured upon request. We can also supply quick response custom re-bores and MTO specialized double single sprockets due to our quick response in-house machine shop. Something important to note is that even though these sprockets are dual sprockets they’ll not double-strand roller chain. The charts below display the in-stock double solitary sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “conditions” or nomenclature to spell it out their sprockets. Though, throughout the general history of roller chain sprockets nearly every produce utilizes four different types of sprockets and has followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also known as A-Plate or just “plate sprocket” is 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 using one side.
Style C, also referred to as C-Hub sprockets can be a sprocket with a hub that extrudes on both sides.
Style D, is a sprocket with a detachable bolt-on hub mounted on a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets begins with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles as well as several other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are created to operate two single-strands of roller chain side parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also referred to as “quick detachable” utilize a tapered bushing that is bolted into the bore that’s machined in the sprocket. When the bushing can be inserted in to the sprocket can be compresses onto the shaft, which gives a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another design of interchangeable bushed sprockets that delivers a positive grasp on the driven shaft.
Shear Pin sprockets use a shear pin type hub that’s bolted to a sprocket to supply an overload gadget. If the torque ranking is certainly exceeded the shear gadget 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 part number, standardly the chain pitch will be created first, then your hub style or code, and accompanied by the number of the teeth the sprocket has. If the sprocket is certainly multi strand there will most often be considered a letter prefix at the start of the part quantity.
