Behind the part amount a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is usually a QD or taper bushed design the guts letter for the hub designation is definitely changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the component quantity if the sprocket is manufactured from a special material. This designation can be placed in the front of the part number or behind, if it is noted.
Bottom Diameter (BD) – This is the measurement of the diameter of a circle tangent to the bottoms of the tooth areas.
Caliper Diameter – Since the bottom diameter (BD) of a sprocket with odd quantity of teeth cannot be measured directly, caliper diameters are the measurement across the tooth spaces almost 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 outside 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 size is not vital to proper meshing to with the chain. The outside diameter may vary based on the kind of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance across the hub in one side to another. This diameter must not go beyond the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper power. The dimensional allowance must be designed for keyway and established screws.
Face Width (T) – Face width is bound in its maximum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimal width is bound to provide the proper strength to transport the imposed loads.
Length Thru Bore (L) – The distance thru bore must be sufficient to allow an extended enough essential to withstand the torque transmitted by the shaft. This also measures 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 their drive teach sprockets, and changing them can cost considerable time and cash. Additionally, the overall performance of a conveyor or drive depends on sprocket-chain conversation. Using the right sprocket is simply as important as choosing the right chain.

SINGLE STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We share a complete type of each type! Our regular one strand roller chain sprockets are manufactured with hardened the teeth (for tooth counts under 30), used premium quality SAE 1045 steel material, and are finished with black-oxide for corrosion level of resistance.
To start out shopping simply choose what chain size you are using with your sprocket. Next select the type needed, finally select the preferred tooth count and possible accessories needed, then you are ready to obtain your sprockets! If at any point you have queries or problems finding or picking your sprocket please get in touch with our customer service department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are created to operate two single-strand type roller chains, that’s where the name “double single” originated from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from stock. Our double one sprockets are manufactured with hardened the teeth and have a dark oxide coating for superior performance and hook corrosion resistance. Share sizes of double single sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon request. We can also supply quick response custom re-bores and MTO specialty double single sprockets due to our quick response in-house machine shop. Something vital that you note is that despite the fact that these sprockets are double sprockets they’ll not double-strand roller chain. The charts below show the in-stock dual one sprocket sizes and have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to describe their sprockets. Though, throughout the general background of roller chain sprockets almost every produce utilizes four different types of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called 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 
Style C, also called C-Hub sprockets is definitely 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 previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles as well as several other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are created to run two single-strands of roller chain aspect parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” use a tapered bushing that is bolted into 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 provides 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 grip on the driven shaft.
Shear Pin sprockets use a shear pin type hub that’s bolted to a sprocket to provide an overload device. If the torque rating is certainly exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation with out disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component quantity, standardly the chain pitch will be created first, then the hub design or code, and followed by the number of tooth the sprocket has. If the sprocket is multi strand there will most often be a letter prefix at the start of the part number.
