Behind the part amount 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 style the center letter for the hub designation is changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the part quantity if the sprocket is produced from a particular material. This designation could 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 areas.
Caliper Diameter – Since the bottom diameter (BD) of a sprocket with odd quantity of teeth can’t 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 may be the circle accompanied by the centers of the chain pins because the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside Diameter (OD) The outside diameter is the measurement from the tip of the sprocket tooth across to the corresponding point directly across the sprocket. It is comparatively unimportant as the tooth size is not vital to proper meshing to with the chain. The outside diameter may vary depending on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance across the hub in one side to some other. This diameter must not exceed the calculated diameter of the within of the chain sidebars.
Maximum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper power. The dimensional allowance must be made for keyway and set screws.
Face Width (T) – Face width is bound in its optimum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimal width is bound to provide the proper strength to carry the imposed loads.
Size Thru Bore (L) – The space thru bore must be sufficient to allow a long enough crucial to withstand the torque transmitted by the shaft. This also steps 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 changing them can cost a lot of time and money. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain conversation. Using the right sprocket is just as important as choosing the right chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are designed to execute well under pressure and are long lasting.

Solitary STRAND ROLLER CHAIN 
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 produced with hardened tooth (for tooth counts under 30), used high quality quality SAE 1045 steel material, and are completed with black-oxide for corrosion resistance.
To start shopping simply choose what chain size you are using with your sprocket. Following select 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 queries or trouble finding or selecting your sprocket please contact our customer service department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are created to run two single-strand type roller chains, this is where the name “double single” originated from. Typically these sprockets are A style but both BTB taper bushed and QD style is available from share. Our double single sprockets are manufactured with hardened teeth and have a black oxide coating for excellent performance and hook corrosion resistance. Share sizes of double one sprockets range between 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 due to our quick response in-house machine store. 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 double one sprocket sizes and also have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “conditions” or nomenclature to describe their sprockets. Though, throughout the general background 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 called A-Plate or simply “plate sprocket” is certainly a set sprocket plate-wheel without 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 certainly a sprocket with a hub that extrudes on both sides.
Design 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 and also various other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are made to run two single-strands of roller chain part parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” use a tapered bushing that’s bolted into the bore that is machined in the sprocket. When the bushing can be inserted into the sprocket is 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 provides a positive grip on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that’s bolted to a sprocket to provide an overload gadget. If the torque ranking is certainly exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation without disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part quantity, standardly the chain pitch will be created first, then your hub style or code, and followed by the number of teeth the sprocket has. If the sprocket is definitely multi strand there will most often be a letter prefix at the beginning of the part quantity.
