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 style the center letter for the hub designation can be changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the component number if the sprocket is produced from a special material. This designation could be placed in the front of the part number or behind, if it is noted.
Bottom Diameter (BD) – This is actually the measurement of the 
Caliper Diameter – Since the bottom diameter (BD) of a sprocket with odd quantity of teeth cannot be measured directly, caliper diameters are the measurement over the tooth spaces almost opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which may be the circle followed by the centers of the chain pins as 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 tip of the sprocket tooth across to the corresponding stage directly across the sprocket. It really is comparatively unimportant as the tooth length is not vital to correct meshing to with the chain. The exterior diameter may vary based 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 exceed the calculated diameter of the within of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper strength. The dimensional allowance must be made for keyway and arranged screws.
Face Width (T) – Face width is bound in its maximum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimal width is limited to provide the proper strength to carry the imposed loads.
Size Thru Bore (L) – The length thru bore must be sufficient to allow a long enough essential 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 can bring your machinery to a grinding halt. Many machines can’t operate without their drive teach sprockets, and replacing them can cost considerable time and money. Additionally, the efficiency of a conveyor or drive depends on sprocket-chain interaction. Using the right sprocket is simply as important as deciding on the best chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are manufactured to execute well under pressure and so are long lasting.

Solitary STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We stock a complete line of each type! Our standard solitary strand roller chain sprockets are produced with hardened tooth (for tooth counts under 30), used superior quality SAE 1045 steel material, and are finished with black-oxide for corrosion level of resistance.
To start shopping simply select what chain size you are employing with your sprocket. Next choose the type needed, finally select the preferred tooth count and possible accessories needed, you then are ready to get your sprockets! If at any point you have queries or trouble finding or picking your sprocket please get in touch with our customer service department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are created to run two single-strand type roller chains, that’s where the name “double single” originated from. Typically these sprockets certainly are a style but both BTB taper bushed and QD design is available from stock. Our double one sprockets are produced with hardened teeth and have a black oxide coating for excellent performance and a slight corrosion resistance. Share sizes of double single sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon request. We can also supply quick response custom re-bores and MTO specialty double single sprockets because of our quick reaction in-house machine shop. Something vital that you note is that despite the fact that 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 product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “conditions” or nomenclature to spell it out their sprockets. Though, through the entire general background of roller chain sprockets nearly every manufacture utilizes four various kinds of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also known as A-Plate or just “plate sprocket” can be a flat sprocket plate-wheel without hubs that extrude upon either side.
Style B, also known 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.
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 begins with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles in addition to various other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are created to operate two single-strands of roller chain aspect parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” make use of a tapered bushing that is bolted into the bore that is machined in the sprocket. When the bushing is definitely inserted in to 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 grasp on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that is bolted to a sprocket to provide an overload gadget. If the torque rating is definitely exceeded the shear gadget 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 component amount, standardly the chain pitch will be created first, then the hub design or code, and accompanied by the number of teeth the sprocket has. If the sprocket is usually multi strand there will frequently be considered a letter prefix at the beginning of the part amount.
