Behind the part amount a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is definitely a QD or taper bushed style the guts letter for the hub designation is changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the component amount if the sprocket is produced from a special material. This designation could be placed in the front of the part amount 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 amount of teeth cannot be measured directly, caliper diameters will be the measurement over 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 as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The exterior diameter is the measurement from the end of the sprocket tooth across to the corresponding stage directly over the sprocket. It is comparatively unimportant as the tooth duration is not essential to correct meshing to with the chain. The outside diameter may vary based on the type of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance across the hub from one side to some other. 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 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 optimum dimension to allow proper clearance to supply 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 distance thru bore should be sufficient to allow a long 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 machines can’t operate without their drive teach sprockets, and replacing them can cost considerable time and cash. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain interaction. Using the right sprocket is simply as important as choosing the right chain. At Ever-power Roller Chain, we offer a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are manufactured to perform well under pressure and so are resilient. The roller chain sprockets for sale in our shop include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets.

Our standard one strand roller chain sprockets are produced with hardened tooth (for tooth counts under 30), used premium quality SAE 1045 metal material, and are completed with black-oxide for corrosion level of resistance.
To start out shopping simply select what chain size you are using with your sprocket. Next select the type needed, lastly select the preferred tooth count and possible accessories needed, then you are ready to obtain your sprockets! If at any point you have questions or problems finding or selecting your sprocket please contact our customer service department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are made to run two single-strand type roller chains, this is where the name “dual single” came from. Typically these sprockets are A design but both BTB taper bushed and QD design is available from stock. Our double solitary sprockets are produced with hardened the teeth and have a black oxide coating for excellent performance and hook corrosion resistance. Stock sizes of double one sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon request. We are able to also supply quick reaction custom re-bores and MTO specialty double single sprockets because of our quick response 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 display the in-stock dual single 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 describe their sprockets. Though, throughout the general background of roller chain sprockets nearly every produce utilizes four various kinds 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 definitely a flat sprocket plate-wheel with no hubs that extrude on either side.
Style B, also called B-Hub sprockets is a sprocket with a hub that extrudes on one side.
Style C, also called C-Hub sprockets is definitely 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 standard styles along with several 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 One (these sprockets are created to 
COMMON SPROCKET STYLES
QD style sprockets, also referred to as “quick detachable” make use of a tapered bushing that’s bolted in to the bore that is machined in the sprocket. When the bushing is usually inserted in to the sprocket is certainly compresses onto the shaft, which provides a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another design of interchangeable bushed sprockets that provides 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 rating is usually exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation without disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component number, standardly the chain pitch will be written first, then the hub style or code, and accompanied 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.
