Behind the part amount a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is usually a QD or taper bushed style the guts letter for the hub designation is usually changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the part number if the sprocket is manufactured from a particular material. This designation could be placed in the front of the part number or behind, if it’s noted.
Bottom Diameter (BD) – This is 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 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 since the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside Diameter (OD) The exterior diameter is the measurement from the tip of the sprocket tooth across to the corresponding stage 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 depending on the type of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance over the hub from one side to some other. This diameter must not exceed the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper power. The dimensional allowance must be made for keyway and set screws.
Face Width (T) – Encounter width is limited in its maximum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimum width is limited to provide the proper strength to transport the imposed loads.
Size Thru Bore (L) – The distance 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 devices can’t operate without their drive train sprockets, and replacing them can cost a lot of time and cash. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain interaction. Using the proper sprocket is simply as important as selecting the most appropriate chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are designed to execute well under pressure and so are long lasting.

Our standard single strand roller chain sprockets are produced with hardened tooth (for tooth counts under 30), used high quality quality SAE 1045 metal 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. Following 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 queries or trouble finding or selecting your sprocket please get in touch with our customer service department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one 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 style is available from share. Our double single sprockets are produced with hardened teeth and have a dark oxide coating for superior performance and a slight 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 store. Something important to note is that despite the fact that these sprockets are dual sprockets they will not double-strand roller chain. The charts below display the in-stock double one sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “terms” 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 referred to as A-Plate or simply “plate sprocket” is a set sprocket plate-wheel without hubs that extrude on either side.
Style B, also called B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also known as C-Hub sprockets is usually 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 begins with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles as well as many other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are made to operate two single-strands of roller chain side parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also called “quick detachable” make use of a tapered bushing that is bolted into the bore that is machined in the sprocket. When the bushing is usually inserted in to the sprocket can be 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 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 component amount, standardly the chain pitch will be written first, then your hub design or code, and followed by the number of the teeth the sprocket has. If the sprocket is certainly multi strand there will frequently be a letter prefix at the start of the part quantity.
