Behind the part quantity a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is certainly a QD or taper bushed design the guts letter for the hub designation is usually changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the part amount if the sprocket is manufactured from a special material. This designation could be placed in the front of the part number 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 level diameter (BD) of a sprocket with odd quantity of teeth can’t 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 may be 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 may be the measurement from the tip of the sprocket tooth across to the corresponding point directly over the sprocket. It really is comparatively unimportant as the tooth size is not essential to appropriate 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 over the hub in one side to some other. This diameter must not surpass the calculated diameter of the within of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall structure thickness for proper strength. The dimensional allowance must be made for keyway and set screws.
Face Width (T) – Face width is limited in its optimum dimension to permit proper clearance to provide for chain engagement and disengagement. The minimal width is bound to provide the correct strength to carry the imposed loads.
Length Thru Bore (L) – The length thru bore must be sufficient to allow an extended enough essential 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 a lot of 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 choosing the right chain. At Ever-power Roller Chain, we provide a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are engineered to execute well under pressure and are resilient.

Our regular one strand roller chain sprockets are manufactured with hardened tooth (for tooth counts under 30), used high quality quality SAE 1045 metal material, and are completed with black-oxide for corrosion resistance.
To start shopping simply select what chain size you are employing with your sprocket. Next select the type needed, lastly select the preferred tooth count and feasible accessories needed, then you are ready to obtain your sprockets! If at any point you have questions or difficulty finding or selecting your sprocket please contact our customer support department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are made to run two single-strand type roller chains, that’s where the name “double single” came from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from share. Our double one sprockets are produced with hardened the teeth and have a black oxide coating for excellent performance and a slight corrosion resistance. Share sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon demand. We are able to also supply quick response custom re-bores and MTO specialized double single sprockets due to our quick reaction in-house machine shop. Something vital that you note is that despite the fact that these sprockets are dual sprockets they will not double-strand roller chain. The charts below show 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 describe their sprockets. Though, throughout the general background of roller chain sprockets nearly every produce utilizes four various kinds of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or simply “plate sprocket” can be a set sprocket plate-wheel with no hubs that extrude on either side.
Style B, also referred to as B-Hub sprockets is a sprocket with a hub that extrudes using 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 mounted on a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets will start with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles and also many other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are created to operate two single-strands of roller chain part parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” utilize a tapered bushing that’s bolted into the bore that’s machined in the sprocket. When the bushing is usually inserted in to the sprocket is certainly compresses onto the shaft, which gives 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 make use of a shear pin type hub that is bolted to a sprocket to supply an overload device. If the torque rating is exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation with no disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part number, standardly the chain pitch will be written first, then your hub style or code, and followed by the number of teeth the sprocket has. If the sprocket is certainly multi strand there will most often be a letter prefix at the start of the part quantity.
