Behind the part quantity 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 design the guts letter for the hub designation is certainly changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the part quantity if the sprocket is manufactured from a special material. This designation could be placed in leading 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 spaces.
Caliper Diameter – Since the bottom level diameter (BD) of a sprocket with odd number of teeth can’t be measured directly, caliper diameters will be the measurement across the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle accompanied by the centers of the chain pins because 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 over the sprocket. It really is comparatively unimportant as the tooth length is not vital to appropriate 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) – Is the distance over the hub from one side to some other. This diameter must not surpass the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper strength. The dimensional allowance must be designed for keyway and established screws.
Face Width (T) – Face width is limited in its maximum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimum width is bound to provide the correct strength to carry the imposed loads.
Size Thru Bore (L) – The distance thru bore should be sufficient to allow a long enough important to withstand the torque transmitted by the shaft. This also steps the stability 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 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 just 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.

Our regular solitary strand roller chain sprockets are manufactured with hardened the teeth (for tooth counts under 30), used premium quality SAE 1045 metal material, and are finished with black-oxide for corrosion resistance.
To start 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 trouble finding or choosing your sprocket please contact our customer support department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are made to run two single-strand type roller chains, this is where the name “dual single” originated from. Typically these sprockets are A style but both BTB taper bushed and QD style is available from stock. Our double solitary sprockets are produced with hardened teeth and have a dark oxide coating for excellent performance and hook corrosion resistance. Stock sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon ask for. 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 vital that you note is that despite the fact that these sprockets are double sprockets they will not double-strand roller chain. The charts below show the in-stock dual one sprocket sizes and have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to describe their sprockets. Though, through the entire general background of roller chain sprockets almost every manufacture utilizes four different types of sprockets and has followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or just “plate sprocket” can be a set 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 usually 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 begins with a prefix except when previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles along with various 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 aspect parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also referred to as “quick detachable” use a tapered bushing that is bolted in to the bore that is machined in the sprocket. When the bushing is usually inserted in to the sprocket is usually compresses onto the shaft, which gives 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’s bolted to a sprocket to supply an overload gadget. If the torque ranking is usually 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 part quantity, standardly the chain pitch will be written first, then your hub style or code, and followed by the number of tooth the sprocket has. If the sprocket is definitely multi strand there will most often be a letter prefix at the beginning of the part amount.
