Behind the part number a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket can be a QD or taper bushed style the guts letter for the hub designation is definitely changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the component quantity if the sprocket is produced from a particular material. This designation can be placed in leading of the part number or behind, if it is 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 number 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 is 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 outside diameter is the measurement from the tip of the sprocket tooth across to the corresponding stage directly across the sprocket. It is comparatively unimportant as the tooth length is not vital to appropriate meshing to with the chain. The exterior diameter may vary based on the type of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub from one side to another. This diameter should never surpass the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by 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 limited in its optimum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimal width is limited to provide the proper strength to transport the imposed loads.
Length Thru Bore (L) – The space thru bore must be sufficient to allow an extended 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 changing them can cost lots of time and money. Additionally, the overall performance of a conveyor or drive depends on sprocket-chain interaction. Using the proper sprocket is simply as important as choosing the right chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are designed to perform well under pressure and so are long lasting. The roller chain sprockets accessible in our store include single-strand roller chain sprockets, double strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets satisfy both ANSI and ASME criteria.
We’re positive you’ll become happy when you buy industrial chain sprockets in our store, because they’ll last you a long time. If you’re not sure what sprockets will be the ones you need for your machine, please don’t hesitate to give us a contact. Our knowledgeable staff, excellent products, and unbeatable prices are the reasons for our A+ BBB ranking!
Solitary STRAND ROLLER CHAIN SPROCKETS
There are six different standard styles of sprockets for single strand roller chain. We share a complete type of each type! Our standard one strand roller chain sprockets are manufactured with hardened teeth (for tooth counts under 30), used premium quality SAE 1045 steel material, and are finished with black-oxide for corrosion resistance.
To start shopping simply choose what chain size you are employing with your sprocket. Next choose the type needed, finally select the desired tooth count and feasible accessories needed, then you are ready to obtain your sprockets! If at any point you have questions or trouble finding or picking your sprocket please contact our customer service department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are made to operate two single-strand type roller chains, that’s where the name “dual single” came from. Typically these sprockets are A design but both BTB taper bushed and QD design is available from share. Our double single sprockets are produced with hardened tooth and have a dark oxide coating for superior performance and hook corrosion resistance. Share sizes of double single sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon ask for. We can also supply quick reaction 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 even though these sprockets are double sprockets they will not double-strand roller chain. The charts below show the in-stock double single sprocket sizes and also have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “conditions” or nomenclature to spell it out their sprockets. Though, throughout the general background of roller chain sprockets nearly every manufacture utilizes four various kinds of sprockets and has followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or simply “plate sprocket” is usually a set sprocket plate-wheel with no 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 known as C-Hub sprockets is definitely 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 and also many other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
E – 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 design sprockets, also referred to 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 certainly inserted into the sprocket is definitely 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 definitely exceeded the shear device 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 part number, standardly the chain pitch will be created first, then your hub design or code, and accompanied by the number of teeth the sprocket has. If the sprocket is usually multi strand there will most often be considered a letter prefix at the start of the part quantity.
