Behind the part number a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is a QD or taper bushed style the center letter for the hub designation is definitely changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the component number if the sprocket is produced from a particular material. This designation can be placed in leading 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 areas.
Caliper Diameter – Since the bottom diameter (BD) of a sprocket with odd number of teeth cannot be measured directly, caliper diameters are the measurement over the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which may be 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 outside 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 length is not essential to appropriate meshing to with the chain. The outside diameter may vary based on the kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance across the hub in one side to some other. This diameter must not surpass the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper strength. The dimensional allowance must be made for keyway and arranged screws.
Face Width (T) – Encounter width is limited in its optimum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimal width is limited to provide the proper strength to transport the imposed loads.
Size Thru Bore (L) – The space thru bore should be sufficient to allow an extended enough important 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 devices can’t operate without their drive teach sprockets, and changing them can cost lots of time and cash. Additionally, the efficiency of a conveyor or drive depends upon sprocket-chain interaction. Using the proper sprocket is just as important as deciding on the best chain. At Ever-power Roller Chain, we offer a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are designed to execute well under pressure and so are resilient. The roller chain sprockets accessible in our shop include single-strand roller chain sprockets, double strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets fulfill both ANSI and ASME specifications.
We’re positive you’ll end up being happy when you get industrial chain sprockets in our store, because they’ll last you a long time. If you’re uncertain what sprockets will be the ones you will need for your machine, make sure you don’t hesitate to give us a call. Our knowledgeable staff, superior items, and unbeatable prices will be the known 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 stock a complete type of each type! Our regular solitary strand roller chain sprockets are manufactured with hardened the teeth (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 shopping simply select what chain size you are using with your sprocket. Following select the type needed, finally select the preferred tooth count and possible accessories needed, you then are ready to obtain your sprockets! If at any stage you have queries or problems finding or selecting your sprocket please get in touch with our customer service department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are created to run two single-strand type roller chains, that’s where the name “dual single” originated from. Typically these sprockets certainly are a style but both BTB taper bushed and QD design is available from share. Our double single sprockets are produced with hardened teeth and have a black oxide coating for superior performance and a slight corrosion resistance. Share sizes of double one sprockets range from ANSI #40 – #160 but additional sizes can be manufactured upon request. We are able to also supply quick reaction custom re-bores and MTO specialized double single sprockets because of our quick response in-house machine shop. Something important to note is that despite the fact that these sprockets are double sprockets they’ll not double-strand roller chain. The charts below display the in-stock dual one sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “conditions” or nomenclature to describe their sprockets. Though, through the entire general history 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 usually a flat 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 using one side.
Style C, also referred to as C-Hub sprockets is a sprocket with a hub that extrudes on both sides.
Style 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 standard styles in addition to several 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 side parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also referred to as “quick detachable” utilize a tapered bushing that is bolted in to the bore that’s machined in the sprocket. When the bushing is definitely inserted in to 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 design of interchangeable bushed sprockets that provides a positive hold 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 can be 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 quantity, standardly the chain pitch will be written first, then the hub style or code, and followed by the number of teeth the sprocket has. If the sprocket is certainly multi strand there will frequently be considered a letter prefix at the start of the part amount.
