Roller chain sprocket

Behind the part number a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is usually a QD or taper bushed design the center letter for the hub designation is changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures will 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 amount 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 – Because the bottom diameter (BD) of a sprocket with odd amount 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 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 end of the sprocket tooth across to the corresponding point directly across the sprocket. It really is comparatively unimportant as the tooth length is not vital to correct 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) – Is the distance over the hub in one side to some other. This diameter should never 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 power. 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 supply for chain engagement and disengagement. The minimal width is limited to provide the proper strength to transport the imposed loads.
Duration Thru Bore (L) – The distance thru bore should be sufficient to allow a long enough crucial to withstand the torque transmitted by the shaft. This also measures 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 train sprockets, and replacing them can cost a lot of time and money. Additionally, the performance of a conveyor or drive depends on sprocket-chain interaction. Using the proper sprocket is just as important as deciding on the best chain. At Ever-power Roller Chain, we provide a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform well under pressure and are long lasting. The roller chain sprockets accessible in our shop include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets fulfill both ANSI and ASME standards.
We’re positive you’ll be happy when you get industrial chain sprockets in our store, because they’ll last you a long time.

Our knowledgeable staff, excellent items, and unbeatable prices are the known reasons for our A+ BBB rating!
One STRAND ROLLER CHAIN SPROCKETS
There are six different standard styles of sprockets for single strand roller chain. We share a complete line of each type! Our standard single strand roller chain sprockets are manufactured with hardened tooth (for tooth counts under 30), used superior quality SAE 1045 steel material, and are completed with black-oxide for corrosion level of resistance.
To start out shopping simply choose what chain size you are using with your sprocket. Next choose the type needed, finally select the preferred tooth count and possible accessories needed, then you are ready to obtain your sprockets! If at any stage you have questions or difficulty finding or choosing your sprocket please get in touch with our customer support 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, this is where the name “double single” came from. Typically these sprockets certainly are a style but both BTB taper bushed and QD style is available from stock. Our double solitary sprockets are produced with hardened tooth and have a dark oxide coating for superior performance and a slight corrosion resistance. Share sizes of double solitary sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon ask for. We can also supply quick response 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 dual sprockets they will not double-strand roller chain. The charts below display the in-stock dual solitary sprocket sizes and have clickable links to the product 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 background of roller chain sprockets almost every produce utilizes four various kinds of sprockets and has followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also referred to as A-Plate or just “plate sprocket” is a flat sprocket plate-wheel without hubs that extrude upon either side.
Style B, also referred to as B-Hub sprockets is a sprocket with a hub that extrudes on 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 attached to 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 and also 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 Solitary (these sprockets are created to run two single-strands of roller chain part parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also called “quick detachable” use a tapered bushing that’s 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 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 hold 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 rating can be exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation with out disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component number, standardly the chain pitch will be written first, then your hub style or code, and accompanied by the number of teeth the sprocket has. If the sprocket can be multi strand there will frequently be considered a letter prefix at the start of the part quantity.
