Behind the part number a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket can be a QD or taper bushed design the guts 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 amount if the sprocket is manufactured 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 – Because the bottom level diameter (BD) of a sprocket with odd amount of teeth can’t 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 as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The exterior diameter is 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 length is not vital to correct meshing to with the chain. The exterior diameter may vary depending on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be 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.
Optimum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper power. The dimensional allowance should be designed for keyway and established 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 bound to provide the proper strength to transport the imposed loads.
Duration Thru Bore (L) – The distance thru bore must be sufficient to allow an extended enough essential to withstand the torque transmitted by the shaft. This also actions 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 machines can’t operate without their drive teach sprockets, and replacing them can cost lots of time and money. Additionally, the efficiency of a conveyor or drive depends upon sprocket-chain interaction. Using the proper sprocket is simply as important as selecting the most appropriate chain.

Our regular one strand roller chain sprockets are manufactured with hardened teeth (for tooth counts under 30), used premium quality SAE 1045 metal material, and are finished with black-oxide for corrosion resistance.
To start out shopping simply select what chain size you are using with your sprocket. Following select the type needed, lastly select the desired tooth count and possible accessories needed, then you are ready to get your sprockets! If at any point you have queries or problems finding or picking your sprocket please get in touch with our customer support department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are created 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 share. Our double single sprockets are produced with hardened the 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 could be manufactured upon request. We are able to also supply quick response custom re-bores and MTO specialized double single sprockets because of 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 double solitary sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to describe their sprockets. Though, throughout the general history 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 known as A-Plate or just “plate sprocket” can be 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 on one side.
Style C, also called C-Hub sprockets is certainly 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 will start 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 many other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are made to operate two single-strands of roller chain side parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also referred to as “quick detachable” use a tapered bushing that is bolted into the bore that’s machined in the sprocket. When the bushing can be inserted in to the sprocket is certainly compresses onto the shaft, which provides a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another design of interchangeable bushed sprockets that delivers 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 provide an overload gadget. If the torque ranking is definitely exceeded the shear gadget 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 component quantity, 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 frequently be a letter prefix at the beginning of the part number.
