Behind the part quantity 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 definitely changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the component quantity if the sprocket is produced from a particular material. This designation could be placed in the front of the part quantity 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 – Since the bottom level diameter (BD) of a sprocket with odd quantity 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 may be the measurement from the end of the sprocket tooth across to the corresponding stage directly across the sprocket. It really is comparatively unimportant as the tooth size 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) – Is the distance over the hub in one side to another. This diameter must not go beyond the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension depends upon 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 provide for chain engagement and disengagement. The minimal width is limited to provide the correct strength to carry the imposed loads.
Duration Thru Bore (L) – The distance 
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 replacing them can cost a lot of time and money. Additionally, the efficiency of a conveyor or drive depends upon sprocket-chain interaction. Using the right sprocket is just as important as selecting the most appropriate chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are engineered to execute well under pressure and 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 meet up with both ANSI and ASME criteria.

Our knowledgeable staff, excellent products, and unbeatable prices will be the reasons for our A+ BBB rating!
SINGLE STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We stock a complete line of each type! Our regular single strand roller chain sprockets are manufactured with hardened the teeth (for tooth counts under 30), used superior quality SAE 1045 metal material, and are finished with black-oxide for corrosion level of resistance.
To start shopping simply choose what chain size you are employing with your sprocket. Following 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 trouble finding or selecting your sprocket please get in touch with our customer service department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are created to run two single-strand type roller chains, this is where the name “dual single” originated from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from share. Our double single sprockets are manufactured with hardened the teeth and have a dark oxide coating for superior performance and a slight corrosion resistance. Stock sizes of double single 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 due to our quick response in-house machine shop. Something important to note is that even though these sprockets are double sprockets they’ll 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 use different “terms” or nomenclature to describe their sprockets. Though, throughout the 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 known as A-Plate or just “plate sprocket” can be a flat sprocket plate-wheel without hubs that extrude on 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 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 regular styles and also many 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 Single (these sprockets are made to operate two single-strands of roller chain part parallel to one another)
COMMON SPROCKET STYLES
QD style sprockets, also known as “quick detachable” use a tapered bushing that’s bolted into the bore that’s machined in the sprocket. When the bushing is certainly inserted in to the sprocket can be 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 hold 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 device. If the torque ranking is exceeded the shear device 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 quantity, standardly the chain pitch will be created first, then the hub style or code, and accompanied by the number of tooth the sprocket has. If the sprocket is definitely multi strand there will frequently be a letter prefix at the beginning of the part amount.
