Behind the part amount 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 center letter for the hub designation is usually changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the component quantity if the sprocket is produced from a special material. This designation can be placed in leading of the part amount 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 areas.
Caliper Diameter – Because the bottom level diameter (BD) of a sprocket with odd quantity of teeth can’t be measured directly, caliper diameters are the measurement across the tooth spaces nearly 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)
Outdoors Diameter (OD) The exterior diameter may be 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 size is not essential to proper meshing to with the chain. The outside 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.
Optimum 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 bound in its maximum 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 length thru bore must be sufficient to allow an extended enough important to withstand the torque transmitted by the shaft. This also procedures the balance 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 teach sprockets, and changing them can cost lots of time and cash. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain interaction. Using the proper sprocket is simply as important as selecting the most appropriate chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are manufactured to perform well under pressure and are long lasting. The roller chain sprockets accessible in our store include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets meet up with both ANSI and ASME standards.
We’re positive you’ll be happy when you get industrial chain sprockets inside our shop, because they’ll last you a long time. If you’re uncertain what sprockets are the ones you will need for your machine, make sure you don’t hesitate to provide us a contact. Our knowledgeable staff, excellent items, and unbeatable prices are the known reasons for our A+ BBB ranking!
One 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 produced with hardened tooth (for tooth counts under 30), used superior quality SAE 1045 metal material, and are finished with black-oxide for corrosion resistance.
To start shopping simply choose what chain size you are employing 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 point you have questions or trouble finding or picking your sprocket please contact our customer service department and we’ll be happy to help you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are made to operate two single-strand type roller chains, that’s where the name “double single” came from. Typically these sprockets are A style but both BTB taper bushed and QD design is available from share. Our double one sprockets are manufactured with hardened teeth and have a black oxide coating for superior performance and a slight corrosion resistance. Stock sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon request. We can also supply quick response custom re-bores and MTO specialty double single sprockets due to our quick response in-house machine shop. Something vital that you note is that even though these sprockets are dual sprockets they will not double-strand roller chain. The charts below display the in-stock double single sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “conditions” or nomenclature to describe their sprockets. Though, through the entire general background of roller chain sprockets nearly every produce utilizes four different types of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also referred to 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 called B-Hub sprockets is a sprocket with a hub that extrudes on one side.
Style C, also referred to as C-Hub sprockets can be a sprocket with a hub that extrudes on both sides.
Design D, is a sprocket with a detachable bolt-on hub mounted on 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 regular styles and also several 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 One (these sprockets are made to run two single-strands of roller chain part parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also called “quick detachable” make use of a tapered bushing that is bolted into the bore that’s machined in the sprocket. When the bushing is usually inserted into 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 style of interchangeable bushed sprockets that delivers a positive hold on the driven shaft.
Shear Pin sprockets use a shear pin type hub that’s bolted to a sprocket to provide an overload device. If the torque ranking can be exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation with no disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component amount, standardly the chain pitch will be written first, then your hub style or code, and accompanied by the number of tooth the sprocket has. If the sprocket can be multi strand there will most often be considered a letter prefix at the start of the part amount.
