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 changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the component number 
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 will be the measurement across the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle accompanied by the centers of the chain pins as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside Diameter (OD) The outside diameter may be the measurement from the end of the sprocket tooth across to the corresponding point 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 type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub from one side to some other. This diameter must not exceed 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 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 minimum width is bound to provide the correct strength to transport the imposed loads.
Duration Thru Bore (L) – The distance thru bore must be sufficient to allow a long enough crucial 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 can bring your machinery to a grinding halt. Many devices can’t operate without their drive train sprockets, and changing them can cost a lot of time and cash. Additionally, the functionality of a conveyor or drive depends on sprocket-chain interaction. Using the right sprocket is simply 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 manufactured to perform well under pressure and so are resilient. 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 specifications.
We’re positive you’ll become happy when you buy industrial chain sprockets inside our shop, because they’ll last you a long time. If you’re not sure what sprockets will be the ones you need for your machine, make sure you don’t hesitate to provide us a contact. Our knowledgeable staff, excellent items, and unbeatable prices will be the known reasons for our A+ BBB rating!
Solitary 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 produced with hardened teeth (for tooth counts under 30), used superior quality SAE 1045 metal material, and are completed with black-oxide for corrosion level of resistance.
To start out shopping simply choose what chain size you are employing with your sprocket. Next choose the type needed, lastly select the desired 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 will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are designed to run two single-strand type roller chains, that’s where the name “double single” came from. Typically these sprockets certainly are a design but both BTB taper bushed and QD design is available from share. Our double one sprockets are produced with hardened the teeth and have a black oxide coating for excellent performance and hook corrosion resistance. Share sizes of double one sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon request. We are able to also supply quick reaction custom re-bores and MTO specialty 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 will not double-strand roller chain. The charts below display the in-stock dual one sprocket sizes and have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “conditions” or nomenclature to spell it out their sprockets. Though, through the entire general background of roller chain sprockets nearly every produce utilizes four different types 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 called B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also called 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 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 regular styles in addition to many other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double Solitary (these sprockets are created to operate two single-strands of roller chain part parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also known as “quick detachable” utilize a tapered bushing that is bolted into the bore that’s machined in the sprocket. When the bushing is inserted in to the sprocket is certainly compresses onto the shaft, which gives a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another style of interchangeable bushed sprockets that provides a positive grip 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 is exceeded the shear device 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 part quantity, standardly the chain pitch will be created first, then the hub style or code, and followed by the number of the teeth the sprocket has. If the sprocket is usually multi strand there will frequently be considered a letter prefix at the beginning of the part amount.
