The following defines terminology and provides guidance to help select the best sprocket for a given application. In the event that further assistance is required, please call U.S. Tsubaki customer service at (800) 323-7790.
Maximum Bore Diameter: Refers to the maximum bore size diameter a sprocket can be machined to without compromising structural integrity. This term is associated with both “B” and “C” style sprockets. Please refer to Figure 4 for illustration. Length Thru Bore: “LTB” Refers to the inside hub diameter and the length to which it was machined. This machined length must be long enough to accommodate the proper size keyway to withstand shear and torque stress induced by the rotating shaft. Please refer to Figure 4 for illustration. Plain Bore: Associated with “A,” “B” and “C” style sprockets where there is no special machining performed to accommodate keyways or set screws, only a hole to accommodate shaft diameter. Please refer to Figure 6 for illustrations of Plain Bore sprockets. Finished Bore: Associated with “B” and “C” style sprockets where the inside diameter of the hub is machined with a standard keyway and two set screws. Finished bore hubs can also be machined to specific requirements depending on the needs of the application. Please refer to Figure 5 for an illustration. Sprocket Hub Style: U.S. Tsubaki manu- facturers various sprocket hub styles to meet the application requirements of our customers. Please refer to Figure 6 for the various stock style hub configurations offered by U.S. Tsubaki.

Basic Terminology ANSI Chain Pitch:
CALIPER DIAMETER
Figure 3 - Measuring sprocket outside diameter
01
The term “chain pitch” refers to the roller pin center to roller pin center dimension of a given chain. The pitch is always measured in 1/8" increments. Please see Figure 1 for an illustration of how to measure chain pitch. Please see Table 1 for referencing ANSI Standard chain pitch sizes. Caliper Diameter: The term “caliper diameter” refers to the dimension measured from sprocket tooth valley to sprocket tooth valley on the opposite side (180°) of the sprocket. This dimension is used to measure the diameter of the sprocket plate (not including sprocket teeth). On sprockets that have an odd number of teeth, the measurement would be taken from the valley of one tooth to the valley as close to 180° on the opposite side of the sprocket. Please reference Figure 2 for an illustration of how this dimension is measured. Sprocket Outside Diameter: Sprocket outside diameter is the measure- ment from sprocket tooth peak to sprocket tooth peak on the opposite (180°) side of the sprocket. For sprockets with an odd number of teeth, the measurement would be taken from the peak of one sprocket tooth to the peak of a tooth as close to 180° degrees as possible. Please refer to Figure 3 for an illus- tration as to how this dimension is measured.

Small and Large Roller Double Pitch Sprockets:
QD ® Sprockets: This type of sprocket is used in applications where higher working loads are prevalent, and high clamp loading on the drive shaft is desirable. Sprockets with tapered bushings will fall into the QD ® , Split-Taper or TAPER-LOCK ® family. QD ® bushings are flanged, and most commonly utilize large anchor bolts around the circumference of the flange to retain itself to the sprocket. However, this style of bushing is also available in a weld on hub configuration. One of the primary advantages the QD ® bushing offers is its ease of installation and removal. It also provides superior clamp force, and aligns the sprocket 90 0 to the drive shaft to assure proper alignment. Please refer to Figure 10 for an illustration of a QD ® sprocket. TAPER-LOCK ® Sprockets: TAPER-LOCK ® bushings are similar to QD ® style bushings in that they both utilize a split through the taper and flange to provide a true clamp on the shaft that is equivalent to a shrink fit. This type of bushing is retained to the sprocket with a series of set screws on the outside diameter of the bushing running parallel to the shaft, or can be welded to the sprocket itself. With TAPER-LOCK ® bushings, there is no need for a set screw over the drive shaft key. TAPER-LOCK ® bushings offer flexibility in that they allow multiple sized bores for a single bushing size. Please refer to Figure 11 for an illustration of a TAPER- LOCK ® sprocket. Steel Split Sprockets: Split sprockets are slit through the entire diameter of the sprocket to allow ease of installation and removal. The sprocket halves are held together by bolts located on either side of the hub. This particular style is available in chain pitch sizes of 40 through 240, and bore diameters of 3/4" through 6" depending on chain pitch selected. Figure 12 provides an illustration of a steel split sprocket.

Used with double pitch conveyor series roller chains. These chains are available with either the standard small roller diameter (i.e.: 2040, 2050, 2060, 2080, 2100) or a larger diameter chain roller style (i.e.: 2042, 2052, 2062, 2082, 2102). Sprockets are available from stock to accommodate either style. This type of sprocket is primarily used in conveying applications where torque requirements are lower, and long service life is critical. Please refer to Figure 7 for an illustration of a standard and double pitch sprocket for comparison purposes. Multiple-Strand Sprockets: This type of sprocket is commonly used in applications where higher torque and power requirements are needed. The spacing between the rows of teeth corresponds with the center-line of chain strands. Due to the added width of chain, the “LTB” of multiple strand sprockets is correspondingly longer. This style of sprocket is available in 40 through 160 chain pitch with plain, finished or TAPER-LOCK ® /QD ® style hubs. Please refer to Figure 8 for an illustration of a Multiple-Strand sprocket. DOUBLE PLUS ® Sprockets: This type of sprocket is specifically designed to work with DOUBLE PLUS ® chain. This style of sprocket is used in conveyor applications where product on the conveyor is propelled at twice speed of the drive system powering the conveyor. The main benefit of incorporating DOUBLE PLUS ® chain and sprockets is less noise and longer chain life. Please refer to Figure 9 for an illustration of a DOUBLE PLUS ® sprocket.

British Standard Sprockets: This style of sprocket is similar to an ANSI style sprocket with the exception of the fact that it is designed to propel British Standard Chain. British Standard Chain has slightly different dimensions with regard to chain pitch and roller diameter. ANSI Standard chain pitch is measured in 1/8" increments (pin to pin), whereas British Standard follows a 1/16" pin to pin spacing. Please see Figure 13 for an illustration of how to measure British Standard chain pitch. Double Single Sprockets: This type of sprocket is commonly used in applications where two or more items are powered by a common drive shaft. The space between the sprocket plates is wider than a multi-strand sprocket, and allows two separate strands of chain to engage without contacting each other. With this type of sprocket, one strand of chain may exit in a different direction than the other. For example, one strand exiting towards the ceiling and the other running parallel to the floor. Please refer to Figure 14 for an illustration of a Double Single sprocket. Idler Sprockets: This type of sprocket is used in applications where the drive chain may experience slack due to long lengths, non-adjustability of the driven shaft, or where the chain has to be guided around an obstruction. Use of Idler Sprockets prevents chain whipping and uneven distribution of load. This type of sprocket can also be used in applications where the drive chain may experience direction reversal, or in applications where the chain may experience whipping. Having idler sprockets touching the outside of the chain would be beneficial. Please refer to Figure 15 for an illustration of an Idler Sprocket.

Altered !! : The term “Altered” applies to a sprocket that requires a minor modification to the standard configuration to fulfill the requirements of the application at hand. Some examples of common alterations include: rebore to a different size than standard, different set screw location than standard, drilling of holes into sprocket plate for accessory mounting, non-standard keyway size, etc. A complete list of common alterations is available in the engineering section of this catalog. It should be noted that adding the prefix "A" is used only when an alteration is required. It is not necessary for standard products and only applies when a non-standard feature is required. Fraction Legend for Hub Bore Size: The following table should be used to define the hub bore size associated with “Finished Bore” stock sprocket product. Note that a letter designator is used to represent a fractional dimension. For example: a 1B hub bore equates to a sprocket bore of 1.125" inside diameter.
