Product Info Sprockets and Pin Gear Drive
A sprocket is a type of gear, also known as a chainwheel.
It is a mechanical element that can transmit the rotation of the shaft to the chain and the tension of the chain to the shaft.
Depending on whether or not a hub is included, there are types such as Type A (flat type), Type B (single hub type), and Type C (double hub type).
It is available in high strength and corrosion resistant specifications, and can be used in a variety of situations.
*Sprockets for Plastic modular chain, Top chain, and Plastic block chain can be viewed on the product page for each chain.

Sprocket and Pin gear drive related information
Features
- When used for Drive chain transmission, a large reduction ratio can be achieved by combining different numbers of teeth (generally up to 1:7).
- ・You can choose from a wide lineup of products, including not only pilot bore products but also products with machined shaft holes and additionally machined shaft holes (steel, stainless steel, resin, surface treatment, etc.).
- -We offer a lineup of materials and specifications to suit your application.
- ・Sprockets for pin gears with special tooth profiles can be used in combination with attachment chains, pin racks, and pin wheels for linear and rotary drive applications rather than power transmission purposes.
You can use it.
Structure
RS sprockets come in four types of structures specified by JIS.
| Model code | A-type (flat plate type) |
B type (Single hub type) |
C type (double hub type) |
SD type (single dual) |
|---|---|---|---|---|

|
| RS-HT chain (SUPER-H, HT, etc.) multiple strand Note 1 | A shape that allows two single strand chains to be hung at the same time | |||
| HB type | HC type | |||
| Use depending on the structure | It is used when attaching to a rotating body such as the center member of a torque limiter. | It is the most versatile. | Used when the key surface pressure is insufficient with the large driven sprocket or B type. | It is used by hanging two single strand chains at the same time. |
Note
1. The total tooth width (transverse pitch) of RS-HT chain multiple strand (HB type, HC type) is different from the standard.
Shaft fastening method
There are three types of shaft hole specifications for mounting a sprocket to a mating shaft:
| series | Exterior | Specification |
|---|---|---|
| Standard pilot bore |
|
|
| Fit Bore |
|
|
| Lock Sprocket |
|
|
Material and surface treatment
We offer a lineup of specifications and materials to suit your application, including steel, surface-treated, stainless steel, and resin.
| Standard steel | Carbon steel for machine structures | |
|---|---|---|
| Surface Treatment | Carbon steel for machine structures + black oxide finish | You can choose from shaft hole processed products (sprocket Fit Bore). |
| Carbon steel for mechanical structures + electroless nickel-phosphorus plating | You can choose from shaft hole processed products (sprocket Fit Bore). | |
| Carbon steel for mechanical structures + electrogalvanized (trivalent chromate treatment) | You can choose from shaft hole processed products (sprocket Fit Bore). | |
| Carbon steel for machine structures + other special surface treatments | ||
| Environmental resistance | Stainless steel, titanium, and other special materials | |
| resin | Engineering plastic nylon resin MC901 special (blue) *Only for RS35, 40, 50, 60 |
