RS Sprocket Fit bore
- We process the shaft hole, keyway, and tapped hole before shipping.
- There is no need for the customer to perform any additional work, and the product can be used as is.
- We have two types of products available, so please choose the one you prefer.
- * Fit Bore stock items: You can choose from a list of stock items with shaft holes, keyways, and tapped holes already machined.
- * Fit Bore Quick delivery models and made-to-order products: We can also perform additional processing on products that are not listed in the inventory list within the set range.
Features
- - The details of shaft hole processing and keyway processing are coded in the product name, so the customer's order details can be communicated accurately.
- ・ Fit Bore Drawing Library allows customers to check the details of their orders in advance using drawings. (See the banner above.)
- - The shaft hole, keyway, and tapped holes are already processed, so the product can be used as is after it arrives at the customer's site.
Note: When selecting sprocket specifications
- You must select a sprocket that is compatible with your operating environment and the chain specifications you are using. For details, please refer to the compatibility chart for various chains and sprockets.
If you require bearing hole processing, please click here. If you require materials other than steel or stainless steel or surface treatment, etc., these will be special orders, so please contact us here.Catalogs and Instruction Manuals

|
| 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.
