U.S. TSUBAKI ATC CHAIN
HP-T Type HP-T type ATC chain is based on the HP type with steel tool holder. The inner diameter of the pin is tapered and a retaining function is installed on the pin. Economical: Additional installation of the tool holder is not necessary. Accurate holding:As the tool holder is combined with the chain, backlash is reduced. Compactness: Pin outer diameter and link plate width are smaller than those of HP type. ATC CHAIN HP-T TYPE WITH TOOL HOLDER
1) U.S. Tsubaki standardized ATC chain is designed with pull stud, key, number plate and plastic sleeve. An engineering plastic sleeve is fitted to prevent contact with the metal taper parts and protect the shank from being scratched. 2) Attachment chains other than the listed ATC chain line-up are also available to satisfy your special requirements.

Note: 1. If the extracting force required is large, please consult U.S. Tsubaki. 2. Chain weight less pot shows for MAS standard.
5. Refer to page B-89 for key and number plate dimensions. 6. Shanks No. 45 and 60 are also available upon request.
3. Chain pitches different from those above are also available. 4. The minimum chain pitch that can be manufactured is:
Shank No. 40: P = 3.543 inch Shank No. 50: P = 4.921 inch Safety device for HP-T type chain (optional)
In the case of horizontal drive HP-T type chain (with tools vertically suspended), we can provide the tool holder with an optional safety device. The safety device prevents the tool from falling out of the tool holder during operation.
Note: The safety device is not available for Shank No. 40. Instead, we suggest using a higher tool extraction force.
Pushing the safety device pin by the cylinder easily releases the tool from the retention knob by spring force.
