Choosing Tsubaki Attachment Chains This is how a Tsubaki part number for attachment chain will read….. ATTACHMENT CHAINS
NOTES

2L
R
B
Chain Size
Material (see chart)
Attachment (see chart)
Spacing Even pitch = 2L (can be pin link or roller link) Odd pitch = 3L (can alternate pin or roller link)
(can be pin or roller only with offset)
R = Riveted C = Cottered
B = 10 foot box (chain can be supplied in any length requested)
How to order attachment chains: 1. Chain Size 2. Material – see guide above 3. Construction – riveted or cottered
4. What kind of attachment – see listing above 5. Spacing – Distance between attachments
a. Even pitch spacing attachment is on the pin link or roller links (Please specify) b. Odd pitch spacing – attachment will alternate inside link (Roller) outside link (pin). Attachment can also appear on outer links at odd pitch spacing using offset links. 6. Length of chain – Count number of attachments and spacing 7. Repeats – If spacing is unusual, how often does a group of attachments repeat.
