| 160 | 50.80 | 28.58 | 31.55 | 222.4 |
Dimensions per ANSI/ASME B29.1. Tensile values are the standard minimum ultimate tensile strength (single strand), not working load — apply an appropriate safety factor. ANSI 25 and 35 are rollerless (bushing) chains; the diameter shown is the bushing OD. Confirm exact data against the manufacturer’s data sheet for your order.

Dimensions per DIN 8187 / ISO 606 (B series). Tensile values are the standard minimum ultimate tensile strength (single strand), not working load — apply an appropriate safety factor. Confirm exact data against the manufacturer’s data sheet for your order.
What to Check
buying checklist- Chain No.Match your existing chain: ANSI 40–160 or DIN 08B–32B
- StrandsSingle, duplex, triplex — tensile scales with strands
- MaterialCarbon steel standard; stainless on request
- LubricationPer application — discuss sealed options for dusty duty
- LengthCut to length or endless; MOQ 1 meter
Customization
Non-standard pitches, extended pins, and special attachments are reviewed against your drawing; lead time confirmed per order (typically about one month).
MOQ 1 meter. FOB / CIF / CFR / EXW. Lead time about 1 month. Nearest ports: Shanghai, Ningbo.
