When a drive calls for a half-inch pitch chain, the ASA 41 from DONGHUA is one of the sizes our customers ask about most. It links parallel shafts on machines where space is tight and loads stay in the light to medium range, and it sits in the power transmission lineup we supply to plants and shops across the USA, Canada, Mexico and South America.
Reading the designation helps with selection. ASA 41 is a roller chain from the ASA series, and the numbers carry the key measurements: 12.7 mm pitch, 7.77 mm roller diameter and 6.38 mm inside width. Those three values are what you match against your sprocket before ordering, because a chain that looks close in size will not seat correctly if the pitch or inside width differs.
Roller chains of this size turn up in low- and medium-power drives: light conveyors, packaging equipment, agricultural machinery, lifting systems and synchronization mechanisms. Food, textile and packaging operations use them as well, since the roller-to-sprocket engagement keeps motion steady and limits wear on both parts.
Before you commit to a size, look at the power being transmitted, the speed the drive runs at and the conditions around it. Confirm the sprockets are the same series and pitch. At installation, align the shafts and set tension properly so the chain does not jump or wear out early, and keep up with lubrication to hold down noise and extend the working life of the drive.
If you are matching a chain you already have, send the part number, the link count or the pitch you need and our team can point you to an equivalent in the same series or from another brand we carry. Chains with attachments such as pusher plates or extended pins can also be quoted. To get started, message the code ASA 41 to us on WhatsApp or by email and we will help you confirm the right chain for your application.

Frequently asked questions
- What does the ASA 41 designation tell me?
- It identifies a roller chain in the ASA series with a 12.7 mm (half-inch) pitch. The 41 number sets the size and series, which places it among general-purpose chains for light and medium power drives.
- Are connecting links included with the chain?
- Chains in this size normally ship in standard rolls, and whether a connecting link is included can vary. Send us a message on WhatsApp and we will go over the options and the length you need.
- How can I confirm it fits my sprocket?
- Check that the sprocket is made for ASA 41 chain, meaning the same 12.7 mm pitch and the same inside width. If you are unsure, share the sprocket part number or a photo and we will help you verify it.
