This double-row sprocket with hub is a power transmission component supplied by MR and manufactured by EMMAR. It runs on 5/8" pitch roller chain and carries 57 teeth, and it is machined from SAE 1045 steel. With two toothed rings on a single hub, it lets one shaft position drive two chains at once or widen the contact area without adding a second sprocket.
The part is identified by two values: the 5/8" pitch, which is the distance between roller centers on the chain it takes, and the 57-tooth count. SAE 1045 is a medium-carbon steel chosen for a balance of toughness and resistance to wear. In this double sprocket with hub design, both toothed rings sit on one central hub that mounts to the shaft, so the rows turn together and share the working load.
You will find this style of sprocket on chain conveyors, bucket elevators, food processing machinery, packaging lines and general transmission drives. A double row makes sense when a single drive wheel has to run two chains, such as feed and return runs, or when the drive needs more contact width while keeping just one mounting point on the shaft.
When specifying a replacement, work through the chain pitch, tooth count, shaft diameter and fixing method, whether that is a keyway, a set screw or a taper bushing. Confirm that the two rows line up and check the center distance between shafts. If the sprocket sits out of alignment, the teeth and chain wear faster. Lubrication and correct chain tension also affect how long the assembly lasts.
Other tooth counts, pitches or hub sizes can be sourced. MR Industrial Accessories LLC also supplies bearing housings, ANSI chains, pulleys, bearings and seals.

Frequently asked questions
- What does "double sprocket with hub" mean?
- It means two toothed rings are mounted on one central hub that attaches to the shaft. Both rows rotate together, so they can drive two chains in parallel or increase the contact width, depending on how the equipment is built.
- Can I get this sprocket with a different number of teeth?
- Yes. Since MR supplies this line, sprockets with other tooth counts in the same pitch or in other pitches can be sourced. Send the tooth count, pitch and shaft dimensions by WhatsApp and we will quote the variant.
- How do I check if this sprocket fits my chain?
- Chain pitch is the key. This sprocket takes 5/8" pitch chain. Confirm your chain matches that pitch, and that the tooth count and shaft diameter suit your mounting. If anything is unclear, send us your equipment data and we will advise.
