Heavy Duty Double Roller Chain Sprocket With Type B Hub Featuring 15 Teeth 5/8 Inch Pitch For 50 Series Chains Hardened Steel Construction Offers Rock Solid Setup With Reboreable 0.75 Inch Bore Built Tough For Grease Monkey Rigs

Single Duplex Chain Sprocket 15t 5/8 Pitch Steel Hub 0.75 In Bore
✔️ Strong carbon steel supports roller chain drives and shaft torque

This single duplex drive sprocket meshes with two parallel 50 series roller chains to transfer rotational power across straight-line mechanical setups. Shop owners and fabricators typically mount this unit on industrial equipment, conveyor lines, and garage work rigs that demand steady torque transmission without slippage.

✅ Accepts two parallel 50 series roller chains with 5/8 inch pitch spacing
✅ Features a Type B hub extension for secure shaft mounting and full depth keyways
✅ Includes a 0.75 inch reboreable bore to match standard industrial driveshafts
✅ Provides a 1.045 inch face width to keep dual chain rows aligned under load
✅ Built from hardened high carbon steel to withstand continuous grease monkey duty

💡 What makes duplex chain drives a handy choice for heavy shop equipment?
Switching from single to twin row power transmission lets motors push more weight without stretching out the layout. Here is why mechanics swear by this setup:
- Duplex sprockets split torque across two parallel tracks to handle heavier load ratings smoothly
- Standard ANSI roller chain links slide right onto the 5 8 pitch groove for quick swaps
- Straight line alignment keeps tension even so your rig runs quiet under heavy shifts
