When you're building or repairing a drive system, the part that actually transfers power from the motor to the machine matters more than the brand name on the box. Do you need a sprocket that meshes with a chain, a length of roller chain to carry that power, a rigid coupling to join two shafts directly, or a plastic coupler for a conveyor line? The answer changes what you should spend. In the bearings couplings power transmission category, these four products cover different jobs, and their prices range from $24.99 to $69.71.
Quick Take
- The Tsubaki H40B24F-7/8 sprocket is the least expensive at $24.99, sized for motorcycle and scooter drivetrains.
- The Tsubaki H60B13F-1 1/4 roller chain is $36.00 and made in the United States for chain-drive builds.
- The rigid shaft coupling is $34.59 and works well for 3D printers, model cars, boats, and airplanes.
- The Delrin coupler is $69.71 for two pieces and is designed for line shaft conveyor sprockets.

Product Notes
NEW TSUBAKI POWER TRANSMISSION COMPONENTS H40B24F-7/8 SPROCKET

At $24.99, the Tsubaki H40B24F-7/8 sprocket is the least expensive part in this group. It's a new sprocket imported from Japan and sized with a 7/8-inch bore. If you're repairing a motorcycle or scooter chain drive, this is a straightforward replacement component. The bore and tooth count are fixed, so you need to know your shaft diameter and chain pitch before ordering. Because it's a single sprocket, factor in the cost of a matching chain and any second sprocket your drive requires.
NEW TSUBAKI H60B13F-1 1/4 ROLLER CHAIN power Transmission Components

Tsubaki's H60B13F-1 1/4 roller chain comes in at $36.00 and is made in the United States. It carries the same Tsubaki branding as the H40B24F sprocket, so it works with that line when you're assembling a chain drive. The chain provides the flexible link that transfers power between two sprockets, and the product includes a UPC for reference. The limitation is that it's just the chain: you'll need compatible sprockets on both ends, and because the 1 1/4 is a model identifier, confirm that it matches the pitch your sprockets expect.
Rigid Shaft Coupling Coupler Motor Transmission Connector Sleeve DIY Motor Motor

Priced at $34.59, the rigid shaft coupling is a steel connector built for hobby and DIY projects. It suits 3D printers, model cars, boats, and airplanes, and it uses a set-screw clamp design for a secure hold. The steel body keeps inertia low while providing high torque rigidity, which is useful for small motor shafts. The trade-off is that a rigid coupling does not tolerate eccentricity or misalignment; you have to align the two shafts perfectly before tightening. Also, bore sizes vary across the listed range, so select the version that fits your motor shaft and rod.
Delrin Coupler Plastic Sprocket Coupling Chain for Line Shaft Conveyor - Qty 2

The Delrin coupler is the most expensive option at $69.71 for a quantity of two. It's a plastic chain coupler made for line shaft conveyors and fits the common 4016 sprockets. Unlike steel chain couplers, which are greasy and have small parts that constantly need attention, this Delrin design wraps around the sprocket teeth and locks with a pin for a clean, quick install. If you maintain a conveyor line with 4016 sprockets, this is a direct replacement. The limitation is that it's purpose-built for that sprocket size, so it won't work on other conveyor sprockets without also changing the sprockets.
Final Recommendation
Choose the Tsubaki H40B24F-7/8 sprocket when you need a motorcycle or scooter drivetrain component and your shaft accepts a 7/8-inch bore. Pick the Tsubaki H60B13F-1 1/4 roller chain when you're building a new drive and need the connecting link. Go with the rigid shaft coupling when you're working on 3D printers, model cars, boats, or airplanes and can guarantee alignment. Select the Delrin coupler when you're servicing a line shaft conveyor with 4016 sprockets and want a cleaner install than steel chain couplers.
