Tritan 50SDS25H sprocket for power transmission

This new Tritan sprocket is a single-strand component built for ANSI 50 roller chain with a 5/8 in pitch. It carries 25 hardened teeth and a black oxide finish on steel. The hub is configured for an SDS quick-detachable bushing with a maximum bore of 2 in. It suits maintenance teams and OEM builders replacing worn driveline parts.

Check chain pitch and bushing compatibility before

Verify that the existing drive uses ANSI 50 chain with a 5/8 in pitch and that the SDS bushing matches the shaft diameter up to 2 in. The hub projection measures 1.157 in and the length through bore is 1 1/2 in, so confirm axial clearance on the shaft. The outside diameter is 5.32 in and the pitch diameter is 4.987 in for guard and spacing checks.

Hardened teeth and black oxide finish resist wear

The 25 hardened teeth engage the chain with a tooth width of .343 in, reducing elongation effects during continuous running. Black oxide coating adds corrosion resistance without changing the 5.32 in outside diameter. The one-sided hub design keeps the assembly compact while the SDS quick-detachable fit allows removal without special tools.

Questions about this item

What comes in the box with the Tritan 50SDS25H sprocket and what must be purchased separately?

The box contains the hardened steel sprocket with 25 teeth, 5.32 in outside diameter and 1.157 in hub projection. An SDS quick-detachable bushing is not included and must be bought separately.

Which specification decides whether this sprocket fits my chain?

The sprocket is built for ANSI 50 chain with 5/8 in pitch and 0.343 in tooth width; match those two figures to your chain to confirm fit.

What does the 4.987 in pitch diameter mean once the sprocket is mounted?

It sets the effective rolling radius that determines chain speed and torque transfer when the sprocket is secured on an SDS bushing up to 2 in bore.
