Nice Apollo 25B24 Limit Sprocket Quick Release for 7200/7300
The Nice Apollo 25B24 is a limit sprocket quick-release component for compatible Apollo 7200 and 7300 style slide gate operators. On these operators, the limit system is separate from the main gate drive chain and is used to help control where the gate stops in the open and closed positions. A worn or incorrect limit sprocket can cause travel problems, unreliable limit engagement, or difficulty servicing the quick-release assembly. This part should be matched to the actual limit assembly on the operator, not just to the general model family. Apollo slide operator parts vary by generation, drive layout, internal-limit versus external-limit design, and sprocket size. When replacing 25B24, inspect the shaft, chain, limit nuts or switches, quick-release hardware, and related bearings or collars so the new sprocket is not installed into a worn mechanical assembly.

Technician Note
If the gate overtravels or stops inconsistently, also inspect the limit chain, switches, limit nuts, shaft hardware, and quick-release engagement. Replacing only the sprocket may not fix a worn limit assembly.
Before Ordering
- Confirm the operator is a compatible 7200 or 7300 style unit.
- Match the original part number to 25B24.
- Check whether the operator uses internal or external limits.
- Inspect related chain, shaft, and switch hardware.
- Do not confuse this with a main drive sprocket.
Important Ordering Warnings
Similar-looking Apollo sprockets may have different tooth count, bore, or limit function and may not interchange.
Professional Advisory
Gate operator parts should be matched by the operator model, part number, voltage, connector style, and installed accessory layout. For electrical diagnosis, safety-device issues, or unsafe gate movement, use a qualified gate technician. Do not bypass required safety devices to make an operator run.
Product Questions and Answers
Is 25B24 the main drive sprocket?
No. It is a limit sprocket quick-release component, not the main slide gate drive sprocket.
Which operators use this part?
It is commonly listed for compatible Apollo 7200 and 7300 limit assemblies where 25B24 is specified.
Can I order it by sprocket size alone?
No. Match the operator model, limit assembly style, shaft size, and original part number.
What symptoms point to a worn limit sprocket?
Inconsistent stopping, slipping, damaged teeth, loose sprocket fit, or unreliable limit travel can point to a worn limit assembly part.
Are all Apollo 7200 and 7300 limit parts the same?
No. Generation and limit style matter, so the parts diagram should be checked.
