ANSI B29.1 / 24-hour custom bore / 17 US plant network
Match roller chain sprockets, split-taper bushings, sheaves and conveyor chain to your shaft, tooth count and uptime window without turning a catalog lookup into a week-long project.
Yes. Share bore diameter, keyway, set screw position, hub style and chain size. The 24-hour custom bore lane is designed for standard ANSI B29.1 roller chain sprockets where a stocked blank can be finished without special heat-treat changes.
Chain pitch, roller diameter, shaft speed in rpm, center distance and driven load are enough for a first pass. For shock-loaded conveyors, we also ask for starts per hour and service factor so the recommendation does not rely on nameplate power alone.
Split sprockets are useful when removing bearings, guards or long shafts would cost more downtime than the component itself. They fit many bucket elevator, oven, washer and conveyor rebuilds where access is limited.
Yes. Sheave, V-belt and split-taper bushing questions can be reviewed together, including bore, belt section, pulley diameter, guard clearance and allowable belt speed for the drive envelope.
Washdown guards, low downtime windows and repeatable spare part IDs.
Shock load, dust and shaft access drive split component choices.
Repeatable assemblies for belt centers, sheave ratio and line speed.
Large tooth counts, bore verification and safe field replacement planning.
Martin Sprocket & Gear content here is tuned for the engineer who has a shutdown date, an old part number and a drive that needs a sensible replacement path.
Chain pitch, tooth count, hub style and bore checks kept together.
Bushing selection that respects shaft fit, keyway and removal space.
Fast finishing for stocked blanks when the specification is complete.
Quote requests ask for rpm, load and environment instead of vague notes.
"The useful part is not just finding a sprocket. It is confirming the bore, chain size and installation path before the maintenance window opens."
Maintenance Planner, multi-line material handling facility
Start with chain size, tooth count and bore. Add operating notes such as rpm, washdown, dust, shock loading or limited shaft access. A spec engineer can then route the request toward a stocked blank, finished bore, split sprocket or sheave and bushing combination.
Send the chain size, bore and operating notes. We will help narrow the practical options and documentation path.
