This gear screw is the small fixing that holds the drive gear inside a Panasonic tape feeder, and one worn screw can put a whole feeder out of service. It is a maintenance item rather than an upgrade, bought to keep existing feeders running rather than to change how they perform. PCB assembly plants, EMS companies and feeder refurbishment workshops are the usual buyers.
This screw sits within the range of spare parts we hold for the SMT pick and place machine manufacturers' platforms our customers run, so a feeder that is already in service stays serviceable.

A worn gear screw rarely fails all at once. The feeder usually starts to index unevenly first — the tape hesitates, the pick position drifts, and the machine keeps cycling while placements are missed. Technicians often notice it as a feeder that sounds different, or as repeated small stoppages on one lane rather than a single breakdown. On inspection the screw has normally worked loose, worn at the head or started to round off.
Because the part is small and inexpensive, changing it at the first sign of wear costs far less than letting it work loose and damage the gear around it. When a line stops placing SMT components reliably, this gear screw is one of the first feeder parts to check.
ZJ-SMT supplies Panasonic SMT and PCB assembly equipment and spare parts to manufacturers worldwide. Our range covers pick-and-place machines, axial and radial insertion equipment, solder paste inspection systems, and feeder spare parts, with both new and used options available. We support bulk orders, and machine condition and availability are confirmed with you before ordering. Whether you are expanding a line, replacing a worn feeder part, or sourcing equipment for a new project, send us your model numbers and our team will come back with a suitable solution and quotation.
Yes — this is bench work, so the feeder comes off the line and sits on a clean, flat surface, which keeps the small parts from rolling away while the screw is changed. Plan it for a window when that lane has no SMT components to place, and keep the feeder on a mat or in a tray while it is open.
Look at the gear teeth, the tape guide and the shaft the gear sits on. A screw that has worked loose often leaves marks on the teeth, and the small hardware around it is worth checking at the same time. Fitting a new screw against a gear that is already damaged will not restore reliable feeding.
No — NPM feeders use different hardware, and the part numbers do not interchange. Send us the machine model and the number from the old part, and we will check it against the pick and place machine manufacturers' part references we hold before you order.
It is supplied as the screw on its own, not as a complete gear assembly, which keeps a routine replacement inexpensive. In most cases the screw is the only worn item, and the gear, shaft and tape guide carry on. If your technician finds the gear or shaft has been damaged too, tell us what came off and we will identify the other items you need.
Thread size and material grade are not part of the published specification for this item, which is supplied to its part number and feeder application rather than to a generic fastener size. That is what makes matching straightforward in practice, and we are happy to confirm the right part for the machines you run.
Keep them in a dry store, separate from heavier hardware, so the threads are not knocked or crossed. Small parts are easy to mix up on a busy bench, so label the bag with the part number and the feeder it belongs to. That turns the next replacement into a two-minute job instead of a parts hunt.
