Rack and Pinion — Bearing-supported Spur Gear (Spur gear with press-fit bearing), Compact Hubless Type (Reference CAD)

Bearing-supported spur gear: JLCMC's spur gear body, with integrated/press-fit rolling bearings (typically shown as a hubless gear with a bearing seat). It is used to transmit torque between parallel shafts while providing integrated rotational support, commonly found in compact gear sets, idler gears, and small mechanical devices, suitable for applications where gears need to rotate smoothly on pins/shafts.
