6932Z 3x8x4mm Shielded, Ultra-Compact for Micro Motors & Precision Instruments Miniature Ball Bearing

Compact Footprint, Big Capability
At just 3x8x4mm, the 6932Z packs a true deep-groove raceway into one of the smallest standard bore sizes on the market, making it a natural fit wherever panel space and shaft diameter are both tightly constrained.

Built for Micro-Precision Motion
Engineered for micro motors, laser-level rotating heads, and robotic finger-joint mechanisms, it keeps rotational play low while handling the light, high-speed duty cycles typical of miniature actuators and sensor gimbals.

Double-Shielded Protection
Metal shields on both sides keep out dust and fine debris without the drag of a rubbing seal, so starting torque stays low - a key spec for coin-cell or micro-motor-powered devices.

Consistent, OEM-Ready Quality
Every batch is checked for radial clearance, runout, and shield seating before packing, giving buyers a drop-in component for high-volume miniature-device assembly lines without extra incoming inspection.

Sourcing Confidence
Sample pieces, dimensional inspection reports, and packaging options for both bulk reels and tray packs are available on request, helping micro-motor and instrument OEMs move quickly from evaluation to purchase order.
