695, 695Z, 695ZZ, 695RS, 695-2RS Miniature Ball Bearings 5x13x4mm – Compact Deep Groove Bearings for High-Speed Precision & Micro-Mechanical Systems

High-precision 695 series miniature deep groove ball bearings in size 5mm (ID) × 13mm (OD) × 4mm (W), engineered for compact devices and micro-mechanical systems requiring smooth, quiet, and high-speed rotation under light radial loads. Available in multiple sealing options to suit various operating environments:

• 695: Open type – ideal for clean or controlled settings with custom lubrication
• 695Z / 695ZZ (695-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 695RS / 695-2RS: Single or double rubber seals – offer superior resistance to moisture and fine contaminants

Made from high-quality chrome steel (GCr15) — with stainless steel available on request — these miniature bearings feature precision-ground raceways for low friction, minimal vibration, and reliable performance at high RPMs. Commonly used in small DC/BLDC motors, drones, RC vehicles, medical instruments, robotics, 3D printers, scanners, smart locks, and wearable tech.

Most sealed variants are pre-lubricated with low-torque, long-life grease for maintenance-free operation. The 695 series supports both radial and limited axial loads, making it an excellent choice for space-constrained, high-efficiency designs.
