The MF105 ZZ bearing is designed for micro-sized equipment with stringent space and precision requirements. It is widely used in precision instruments, miniature motors, office automation equipment, medical devices, robotic joint modules, optical focusing systems, and consumer electronics (such as drones and hard drive spindles). Its miniaturization and high reliability meet the critical demands of high-tech industries for precision transmission components.
Product structure:
This bearing is a standard miniature deep groove ball bearing with a 5mm bore, 10mm outer diameter, and 4mm width. It features an open-type stamped steel cage and bilateral metal shields (ZZ-type sealing). The compact structure with integrated raceways on inner and outer rings ensures stable load-bearing and smooth operation. The metal shields effectively prevent dust ingress while reducing lubricant leakage.
Key performance features:
High-Speed Capability: Optimized internal geometry and fine finishing suit high-speed rotation scenarios.
Low Noise and Vibration: Precision balls and raceway matching ensure smooth and quiet operation.
Dust Protection: Metal shields provide basic protection, extending service life in clean to moderately contaminated environments.
Light Load and High Precision: Suitable for light-load precision positioning, with small radial clearance and controllable axial displacement.
Cost-Effective: Standardized miniature bearing with high cost-performance ratio, easy to procure and replace.
Main application scenarios:
Miniature Motors: Spindle support for DC motors, stepper motors, cooling fan motors, etc.
Precision Instruments: Transmission components in measuring instruments, analytical equipment, and clock movements.
Office Equipment: Rollers and drive shafts in printers, scanners, and copiers.
Consumer Electronics: Gimbal mechanisms in drones, camera focusing mechanisms, and gearboxes in model cars.
Medical Devices: Small rotating units in dental tools, infusion pumps, and portable monitors.
Technical Specifications and Requirements:
Material Standards: Bearing steel (GCr15/SAE52100), low-carbon steel cage, chrome steel balls.
Precision Class: Typically conforms to ABEC1 or ABEC3 (P0 or P6 grade), higher precision available upon request.
Lubrication: Pre-lubricated with general-purpose lithium grease; synthetic oils or dry lubricants can be applied as needed.
Operating Temperature: Suitable for -30°C to +120°C under standard lubrication; special lubrication required for high-temperature environments.
Load Capacity: Dynamic load approximately 1.2kN, static load approximately 0.5kN (refer to manufacturer manual for details).
Installation Requirements: Ensure proper tolerance fit between shaft and housing (recommended shaft h5, housing H6) to avoid deformation from excessive interference.
