SMF85zz Bearing Product Overview & Core Advantages
The SMF85zz is a miniature single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle radial loads efficiently, a shielded design for contaminant protection, and compliance with ABEC1 precision tolerances, making it ideal for high-reliability, space-constrained environments.
Model Code In-Depth Analysis
- SMF85: Denotes the bearing series and size (8mm OD, 5mm Bore).
- zz: Indicates that the bearing is shielded on both sides (2Z). This provides protection against solid contaminants while allowing for high-speed operation.
SMF85zz Bearing Structural Features & Performance Benefits
Compact & Lightweight Design: With a width of just 2.5 mm and a weight of 0.42 g, this bearing is optimized for miniature assemblies and portable devices.
High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 47,700 rpm, suitable for demanding rotary applications.
Corrosion Resistance: All components, including rings, balls, cage, and shields, are made from stainless steel, ensuring long-term performance in harsh or washdown environments.
Precision Performance: Manufactured to ABEC1 tolerance class and featuring a controlled MC3 radial internal clearance, this bearing provides smooth, quiet, and precise operation.
SMF85zz Bearing Typical Application Areas
The SMF85zz is ideally suited for a wide range of compact and precision devices, including:
- Small Precision Motors (e.g., drone motors, miniature DC motors)
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Measurement Devices
- Robotics and RC Models
