SMF93zz Bearing Product Overview & Core Advantages
The SMF93zz is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. Constructed as a single row, shielded bearing, it is engineered to handle primarily radial loads in demanding environments. Its all-stainless steel construction provides excellent corrosion resistance, making it suitable for applications where contamination must be minimized. The bearing offers a high limiting speed and is supplied with a standard MC3 radial clearance, ensuring smooth operation and long service life in precision instruments and small machinery.
SMF93zz Bearing Model Code Explained, Specifications & Naming Convention
- SMF93: Denotes the bearing series and size designation (3mm bore, 9mm OD).
- zz: Indicates that the bearing is shielded on both sides (2Z). This provides effective protection against contaminant ingress while minimizing friction, contributing to the high limiting speed.
SMF93zz Bearing Structural Features & Performance Benefits
Compact & Robust Design: With a bore diameter of 3 mm and width of 4 mm, this bearing offers a space-saving solution without compromising strength. The stainless steel cage and components ensure dimensional stability and resistance to corrosion.
High-Speed Capability: The optimized design, including the 6 precision balls and low-friction shields, enables a limiting speed of 50,400 rpm, making it suitable for high-speed spindles and miniature motors.
Reliable Load Handling: With a dynamic load rating of 98 lbf and static load rating of 31 lbf, it provides dependable performance under radial stresses in compact assemblies.
