SMR106 Bearing Product Overview & Core Advantages
The SMR106 is a metric miniature ball bearing designed for applications demanding compact size and reliable performance. As a single row deep groove ball bearing, it excels at handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for various industrial environments. Its compact dimensions (6mm bore, 10mm OD, 2.5mm width) and light weight (0.55g) make it an ideal choice for space-constrained, high-precision assemblies requiring smooth operation.
SMR106 Bearing Model Code Explained, Specifications & Naming Convention
- SMR: Manufacturer series designation for miniature stainless steel bearings.
- 1: Indicates the specific cross-section series.
- 06: Specifies the bore diameter of 6 mm.
Key implied specifications from this model include an open (unsealed) design, requiring external lubrication, and construction from stainless steel for enhanced durability.
SMR106 Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and stainless steel cage provide stable operation and effective radial load capacity (86 lbf dynamic, 35 lbf static).
- High-Speed Capability: With a limiting speed of 40,500 rpm, it is engineered for high-speed applications.
- Precision Engineering: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 / 0.002mm to 0.013mm), ensuring consistent performance and low vibration.
- Corrosion Resistance: All components (rings, balls, cage) are stainless steel, offering protection in harsh or washdown environments and complying with ROHS and REACH standards.
- Optimized Ball Complement: Features 10 balls of 1.2mm diameter, balancing load distribution and rotational smoothness.
SMR106 Bearing Typical Application Areas
- Small Precision Motors and stepper motors.
- Medical Devices and dental handpieces.
- Office Automation Equipment such as printers and scanners.
- Instrumentation and precision measuring devices.
- Radio Control Models and small drones.
