SMF115 2rs Bearing Product Overview & Core Advantages
The SMF115 2RS is a metric miniature ball bearing engineered for precision applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing with integral rubber seals (2RS), it is optimally designed to handle radial loads efficiently. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its compact design, with a 5mm bore and 11mm outer diameter, makes it an ideal solution for applications where space is limited and high reliability is paramount.
Model Code Breakdown
- SMF115: Denotes the bearing series and size designation (5mm bore, 11mm OD).
- 2RS: Indicates the bearing is fitted with two rubber contact seals on both sides. These seals provide superior protection against contaminants and retain lubricant effectively.
SMF115 2rs Bearing Structural Features & Performance Benefits
Robust Construction: The stainless steel rings, balls, and cage ensure high corrosion resistance and durability in demanding environments.
Effective Sealing: The 2RS rubber contact seals provide excellent defense against dust, moisture, and other contaminants, significantly extending the bearing's service life and making it suitable for a wide operating temperature range from -30°C to 110°C.
Radial Load Capacity: The deep groove raceway and 8-ball design are optimized for carrying radial dynamic loads up to 123 lbf and static loads up to 46 lbf.
Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), this bearing ensures smooth and consistent operation.
SMF115 2rs Bearing Typical Application Areas
The SMF115 2RS is widely used in various compact and precision mechanisms, including:
- Small Electric Motors (e.g., drones, RC models)
- Precision Instruments and medical devices
- Office Automation Equipment (printers, scanners)
- Low-Power Gearboxes and small machinery
