SMF105 2rs Bearing Product Overview & Core Advantages
The SMF105 2RS is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) for effective contamination protection. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its primary advantages include a compact 5mm bore design, suitability for radial loads, and robust construction for high reliability in demanding miniature applications.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SMF105 | Basic bearing designation indicating a flanged miniature bearing with 5mm bore diameter, 10mm outside diameter, and 4mm width. |
| 2RS | Bearing is equipped with contact rubber seals on both sides, providing superior protection against dust and moisture ingress. |
SMF105 2rs Bearing Structural Features & Performance Benefits
- Compact & Robust Design: The single-row deep groove raceway and stainless steel construction provide a robust yet compact solution for space-constrained applications, offering excellent dimensional stability.
- Effective Sealing: The NBR rubber seals (2RS) effectively shield the internal components from contaminants, extending bearing service life and reducing maintenance needs.
- Corrosion Resistance: Manufactured entirely from stainless steel, this bearing is ideal for applications exposed to moisture, chemicals, or requiring washdown, ensuring long-term performance.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring smooth and consistent operation.
- Flange Mounting: The integrated flange (11.6mm outer diameter) simplifies mounting and positioning, providing secure axial location within a housing.
SMF105 2rs Bearing Typical Application Areas
- Precision Instruments: Optical encoders, measuring devices, and laboratory equipment.
- Small Motors & Drives: Stepper motors, miniature DC motors, and fan motors.
- Office Automation: Printers, scanners, and copiers.
- Medical Devices: Small pumps, dental handpieces, and diagnostic equipment.
- Robotics & Automation: Small robotic joints, actuators, and guidance systems.
