SMR95 2rs Bearing Product Overview & Core Advantages
The SMR95 2RS is a metric single row deep groove ball bearing engineered for precision applications requiring reliable performance in compact spaces. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantage lies in the integrated rubber seals (2RS) on both sides, which effectively retain lubrication and exclude contaminants, making it a robust, maintenance-free solution. This bearing is designed to handle primarily radial loads and is characterized by its low friction, quiet operation, and long service life, making it ideal for high-reliability applications.
SMR95 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| SMR95 | Standard bearing designation indicating a 5mm bore, 9mm OD, and 3mm width. | Defines the compact bearing dimensions for design integration. |
| 2RS | Contact rubber seals on both sides of the bearing. | Provides superior protection against contamination and grease leakage, enabling a maintenance-free design. |
SMR95 2rs Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The use of stainless steel for all critical components (rings, balls, cage) ensures superior corrosion resistance and suitability for harsh environments, enhancing the bearing's longevity.
- Deep Groove Raceway & High-Quality Balls: The deep groove geometry and eight precision-ground stainless steel balls enable efficient handling of radial dynamic loads (74 lbf) and moderate axial loads in both directions.
- Integrated Rubber Seals (2RS): These contact seals are the primary feature, creating an effective barrier that retains the factory-applied lubricant and excludes dust, moisture, and other particulates. This is critical for achieving the specified limiting speed of 45,000 rpm and a long, maintenance-free operational life.
- Precision Manufacturing (ABEC1): Manufactured to ABEC1 tolerance class, this bearing provides reliable running accuracy for a wide range of precision applications, ensuring smooth and consistent performance.
SMR95 2rs Bearing Typical Application Areas
The SMR95 2RS is ideally suited for small, high-speed, and precision mechanisms across various industries. Common applications include:
- Small Electric Motors: Used in miniature DC motors, stepper motors, and fans.
- Precision Instruments: Found in optical encoders, medical devices, and laboratory equipment.
- Office Automation & IT Equipment: Applicable in small printers, scanners, and disk drives.
- Radio Control Models & Robotics: Supports high-speed shafts in drones, servos, and small robotic joints.
