305-2Z Bearing Product Overview & Core Advantages
The 305-2Z is a single row deep groove ball bearing featuring integral shielded protection on both sides. Engineered for high reliability and long service life in demanding applications, it is pre-lubricated with grease and ready for immediate installation. Its fundamental design excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. With a P0 tolerance class and standard CN radial internal clearance, it offers a robust and cost-effective solution for a wide range of industrial machinery, ensuring smooth operation and reduced maintenance requirements.
305-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 305 | Standard bearing series designation, defining the bearing dimensions (25mm bore, 62mm OD, 17mm width). | Ensures interchangeability and easy sourcing. |
| 2Z | Bearing is equipped with shielded seals on both sides. | Provides effective protection against contamination while allowing for high-speed operation compared to contact seals. |
305-2Z Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: The optimized raceway geometry facilitates smooth rotation and is capable of supporting significant radial dynamic load ratings (5148 lbf) and radial static load ratings (3507 lbf).
- Shielded Protection (2Z): The non-contact steel shields retain the factory-applied grease lubrication and effectively exclude larger particulate contaminants, enhancing bearing life and enabling a limiting speed of 10,400 rpm.
- Nylon Cage: The lightweight and robust Nylon cage ensures precise ball guidance, reduces friction, and is well-suited for high-speed applications, contributing to quieter operation and lower operating temperatures.
- Pre-lubricated & Ready-to-Use: Filled with high-quality grease, the bearing is lubricated for life in many applications, reducing initial setup time and maintenance needs within its specified temperature range of -30°C to 120°C.
305-2Z Bearing Typical Application Areas
This versatile shielded bearing is ideally suited for a multitude of applications across various industries, including:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
- General Industrial Machinery requiring reliable, maintenance-free operation.
