Engineered with metric dimensions and manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers excellent radial load capacity and consistent operation. Its shielded design provides effective contamination protection while maintaining smooth rotation. The bearing's chrome steel construction throughout all components ensures durability and long service life, making it an ideal choice for applications requiring dependable performance under standard operating conditions.
Model Code Detailed Explanation
| Code Segment | Technical Meaning | Benefit |
| 309 | Standard bearing size designation (45mm bore × 100mm OD × 25mm width) | Standardized dimensions for easy replacement and compatibility |
| S | Single shield on one side | Protects bearing interior from contaminants while allowing ventilation |
| ZZ | Shielded on both sides | Comprehensive protection against contamination from both directions |
| 1 | Radial internal clearance designation (CN group) | Standard clearance suitable for most operating conditions |
309SZZ1 Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry enables excellent radial load capacity (12,364 lbf dynamic / 9,892 lbf static) while accommodating moderate axial loads in both directions.
Shielded Protection: Double-sided steel shields provide effective contamination protection without significantly increasing rotational torque, maintaining the bearing's limiting speed of 7,500 rpm.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance standards with controlled radial internal clearance (CN group) ensures consistent performance and smooth operation.
Material Excellence: All-steel construction using chrome steel for rings, balls, and cage provides uniform thermal expansion characteristics and excellent wear resistance across the operating temperature range of -30°C to 120°C.
309SZZ1 Bearing Typical Application Areas
Electric Motors: Ideal for small to medium-sized industrial motors requiring reliable radial load support and contamination protection.
Industrial Gearboxes: Suitable for gearbox applications where standard precision and shielded protection are required.
Material Handling Equipment: Commonly used in conveyor systems, pulleys, and other material handling components.
Agricultural Machinery: Appropriate for agricultural equipment requiring durable bearings with basic sealing protection.
General Industrial Machinery: Versatile solution for various industrial applications including pumps, fans, and light machinery where standard precision bearings are specified.
