1203J Bearing Product Overview & Core Advantages
The 1203J is a double row deep groove ball bearing designed for applications requiring high radial load capacity and compact design. This metric bearing features an open construction, allowing for versatile lubrication options and easy maintenance. Its primary advantages include a high radial dynamic load rating of 1989 lbf, enabling reliable performance under significant stress. Manufactured from high-grade chrome steel, it ensures durability and long service life, making it an ideal choice for demanding industrial environments where precision and reliability are paramount.
1203J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1203 | Standard designation for a double row deep groove ball bearing with a 17mm bore diameter. |
| J | Indicates a specific internal design, typically relating to the radial internal clearance group. In this case, it corresponds to the CN (Normal) clearance group. |
1203J Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The double row ball bearing construction provides superior radial load carrying capacity and enhanced rigidity compared to single row designs, offering stable support for rotating shafts.
- Optimized Internal Geometry: Precision-engineered raceways and chrome steel balls ensure smooth operation and minimize friction, contributing to the high limiting speed of 24,000 rpm.
- Steel Cage: The robust steel cage accurately spaces and retains the balls, ensuring reliable performance at high speeds and under varying load conditions.
- Standard Radial Clearance: The CN clearance is suitable for a wide range of general industrial applications, providing an optimal balance between operational temperature rise and running precision.
- Broad Temperature Range: Operates effectively within a temperature range of -30°C to 110°C, ensuring performance stability in diverse operating environments.
