Product Overview: The 1305 Self-Aligning Ball Bearing
The 1305 bearing is a high-capacity self-aligning ball bearing with principal dimensions of a 25mm bore diameter, 62mm outer diameter, and 17mm thickness. As a key component in our 1300 Series, this bearing is engineered to perform reliably in applications prone to shaft deflection or mounting inaccuracies. The design features a spherical outer ring raceway and two rows of balls, which allows the inner ring, balls, and cage to freely align with the outer ring. This intrinsic self-aligning capability prevents excessive stress on the bearing, significantly extending its operational life.
Built to handle heavier radial loads and moderate axial loads in both directions, the 1305 is an excellent choice for demanding industrial environments. It's a fundamental part of our broader Self-Aligning Ball Bearings collection, trusted by industries for its durability and performance under challenging conditions. For applications requiring mounting on tapered shafts or using adapter sleeves, a tapered bore version (1305K) is also commonly available.
Features of the 1305 Bearing
- Self-Aligning Design: Automatically compensates for angular misalignment between the shaft and housing, ensuring smooth operation.
- Dual Row Construction: Two rows of balls provide a higher radial load capacity compared to single-row bearings.
- Robust Performance: Designed to withstand heavy radial loads and moderate thrust loads in either direction.
- Low Friction: The optimized internal geometry minimizes friction and heat generation, leading to greater efficiency and a longer service life.
- Durable Material: Manufactured from high-quality bearing steel for superior hardness, wear resistance, and fatigue life.
- Mounting Versatility: Available with a cylindrical bore for direct shaft mounting or a tapered bore for use with adapter sleeves like the H 206.
Applications of 1305 Bearings
- Agricultural Machinery: Ideal for equipment such as combines, balers, and tillers where shafts are long and subject to flexing.
- Conveyor Systems: Used in rollers and drives where structural distortion can cause misalignment.
- Industrial Fans and Blowers: Accommodates shaft deflection common in large-scale ventilation systems, reducing vibration and noise.
- Mining and Construction Equipment: Provides reliable support in crushers, screening equipment, and mixers operating in harsh conditions.
- Textile and Printing Machinery: Ensures consistent performance of rollers and shafts where precise alignment is difficult to maintain.
- Pulp and Paper Mills: Withstands the demanding environments of processing machinery, including felting rollers and drying cylinders.
Benefits of Using the 1305 Bearing
- Increased Machine Uptime: The ability to handle misalignment reduces the risk of premature bearing failure and costly downtime.
- Reduced Maintenance Requirements: Its robust design and self-aligning nature lead to a longer service interval, lowering maintenance costs.
- Enhanced Operational Reliability: Provides stable and consistent performance even when shaft deflection or mounting errors occur.
- Simplified Assembly: The self-aligning feature can simplify the initial mounting process, saving time and labor.
- Lower Operating Temperatures: Operates with less friction than other bearing types under misalignment, preventing overheating.
- Versatility: Suitable for a wide range of industrial applications, making it a valuable and flexible component.
