Product Overview: The 1217 Self-Aligning Ball Bearing
The 1217 bearing is a precision-engineered component from our 1200 Series of Self-Aligning Ball Bearings, featuring an 85mm bore diameter, a 150mm outer diameter, and a 28mm thickness. Its defining characteristic is the ability to accommodate both static and dynamic angular misalignment between the shaft and the housing. This is achieved through a unique internal design with two rows of balls and a common sphered raceway in the outer ring, allowing the inner ring, balls, and cage to rotate freely at an angle relative to the outer ring.
As a leading supplier of industrial components, we provide high-quality 1217 bearings that are manufactured to industry standards. These bearings are indispensable in machinery where shaft deflection or mounting errors are common, ensuring smooth, low-friction operation and preventing premature wear on the system. They are a reliable solution for a wide range of industrial applications, providing stability and longevity even under challenging operating conditions.
Features of the 1217 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment, reducing stress on the shaft and extending the life of the machinery.
- Dual-Row Design: Two rows of balls provide a higher radial load capacity compared to single-row bearings of similar size.
- Low-Friction Performance: Engineered to minimize rotational friction, resulting in lower operating temperatures and improved energy efficiency.
- High-Quality Steel Construction: Manufactured from premium-grade bearing steel for superior durability, wear resistance, and performance.
- Versatile Application Range: Suitable for various industrial environments where alignment cannot be perfectly maintained.
- Standardized Dimensions: Produced to standard ISO dimensions (85x150x28mm) for easy interchangeability and system integration.
Applications of 1217 Bearings
- Agricultural Equipment: Widely used in harvesters, tractors, and other farm machinery that operates on uneven terrain.
- Conveyor and Pulley Systems: Ideal for long shafts that may experience deflection under load, ensuring rollers remain aligned.
- Industrial Fans and Blowers: Accommodates shaft flexing to maintain smooth and quiet operation in ventilation systems.
- Textile Machinery: Ensures the reliable operation of spindles and rollers, which are prone to misalignment.
- Mining and Construction Equipment: Provides robust support in heavy-duty machinery exposed to harsh conditions and potential frame distortion.
- Food and Beverage Processing: Suitable for machinery where frequent washdowns and operational stresses can affect alignment.
- Pulp and Paper Mills: Used in rollers and processing equipment where moisture and long shaft lengths are common.
Benefits of Using the 1217 Bearing
- Increased Machine Uptime: The ability to handle misalignment reduces the likelihood of bearing failure and costly downtime.
- Reduced Maintenance Requirements: Its robust design and self-correcting nature lead to a longer service life and fewer replacements.
- Enhanced Operational Efficiency: Low friction characteristics contribute to smoother machinery performance and potential energy savings.
- Simplified Assembly: The self-aligning feature makes the mounting process more forgiving, saving time and labor.
- Improved System Reliability: By preventing edge stresses caused by misalignment, it enhances the overall durability of the mechanical system.
- Cost-Effective Solution: Offers a long-term, reliable solution that minimizes the total cost of ownership through reduced maintenance and replacement expenses.
