Self Aligning Ball Bearings Double Row High Precision Bearings

Engineered for Endurance: Self Aligning Ball Bearings

The C3 self-aligning double row ball bearing series 1226–2218 offers a rugged and efficient solution for industries that demand stability and longevity. With a double-row structure, these bearings accommodate angular misalignments automatically—ideal for shaft deflection or housing misplacement. The Self Aligning Ball Bearings provides enhanced radial play, ensuring smoother operations in high-temperature or high-speed environments, making it particularly suited for demanding mechanical systems where slight shifts are inevitable.

Constructed from high-quality stainless steel, this bearing resists corrosion, reduces wear, and stands up to harsh working conditions. Its self-aligning double row ball bearing feature extends machinery life and decreases the likelihood of premature equipment failure, making it the preferred solution for technicians and engineers alike.

Broad Industrial Compatibility: Trusted by Professionals Worldwide

This self-aligning double row ball bearing  is an excellent fit for diverse applications across building material suppliers, manufacturing plants, and machinery repair shops. It performs reliably in rotating shafts, conveyor systems, and precision mechanical assemblies. With bore diameters ranging from 6mm to 75mm, it offers broad installation flexibility across a variety of machine types.

Supported by a precision range from P0 to P2, it caters to general industrial applications and high-precision systems. Whether you’re equipping new machines or upgrading old ones, this series delivers the balance of adaptability and high performance.

Protection You Can Trust: Advanced Sealing Options and ISO Certification

Sealing and lubrication are critical in maximizing bearing longevity. This series offers customizable sealing configurations—Z, ZZ, RS, 2RS, RZ, ZNR—to meet environmental demands from open machinery to enclosed, high-moisture areas. The open design option allows for easy lubrication access, while the sealed versions prevent dust, debris, and oil leakage from impacting internal components.

Lubricated with high-grade industrial oil, these bearings reduce friction, enhance performance, and minimize maintenance downtime. Plus, each bearing is ISO9001 certified, affirming its quality, safety, and adherence to international manufacturing standards.

What Is C3 Clearance and Why It Matters

In the context of industrial bearings, C3 clearance refers to a slightly greater internal clearance between the balls and the raceways. This added space is crucial in applications that involve thermal expansion, fast rotational speeds, or high radial loads. ball bearings prevent excessive friction and allow smoother movement under these conditions, enhancing bearing life and reducing the risk of overheating.

Applications in Detail

The 1226–2218 self-aligning ball bearing series is ideal for the following equipment:

• Textile machinery

• Crushers and mills

• Printing machines

• Paper manufacturing systems

• Agricultural mechanical assemblies

• Conveyor belt systems

Long-Term Maintenance Advantages

Bearings with self-aligning features require less frequent adjustments and are less susceptible to vibration-induced fatigue. Combined with oil-based lubrication and correct sealing, these bearings deliver long-term savings in both operational efficiency and maintenance cost.
