Double Row Angular Contact Ball Bearings


FAG from Schaeffler double row angular contact ball bearings are units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. They correspond in design to single row angular contact ball bearings in pairs in an O arrangement but give a narrower design. They differ in the size of their contact angle and the design of the bearing rings.

The bearings are available in open and sealed versions. Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields. Sealed bearings are maintenance free and, as a result, allow economical bearing arrangements. The self-alignment capacity of angular contact ball bearings is small.

Features and Benefits


• Lower operating costs

• Reduced maintenance due to improved lubrication

• Lower heat generation

• Less noise

Product Application Information


These bearings have improved running accuracy and optimised surfaces giving them an increase in fatigue limit load. In terms of the expanded adjusted rating life, values up to 50% are achieved. In certain applications, a smaller bearing arrangement can be designed.

Schaeffler 2 Light Series Ball Bearing, 20mm Inside Diameter, 47mm Outside Diameter - 3204-BD-XL-2HRS-TVH


This ball bearing is a double row angular contact type, suitable for various industrial applications. Featuring an inside diameter of 20mm and an outside diameter of 47mm, it is designed for effective load management. With a race width of 20.6mm, this bearing is constructed from high-quality steel, ensuring durability and reliability in demanding environments.

Features & Benefits


• Features a double row design for enhanced load capacity
• Both sides sealed to prevent contamination and wear
• Static load rating of 12.9 kN for robust performance
• Dynamic load rating of 20.6 kN supports heavy-duty applications
• Constructed with steel for longevity and resistance to deformation
• Plastic cage material reduces friction for smoother operation

Applications


• Used in automation systems to ensure precision movement
• Suitable for electrical and electronic equipment requiring reliable rotation
• Applied in mechanical assemblies where high load support is crucial
• Ideal for parallel bore in machinery and equipment

What are the advantages of using this bearing over single row types?


The dual row design significantly increases load-carrying capacity, allowing for greater stability under heavy loads. This also results in prolonged operational life due to better distribution of forces across the bearing elements.

How does the sealing arrangement contribute to the bearing’s performance?


The seals on both sides effectively protect against dust and loss of lubricants, thus minimising maintenance requirements. This enhances the overall durability and operational reliability of the bearing in challenging environments.

What materials are used in the construction of this bearing?


It features steel as the primary material, which is known for its strength and durability. The cage is made of plastic, which aids in reducing friction and wear during operation.

How does the bearing’s clearance code affect its performance?


The CN clearance code indicates a normal operating clearance, making it suitable for applications with standard thermal and load changes. This ensures optimal performance without significant risk of excessive wear or failure.

What load ratings can you expect from this model under typical conditions?


With a static load rating of 12.9 kN and a dynamic load rating of 20.6 kN, this bearing is well-suited for applications requiring consistent high loads without compromising on reliability.
