SKF Angular Contact Ball Bearing, 45mm Inside Diameter, 85mm Outside Diameter - 3209 A-2ZTN9/MT33


This angular contact ball bearing is a robust and versatile solution for a variety of mechanical applications. Designed as a double row steel ball bearing, it features an inside diameter of 45mm and an outside diameter of 85mm, making it suitable for use in demanding environments. The unique design offers enhanced load-carrying capabilities and is shielded on both sides to prevent contamination.

Features & Benefits


• Designed with a high dynamic load capacity of 52 kN
• Offers a static load rating of 41.5 kN for durability
• Both sides shielded to protect against debris ingress
• Constructed from steel materials for increased longevity
• Non-metallic cage allows for smoother operation

Applications


• Ideal for machinery requiring high-performance bearings
• Used in automotive for smooth operation
• Effective in industrial automation setups for precision
• Suitable for electrical components needing effective load management
• Can be found in various mechanical gears and assemblies

What are the advantages of using this design in high-load applications?


The double row configuration allows for superior load distribution, enhancing reliability under high-stress conditions. This architecture also enables it to withstand axial and radial forces, making it ideal for demanding settings.

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


The shielded design on both sides prevents contaminants from entering the bearing, thereby reducing wear and prolonging service life. This feature is particularly beneficial in environments where exposure to dirt and moisture is a concern.

What maintenance requirements should be considered for optimal performance?


Regular inspections and proper lubrication are essential to ensure the bearing operates smoothly. Adequate lubrication helps minimise friction and extends the bearing life, especially at the indicated operational speeds.

How does the cage material impact operational efficiency?


The non-metallic cage significantly reduces friction within the assembly, facilitating smoother operation and minimising energy loss, which is critical in high-speed applications.

What would be the implications of exceeding the bearing speed limit?


Operating beyond the specified limiting speed of 7500 r/min may result in overheating and premature failure due to excessive wear. This can lead to reduced efficiency and increased downtime for repairs or replacements.
