SKF 6309 Series Ball Bearing, 45mm Inside Diameter, 100mm Outside Diameter - 6309-Z/C5


This ball bearing is a single-row deep-groove solution designed for radial and moderate axial load applications in rotating equipment. It features steel rolling elements and protective shields to limit contamination, offering consistent rotational support where controlled internal clearance and moderate speed capability are required.

Features and Benefits:


• Shielded contact reduces ingress and simplifies maintenance
• C5 internal clearance lowers operating friction at temperature
• Sheet-metal cage ensures secure retention of rolling elements
• Dynamic capacity of 55.3 kN supports sustained operational loads
• Static capacity of 31.5 kN aids load-holding when stationary
• Limiting speed rated at 9,500 r/min for higher-speed applications

Applications


• Suitable for conveyor drive shafts in manufacturing lines
• Ideal for electric motor spindle support at moderate speeds
• Used with gearbox shafts requiring axial and radial support
• Can be used for pump and compressor bearing locations
• Suitable for industrial fans and blower rotor assemblies

What bore configuration does it use for shaft mounting?


It employs a cylindrical bore allowing straightforward press or slip fit on standard shafts.

How does the cage material affect performance?


The sheet-metal cage provides dimensional stability and keeps rolling elements evenly spaced under varying loads.

What clearance class influences thermal growth and preload?


The C5 internal clearance offers additional radial play to accommodate thermal expansion in tight assemblies.

How does the shielded end type impact lubrication retention?


Shields help retain grease within the bearing while restricting larger particle ingress, extending lubrication intervals.

What is the bearing's race width and outside diameter specification?


The race width is 25 mm and the outside diameter measures 100 mm.
