12306 IJK Miniature Self Aligning Ball Bearing 6x15x5

12306 IJK Miniature Self Aligning Ball Bearing 6x15x5

12306 IJK is a miniature double row self aligning ball bearing designed for compact rotating systems requiring shaft misalignment compensation together with stable high speed operation and reduced installation space.

Self aligning ball bearings differ from standard deep groove ball bearings due to their ability to compensate for minor shaft and housing misalignment during operation. The double row ball arrangement combined with a spherical outer raceway enables:

• compensation of shaft misalignment
• reduction of mounting stresses
• stable operation under shaft deflection
• minimized edge loading on rolling elements

The 12306 IJK model belongs to the category of miniature self aligning bearings used in:

• precision mechanics
• miniature electric motors
• industrial automation systems
• lightweight transmission assemblies
• measuring equipment
• guiding systems
• laboratory devices

The compact dimensions 6x15x5 mm allow installation in miniature mechanical systems requiring low rolling resistance and accurate shaft guidance.

The 12306 IJK bearing is equipped with C3 internal clearance. The C3 designation indicates:

• increased radial internal clearance
• compensation capability for thermal expansion
• improved operating stability at elevated temperature
• better suitability for high speed rotation

C3 clearance is commonly used in miniature applications operating:

• at elevated rotational speed
• under variable temperature conditions
• during continuous operating cycles

The bearing uses a steel cage providing:

• stable ball guidance
• low friction characteristics
• resistance to dynamic loading
• good dimensional stability

The open bearing construction without seals allows:

• operation at high rotational speed
• effective oil lubrication
• minimized rolling resistance

The phrase 12306 IJK 6x15x5 miniature self aligning ball bearing C3 is frequently searched in servicing applications involving precision mechanical systems and compact rotating equipment.

Construction and operating characteristics
