HK 0808 KG 8x12x8 Needle Roller Bearing Without Inner Ring

Compact HK 0808 KG Needle Roller Bearing for Limited Installation Space

The HK 0808 KG 8x12x8 needle roller bearing is designed for applications requiring high load capacity within extremely compact installation dimensions. Its inner ring free construction allows direct mounting on a properly prepared shaft, reducing overall system size while maintaining efficient radial load support.

The HK series belongs to the family of thin walled needle roller bearings widely used in gearboxes, automation systems, lightweight drive assemblies, power tools and industrial machinery requiring compact dimensions and high durability. KG bearings are recognized for high radial load capacity, low operating resistance and reliable industrial performance.

Bearing Construction and Design

The HK 0808 KG bearing features a thin walled needle roller bearing construction without an inner ring and with a cage guiding the rolling elements.

Main construction features:

• inner diameter: 8 mm
• outer diameter: 12 mm
• width: 8 mm
• needle roller construction
• without inner ring
• thin walled outer shell
• high radial load capacity
• compact dimensions
• steel cage

The absence of an inner ring allows direct operation on a shaft with appropriate hardness and machining accuracy.
