Product Description

Specification

    Needle bearings are rolling bearings with extremely small cross-sectional dimensions but extremely high load-carrying capacity. Their core feature is the use of slender needle rollers (diameter ≤5mm) instead of traditional balls, enabling larger loads in limited spaces.

Core Characteristics:

    • High load density: Large contact area between needle rollers and raceways, suitable for heavy radial loads, but virtually no axial load capacity.

    • Compact design: Extremely small outer diameter saves installation space, especially in scenarios with restricted radial dimensions (e.g., gearboxes, joint parts).

    • Low friction and high rigidity: Tightly arranged needle rollers ensure stable operation, suitable for medium-low speed and high rigidity requirements.
