Need Bearing

Needle bearings are a type of roller bearing with long, thin cylindrical rollers resembling needles. They are used in applications where space is limited and high load capacity is required.

• Basic Function: To support radial loads in compact spaces with high load capacity.
• Operation: The needle rollers are arranged parallel to the axis of the shaft, allowing them to roll freely between the inner and outer raceways.
• Maintenance: Regular lubrication is crucial to prevent wear and overheating. Inspection for roller alignment and cage integrity is also important.
• Failure Modes: Common failure modes include roller skewing, wear, and cage failure. Contamination and insufficient lubrication can also cause premature failure.
