AI Technical Summary
Traditional cylindrical roller bearings are prone to cage fatigue fracture under unidirectional axial loads. Uneven stress distribution leads to decreased structural stability, accelerated wear, and insufficient lubrication, resulting in premature failure.
A reinforced cage bearing is designed with an inner flange on one side and outer flanges on both sides. The rigidity is enhanced by thickening the skeleton and reinforcing beams, and oil reservoirs are set on the reinforcing beams to improve lubrication performance and prevent rollers from detaching and rubbing against each other.
It improves the bearing's load-bearing capacity and limiting speed, reduces the probability of cage breakage, extends the time the lubricating oil stays inside the bearing, and enhances lubrication performance and structural stability.
