Are angular contact bearings directional ?
Angular contact (Spindle) bearings are designed to withstand axial loads in only one direction. The “V” laser marking on the outer ring denotes the direction of load applied to the bearing outer ring.
Do angular contact bearings need preload?
Preload for Angular Contact Bearings
First, it's important to know that a preload is required for angular contact bearings. This is because of the bearing design; it needs constant contact to happen between the balls and raceway. This constant contact is achieved through a bearing preload.
