the x-type 4-point contact bearing is a single row ball bearing. this bearing can withstand moment loading. the x-type bearings have been created using a gothic archway. the gothic archway allows for moment and reversing axial loads to be accepted. x-type bearings are not an ideal solution for radial loads or combined radial and thrust loads.
typically the x-type 4-point contact bearing is provided with a brass cage separator and an abec 1 rating class. options abound with variations available in:
- material type for rings and rolling elements
- material thickness
- bore size
- precision class
- diametral clearance (internal fit)
applications
- antenna mounts
- bottling equipment
- blow out protectors
- converting equipment
- x-ray equipment
- food processing equipment
- gear boxes
- indexing tables
- instrument mounts
- labeling machines
- machine tools/ lathe accessories
- missile launchers
- oil well equipment
