Introduction
RNA, NK Needle roller bearings are bearings without inner rings.
It mainly used on automobiles, machinery tool, printing machinery, textile machinery, Motor, Machinery, Electric Tools, Sports Apparatus, office equipment , Scooter Aluminum windows , shower blocks, hanging round, closet wheel, etc.
The mounting position is accurately determined by the support ring.
Other components on the shaft can be positioned axially against the bearing and adapter sleeve via spacer sleeves.
The arrangement is easier to dismount than when a smooth shaft is used as the bearing inner ring abuts the support ring.
Bearing clearance can be adjusted, within certain limits, to the operating conditions during mounting.
Support of shaft ends.
Bearing arrangements which have to be repeatedly mounted and dismounted.
