GQZ RNA4906 Needle Roller Bearing 35×47×17mm Without Inner Ring Single Row Needle Bearing For Compact Machinery

The RNA4906 single row needle roller bearing has no inner ring, adopting cage-guided needle rollers to achieve high radial load capacity within slim radial space. The shaft directly serves as the raceway and needs surface quenching and grinding.

It is widely used in compact transmission machinery with limited installation space and medium-low speed operation.

• No inner ring design minimizes radial height, saves mounting space for compact structures
• High density needle rollers offer outstanding radial load capacity under limited dimension
• Cage separates needles to avoid friction and ensure stable medium & low speed rotation
• Suitable for integrated structure where shaft can be hardened and ground as raceway
• Can be matched with separable inner ring IR30×35×17 to convert into NA4906
• Custom design available (contact seals, special lubricant, OEM laser marking)
