Drawn Cup Needle Roller Bearings
AMIGO Drawn cup needle roller bearings feature a deep drawn, thin-walled outer ring and are ideal for applications where the housing bore can’t serve as a raceway for a needle roller and cage assembly. These bearings are compact, economical, and mounted with a tight interference fit in the housing, allowing for a simple and cost-effective housing bore design without the need for shoulders or snap rings for axial location.
- Low cross section
In applications where less space is available, drawn cup needle roller bearings enable downsizing. - High load carrying capacity and stiffness
Owing to their large number of rollers, drawn cup needle roller bearings have a high load carrying capacity and stiffness. - Good running properties
Drawn cup needle roller bearings are widely used in various industries. Their availability matches their versatility across numerous applications in a wide range of designs, variants, and sizes. Examples of applications include:
- Automotive Industry
- Aerospace Industry
- Construction Equipment
- Agriculture Machinery
- Industrial Machinery
- Power Tools
Drawn Cup Needle Roller Bearings - Designs and Variants
Bearings with Open Ends
Bearings with open ends are designed for applications requiring higher speeds and smooth operation. They allow for free axial movement of the shaft within the bearing, providing greater versatility. Commonly used in systems with rotating shafts where lubrication is easily accessible.
Bearings with a Closed End
Closed-end bearings offer enhanced protection from contaminants as one end of the bearing is sealed off. These bearings are ideal for use in environments where dirt, debris, or moisture could enter and disrupt the bearing’s performance. Typically found in enclosed systems.
Full Complement Bearings with Open Ends
Full complement bearings with open ends feature the highest load-carrying capacity due to the maximized number of rolling elements. These bearings are ideal for heavy-duty applications where high load capacity is prioritized over speed, and lubrication is easily maintained.
