| Outside Diameter | 366 mm |
| Width | 13 mm |
Product Description

KDN.K34013AR0 Thin Section Bearing
Four-point contact ball bearing with integral seals or shields, engineered for applications that demand maximum space and weight savings. The constant cross section across the bore range allows significant design flexibility with a single bearing type.
Key Features
- Accommodates radial, axial and moment loads simultaneously
- Requires significantly less axial space than double row angular contact ball bearings
- Integrated seals extend bearing service life
- Thin cross section, light weight, low friction
- High stiffness and high running accuracy
Applications
Robotics, semiconductor manufacturing equipment, medical devices, machine tools, aerospace, rotary tables and index drives.
Supply Capability
- Factory direct supply with strict quality control
- OEM / ODM customization available
- Equivalent to Kaydon / SKF KDN series
- Stable lead time and after-sales support
