Overview
The Consolidated N-408M roller bearing is a precision-engineered cylindrical roller bearing built for demanding industrial applications. This bearing combines reliable radial load capacity with the durability needed for continuous-duty machinery. The “M” cage designation indicates a machined bronze cage construction, providing superior performance over stamped steel alternatives.
Key Features
- Cylindrical roller design optimized for high radial load capacity
- Machined bronze cage (M suffix) for extended service life and stability
- Single-row configuration suitable for floating bearing applications
- Separable inner ring for simplified installation and maintenance
- Available in multiple internal clearance options (C/2, C/3, C/4, W/23, C/5)
Technical Specifications
- Bore Diameter: 40 mm
- Outside Diameter: 110 mm
- Width: 27 mm
- Bearing Type: Cylindrical Roller, Single Row
- Cage Material: Machined Bronze
- Load Type: Radial
