Overview
The Dodge NSTU-SCM-107 (part number 135105) is a precision setscrew take-up ball bearing designed for shaft alignment and power transmission systems. This 208 series medium-duty narrow-slot bearing accommodates a 1-7/16 inch bore with a dynamic load capacity of 7332 lbf and static load capacity of 4475 lbf. The bearing features a single-lip contact seal and operates at speeds up to 3500 rpm, making it suitable for industrial machinery requiring stable, low-maintenance operation.
Key Features
- Premium setscrew mounted design with 65-degree set screw angle for optimized shaft holding power without excessive inner ring distortion
- Cast iron housing construction with solid design and non-expansion (fixed) configuration
- Narrow-slot take-up housing type compatible with NS-400 take-up frames
- Greasable design using Unirex N2 lubricant for extended service intervals
- Single-lip contact seal provides effective protection in general industrial environments
- American-manufactured steel insert with powder-coated finish for corrosion resistance
