NTN Disc Bearing
Riveted Flange Unit
Flanged disc harrow bearings units are integral assemblies specifically designed for the most severe tillage applications. Each configuration incorporates certain special dimensional attributes making the unit compatible in a variety of equipment designs. Inherent in most designs are two heavy gauge case hardened and zinc plated stampings which encapsulate the bearing with eight cold formed rivets for guaranteed integrity. Within the cavity two nitrile “O” rings are installed to exclude contaminants and provide a grease seal to ensure lubricant feeds directly into the bearing. The grease fitting is permanently retained in the stamping for easy access and maximum protection from the environment. The high performance NTN-BCA® disc bearing assembled into each unit has all the features detailed in the disc harrow bearing section.
The complete unit provides the following beneficial application characteristics:
- Dynamic Alignment
- Positive Relubrication
- Close Clearance Shroud Protects Bearing
- Circumferentially Restrained Outer Ring
- High Performance NTN-BCA® Disc Harrow Bearing
- Plated Case Hardened Stampings
- Solid Rivet Retention of Stampings
