Designed for environments where severe contamination is present, such as agricultural tillage equipment.
One-piece Tri-Ply seals:

• Incorporate a highly effective design molded to an exterior shroud cap.
• Provide exceptionally effective protection against loss of lubricant and entrance of wet or abrasive contaminants.

Seven-piece Tri-Ply construction:

• Standard on certain sizes
• Shroud cap nests closely with the outside seal
• Helps protect the rubber seal members from fiber wrap warpage and abrasion
• Balanced design, identified by deep races, large balls and extra-wide or heavy, shock-resistant inner and outer rings.

Use of Tri-Ply Seal bearings simplifies housing designs and their extra inner ring width provides greater support on the shaft.
