1-1/2 in 85 mm 1.18 in Round Disc Harrow Bearing

Bearings with Tri-Ply Seals are designed for service involving severe contamination, such as disk harrows, disk tillers and other seed preparation equipment and certain conveyor applications. Tri-Ply sealed units come in two designs – one consisting of three Timken rubber seals separated by steel spacers and retained by steel caps in the outer ring and the other, a highly effective one-piece, molded seal design. Both designs have an exterior shroud cap to protect the seals and reinforce the exceptional sealing action of the complete unit. A patented notched seal groove design, provided on selected sizes, is one of the most positive seal retention methods ever developed.

• Designed for environments where severe contamination is present, such as agricultural tillage equipment
• Use of Tri-Ply Seal bearings simplifes housing designs and their extra inner ring width provides greater support on the shaft
