AV20 AV25 AV Series One Way Roller Bearing Backstop

AV Series One Way Roller Type Backstop Clutch Bearing

Production introduction

Structure: AV is a roller type freewheel. It is self-contained, centered by plain bearings for low rotational speeds, and sealed using shield protected metallic labyrinth seals.

Application: Primarily used as backstop, working environments is high humidity like fishery machinery .

Package detail: radial spherical plain bearings are delivered grease lubricated, ready to install in a vertical or horizontal position.

• Compact, highly reliable and fully self-contained design.
• 9 frame sizes covering a shaft diameter range of 68-411mm.
• Normal, large and extra large shaft variants for each frame size allowing the optimum sized bearing to be selected for the application.
• Available with single (downward) thrust pads and upper thrust capability via tilting upper thrust pads or a whitemetal location face.
• Design includes offset pivoted tilting thrust pads in order to reduce oil film temperatures and maximise film thicknesses.
• Centre pivoted pads can be fitted when continuous bi-directional operation is a requirement.
• High pressure oil injection can be incorporated in the thrust faces if required.
• Radial loads are supported on line pivoted whitemetal faced tilting pads.
• PTFE thrust pads can be incorporated in the lower thrust face from frame size 9 upwards to increase the downward thrust capacity and reduce the bearing frame size.
• Available with water cooling, circulating oil cooling or fan / air cooling.
• Integral cooler assemblies can be supplied in cupro-nickel, stainless steel or titanium.
• Electrical insulation can be provided.
• Sealing to various IP grades can be provided at the top or bottom of the bearing as required.
• Easy to install and maintain.
• Design can accommodate a wide variety of instrumentation requirements
