Friction Moment – Zerk Installation
Before installation, please note the following: Silverthin slewing rings are lubricated with a minimal amount of lithium-based high-pressure grease to protect them in transit. A proper grease and fill amount should be determined for the specific application the bearing is intended for before installation.
Your slewing ring may be shipped with the grease zerks uninstalled. Those zerks will be included with your shipment and will need to be installed before installation into the application. Typically, you will only find that the zerks on the outer faces of the bearings will need to be installed; this is to protect them from damage during shipment and storage.
To install, screw the provided zerks into the predrilled and tapped lubrication holes clockwise until finger tight, then using the appropriately sized wrench, tighten the zerk a quarter turn clockwise.
If you have any questions or concern about the zerk installation, please feel free to contact us at firstname.lastname@example.org or toll fee at (866)-294-5841.
