If you require any assistance in determining an applicable service factor, or would like a more detailed load rating curve (recommended if your service factor adjusted applied loads fall close to, or beyond, the load rating curves shown in this catalog), please contact Engineering for assistance. Please note that the equipment designer is responsible determining
Slewing Ring Bearings are used most commonly where rotation is slow, oscillating, and/ or intermittent. For speed limit calculations please contact Silverthin Engineering.
load capability
Slewing Ring Bearings are designed to accommodate significant radial, thrust and moment loads as shown below:
Accuracy
Slewing Ring Bearings are not typically provided with diameter tolerances. Some slewing ring applications require a higher degree of accuracy. For engineering and design support on special applications please contact our Engineering.
Typical Application“Typical application” of Slewing Ring Bearings will exhibit the conditions listed below. Special consideration must be given to bearing selection and features whenever the application conditions differ from those considered “typical”.
Those typical application conditions are:
Vertical axis of rotation. Essentially, the bearing mounted “flat”.
Compressive thrust and moment loads being predominant compared to tension loading.
Radial load limited to less than 10% of the thrust load.
For single row bearings, intermittent rotation (not continuous) should not exceed a pitch-line velocity of 500
feet/minute.
Operating temperature between -40ºF to +140ºF.
Mounting surface geometry and installation procedures to assure roundness and flatness of both races.
An example approach would be to apply a centered thrust load while tightening the bolts using the alternating.
Periodic checking of mounting bolts to verify proper tension is provided for.
Periodic lubrication is provided for.
Environment
Slewing Ring Bearings are often used indoors, and outdoors where exposure to moisture and significant contamination is possible. Normal temperature ranges -40°F to +140°F (-40°C to +60°C) are standard. Slewing rings designed to operate in harsher environments are available from Silverthin, contact a Silverthin Engineer early in your design process to identify the best bearing system solution for extreme environments.the correct service factor, often validated by testing.
