Installing a rotating table bearing, also known as a turntable bearing or slewing ring, requires precision and adherence to specific steps to ensure proper functionality and longevity.
Rotary Table Bearing Installation Guide
Preparation
Read the Manual: Always refer to the manufacturer’s manual for specific instructions and specifications for the bearing.
Clean the Surfaces: Ensure that the mounting surfaces of both the rotating table and the bearing are clean, flat, and free of debris.
Inspect the Bearing: Check the bearing for any damage or defects. Ensure that it is the correct type and size for your application.
Installation Steps
Positioning the Bearing:
Place the bearing on the mounting surface. Align it with the pre-drilled holes in the structure.
Some bearings have a fixed-point mark or a load plug that should be positioned as recommended by the manufacturer (e.g., in the direction of the main load).
Bolt Installation:
Insert bolts in a star pattern to ensure even pressure distribution.
Tighten the bolts loosely at first to keep the bearing in place.
Tightening the Bolts:
Use a calibrated torque wrench to tighten the bolts in the star pattern to the manufacturer’s specified torque.
Gradually increase the torque in steps until all bolts are tightened to the final specified torque.
Re-check the torque after the initial tightening to ensure even distribution.
Lubrication:
Lubricate the bearing according to the manufacturer’s recommendations. This usually involves applying grease through designated grease fittings.
Rotate the bearing slowly while applying grease to ensure even distribution.
Final Checks:
Rotate the bearing manually to ensure smooth operation and that there is no binding or unusual resistance.
Re-check all bolts for proper torque.
Inspect for any misalignment or uneven gaps between the bearing and the mounting surface.
Maintenance Tips
Regular Lubrication: Follow a regular lubrication schedule as recommended by the manufacturer to ensure smooth operation and longevity.
Periodic Inspections: Regularly check for signs of wear, excessive play, or unusual noises.
