SPHERICAL BEARING INSTALLATION
Service & Maintenance
1. Support and secure beater. Ensure the beater assembly is in the correct position - timing marks rotated
180° opposite to the second beater’s timing marks.
2.
IMPORTANT:
Check the position of the snap rings in the assembled bearing unit. They should be
located in the “fixed” position (See fig.1). On occasion they have may been sent in the default
“floating” position from the supplier but must be relocated to the ”fixed” position before installation.
Note:
Appropriate eye protection should be worn when handling snap rings.
3. Loosen the locknut almost all the way, with the exception of a few threads to keep it on the sleeve.
4. Push the locknut/sleeve firmly inward against the bearing and hold. While holding, slide the assembly
onto the shaft until the bearing housing is in position against the frame (holding the locknut is
important so the sleeve doesn’t tighten between the bearing and the shaft while sliding into position).
5. Install the bearing mounting hardware loosely then tighten mounting hardware.
6. Hand tighten the locknut and ensure adapter sleeve no longer rotates.
7. Tighten the locknut 1/3 of a rotation or 120º. A hook spanner or a hammer and punch are
commonly used. Torque to 140 lb.ft (190 N.m) if possible.
8. Bend one of the tabs on the circumference of the lockwasher into the nearest notch on the rim of the
locknut. If no tabs line up, tighten the locknut slightly. The locknut should not be loosened in order to
align the tab with a notch.
Bearings come pre-lubricated with Shell Alvania #3 and require no lubrication upon initial
installation.
9. After final assembly of machine, spin beaters to ensure they spin freely.
Note:
Do NOT grease spherical bearings - even if grease fitting is present.
REMOVAL INSTRUCTIONS
1. Support and secure beater.
2. To remove the bearing unit from the shaft, raise the bent lockwasher tab, loosen the locknut two or three turns, then
tap the nut over its entire circumference with a hammer and punch. Ensure sufficient threads remain engaged as to not
damage them. Continue tapping until the adapter sleeve can be moved.
3. Loosen and remove the mounting hardware. Clean outer shaft for easier removal. Slide complete bearing unit off.
3. To remove the bearing insert from the housing, remove one of the snap rings and slide the bearing out.
Appropriate eye protection should be worn when handling snap rings.
