It has come to my attention we need a guide on how to properly install and tighten the eccentric collar around the shaft bearing on the YTS rollers.
Use the following steps:
- Install the bearing in the roller end plate as shown in the photo below. Note – this photo uses a 4-hole bearing instead of a 3-hole because that’s the only 3D CAD model of a bearing I could find on the McMaster Carr website.
- Slide the eccentric collar against the mating end of the insert inner race.
- Snug the collar on the mating eccentric in the direction of shaft rotation.
- Place a mild steel bar inside the hole provided by the collar and tap the collar sharply in the direction of shaft rotation and perpendicular to the shaft.
- Tighten the set screw in the collar to the proper torque. Use Locktite to keep it from loosening up with the vibration.
- Re-check the tightness of the setscrew and hold down bolts after 24 hours of operation to ensure nothing has loosened. This check should become part of periodic maintenance including re-lube intervals.
To remove the roller bearing:
- Loosen the setscrew, then tap the collar in the direction opposite the shaft rotation.
