Y-bearing plummer block units with a pressed steel housing

Y-bearings with grub screws
  1. Remove any burrs on the shaft with emery cloth or a fine file, wipe clean with a cloth.
  2. Mount any components that are on the shaft between the two Y-bearing units.
  3. Slide the Y-bearings onto both shaft ends with the locking device facing outwards. Install the rubber seating ring on the outside diameter of the bearing (optional).
  4. Make sure the housing base and mating surfaces are clean and free of any debris or burrs.
  5. Position the base of each housing on its support surface.
  6. Place the shaft and Y-bearings into position in each housing base. Then, place the housing caps over the bearings (fig. 1) and fit the attachment bolts or nuts but do not tighten them.
  7. Carefully align both Y-bearing units, using the shaft. Fully tighten the attachment bolts or nuts.
  8. Align the shaft in the bearing arrangement axially and, if possible, turn it a few times.
  9. Tighten the grub screws in the inner ring of both units to the tightening torque listed in the product table.
Y-bearings with an eccentric locking collar
  1. Remove any burrs on the shaft with emery cloth or a fine file, wipe clean with a cloth.
  2. Mount any components that are on the shaft between the two Y-bearing units.
  3. With the eccentric locking collar removed, slide the Y-bearings onto both shaft ends with the locking device facing outwards. Install the rubber seating ring on the outside diameter of the bearing (optional).
  4. Make sure the housing base and mating surfaces are clean and free of any debris or burrs.
  5. Position the base of each housing on its support surface.
  6. Place the shaft and Y-bearings into position in each housing base. Then, place the housing caps over the bearings (fig. 2) and fit the attachment bolts or nuts but do not tighten them.
  7. Carefully align both Y-bearing units, using the shaft. Fully tighten the attachment bolts or nuts.
  8. Align the shaft in the bearing arrangement axially and, if possible, turn it a few times.
  9. Place the eccentric locking collar on the inner ring extension of both Y-bearing units and snug tighten them in the main direction of rotation.
  10. Tighten the locking collars to their final position, using a hook spanner with a stud engaging the hole in the circumference of the collar.
  11. Tighten the grub screw in the eccentric locking collar of both units to the tightening torque listed in the product table.
