Y-bearing plummer block units with a pressed steel housing
Y-bearings with grub screws
- Remove any burrs on the shaft with emery cloth or a fine file, wipe clean with a cloth.
- Mount any components that are on the shaft between the two Y-bearing units.
- 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).
- Make sure the housing base and mating surfaces are clean and free of any debris or burrs.
- Position the base of each housing on its support surface.
- 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.
- Carefully align both Y-bearing units, using the shaft. Fully tighten the attachment bolts or nuts.
- Align the shaft in the bearing arrangement axially and, if possible, turn it a few times.
- 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
- Remove any burrs on the shaft with emery cloth or a fine file, wipe clean with a cloth.
- Mount any components that are on the shaft between the two Y-bearing units.
- 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).
- Make sure the housing base and mating surfaces are clean and free of any debris or burrs.
- Position the base of each housing on its support surface.
- 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.
- Carefully align both Y-bearing units, using the shaft. Fully tighten the attachment bolts or nuts.
- Align the shaft in the bearing arrangement axially and, if possible, turn it a few times.
- 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.
- Tighten the locking collars to their final position, using a hook spanner with a stud engaging the hole in the circumference of the collar.
- Tighten the grub screw in the eccentric locking collar of both units to the tightening torque listed in the product table.
