PIVOT BEARING MAINTENANCE

One of the most important areas on the GSX style pinsetter for routine maintenance is the Pivot Bearing. This part is responsible for the raising and lowering of the sweep and the table.

A catastrophic failure of the Pivot Bearing that is responsible for the table, can lead to a major breakdown and the possibility of several parts failing. This Pivot Bearing carries the weight of the entire table and skipping the maintenance will cause it to fail.

The Pivot Bearing that lifts and lowers the sweep doesn’t carry as much weight but still needs to be maintained.

The Pivot Bearing and the attached chains will have tension on them from the weight of the sweep or table. Before starting any work on the pinsetter, follow the manufacturer’s safety procedures.

Both Pivot Bearings should have 1 drop of oil placed on the center bushing once per month. This is a great time to also inspect the condition of the chains. Chains should be wiped off with a dry rag and a light coating of Moly chain lube applied once per month.

The likelihood of the sweep Pivot Bearing failing is rare. The table Pivot Bearing can fail and below is a procedure for replacing it.

There are 2 options for replacing a pivot bearing shown below.
