Repairing or fixing bar stool swivels having a broken plastic race, or a swivel in which the bearings are falling out, or loose and wobbly cannot be repaired. It must be replaced.
Other reasons for replacement
• powdery and sometimes greasy floor residue
• rough or grinding noise
• ball bearing(s) on the floor
• bouncing side to side when leaning
• broken memory return spring
Removal is not difficult. It is only to remove the screws or bolts from the swivel plates. Some swivel chairs or stools have an round access hole in which to insert a screwdriver to remove the fastener. Others will require that the swivel is 1/4 turned so that the fastener can be accessed.

The most difficult part is determining whether it is Flat or Tilted.
How do you know whether your bar stool seat swivel is flat or tilted? Choose either method.

Bar stools like this only use a Flat Bar Stool Swivel. 
 With the seat or swivel removed, observe if both steel plate edges (on all four sides) are parallel to each other. If they are the same distance apart you need a Flat Bar Stool Swivel.

 Bar stools with a back may have either Flat or Tilted Bar Stool Swivel
 If stool is not disassembled, measure from under the seat to the floor at both front and rear. If seat front is higher, it is a Tilted Bar Stool Swivel

The plate size is not too important, but the mounting screw hole pattern (measured from one screw to the next screw) being the same, can make installation easier.
Example:
A swivel plate measuring 6 1/4" commonly has a mounting screw pattern of 5 1/4".
Many of our swivel plates measure 6 3/4" (frequently called 7"), but yet the mounting pattern is still 5 1/4" and will replace the smaller plates perfectly. Your 6 1/4" plate is a lighter gauge steel and may have fewer ball bearings as well.
