These suspension bearing installation pilots are bearing specific. In order to install a new bearing without damage, the bearing must be properly centered according to Inside Diameter. In addition, the pressure applied by the pressing operation must be applied to the outer race of the bearing--requiring the OD of the bearing to be matched as well. Please see the application chart in the accompanying pictures. These installation guides guides have a shortened pilot allowing for the increasingly tight spaces insided of suspension bearing linkage assemblies. Manufactured in the USA. These guides are part of the "Modular Series" of suspension bearing tools by Real World Cycling.
