ABSTRACT:
An improvement in a bearing retainer construction for use with a bearing apparatus having a king pin for use with a swivel caster. The swivel caster has a swivel plate with a central opening therethrough. A pair of annular bearing ball retainers are disposed upon opposite sides of and spaced from the swivel plate. A plurality of bearing balls are disposed between the retainers on opposite sides of the swivel plate for snug rolling engagement with the retainers and with the swivel plate. The king pin is received in openings through the annular bearing ball retainers and has retaining structure thereon to prevent relative axial movement between the retainers and the king pin. A positive mechanical securement is provided between the pair of bearing ball retainers and the king pin to prevent a relative rotation between the bearing ball retainers and the king pin.
