A roller bearing installation, in which one or more roller bearing assemblies (30A, 30B, 30C) are prepackaged in a housing (18) having corresponding recesses (28A, 28B, 28C) receiving each bearing assembly (30A, 30B, 30C). An angled gib plate (52A, 52B, 52C) is bedded in each recess, each gib plate

A roller bearing installation, in which one or more roller bearing assemblies (30A, 30B, 30C) are prepackaged in a housing (18) having corresponding recesses (28A, 28B, 28C) receiving each bearing assembly (30A, 30B, 30C). An angled gib plate (52A, 52B, 52C) is bedded in each recess, each gib plate (52) including an inclined section (54) mating with an inclined surface (58) on a bearing assembly cover (72) to allow a bearing depth adjustment by lengthwise adjustment of the bearing assembly (30) in its recess, enabling position adjustment of the supported structure (10) and bearing preload adjustment. Accurate alignment of the bearing assembly (30) is achieved by a ball plunger (100) urging the same against a guide surface (57) of the gib plate (52). A fixture (110) is used to precisely locate each gib plate (52A, 52B, 52C) in a recess (28) whjile a moldable bonding material (109) in which each gib plate (52) is bedded sets up. Electromagnetic coils (146, 148) are used to releasably hold each gib plate (52) on a respective locator arm (134, 136) during the process.

A method of installing a roller bearing assembly (30) of the type including a track member (66) defining a track surface (68) for recirculation of a series of roller elements, (70) with a bearing cover (72) enclosing said track member (66) to confine said roller elements (70), but with said roller elements (70) exposed on one side so as to be able to roll on a supporting surface (34), said bearing assembly (30) to be installed in a structure (18) supported on a linear surface (34) of a supporting structure (14) by said bearing assembly (28), comprising the steps of: fabricating a housing structure (18) with a recess (28) formed therein defined by a bottom and a plurality of sides to be able to receive said roller bearing assembly (30) so as to adjoin the bottom of said recess (28) and extending past the sides of said recess so that the rollers protrude out of said recess (28); fabricating an angled gib plate (52) comprised of an inclined section (54) and a straight guide section (56) extending alongside each other; forming an inclined surface (58) on the top of said bearing assembly (30) corresponding to said inclined gib plate section (54), and a guide surface (67) on the side of said bearing assembly parallel to said bearing axis; locating said gib plate (52) in a predetermined position in said recess with said inclined section extending along the bottom of said recess and said straight guide section extending along one side of said recess; fixing said gib plate (52) in said predetermined position in said recess; installing said roller bearing assembly (30) in said housing structure (18) with said inclined and guide surfaces (58, 67) against surfaces (55A) of said gib plate inclined and guide sections (54,56); mounting said housing structure (18) to said supporting structure (14) with said guide surfaces (57, 67) aligned with the direction of relative travel; and, adjusting the position of the roller bearing assembly (30) in said recess along the direction of said bearing axis to obtain proper bearing assembly depth by movement along and in engagement with said inclined section (54) and guide section (56) of said gib plate (52) and fixing the roller bearing assembly in said recess in said adjusted position by connecting (60,64) said roller bearing assembly to said housing structure to prevent relative movement therebetween in either direction along said bearing axis.
