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, 52C, 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) while 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.

Integrally adjustable way bearings

The present invention is an improved linear recirculating bearing assembly and method of making it. More particularly, the present invention is a linear roller bearing assembly in which the housing is manufactured of three primary parts, an upper bearing half, a race member and a lower bearing half. The race member includes one or more mounting pedestals having an upper surface finished to a high degree of flatness and parallelism with the lower surface of the race member. The upper bearing half and the lower bearing half include portions to define two recirculating bearing paths for recirculating bearing elements or rollers to recirculate about paths around the race member, with the upper and lower bearing halves being generally non-load bearings, so that they may be manufactured from low cost, low strength materials.

Recirculating bearing assembly and method of making

A recirculating bearing assembly and method of making it in which the bearing assembly includes a bearing path-defining structure having two primary pieces, the first being an elongated 'I' shaped member having an internal aperture extending through the elongated length and having integral end bearing returns formed as concave, inwardly facing rounded portions in each of the cross pieces terminating the elongated length and the second piece including flat upper and lower surfaces and fit within the aperture and having generally parallel upper and lower surfaces connected by rounded end portions. The second member defines the internal surface of each of two races for roller bearing elements.
