Abstract
Abstract A bearing pack and mounting therefor which minimizes side forces, with the pack having a body member of a cross shape with a central section defining upper and lower lateral guide surfaces for at least two laterally spaced circuits of rolling bearings and with a lateral section extending beyond both sides of the central section intermediate the height thereof to have the lower surfaces define load bearing surfaces, additional members are associated with the body member for retaining the rolling bearings in their travelling circuits and the mounting includes a frame element with a recess for receiving the pack with a backup member aligned with said central section to permit movement of the pack relative to said backup member about plural axes to assist in obtaining uniform loading of the rolling bearings.

Dependent Claim
68 words
In a structure as defined in claim 1, said central section extending between said rolling bearings and outwardly beyond the axis of rotation thereof and of a width to provide substantial separation of said two circuits to define a wide tread width for the pack and resultant effective force under load to rotate said pack about said axes as required to achieve uniform loading on said rolling bearings.
Claim 4
Dependent Claim
156 words

Claim 5
Dependent Claim
156 words
A roller bearing pack assembly including a paCk body and a self-aligning mounting therefor, said pack body having a cross-shaped member with a central section defining upper and lower lateral guide surfaces for two laterally spaced circuits of roller bearings and with a lateral section extending beyond both sides of said central section intermediate the height thereof to have the lower surfaces thereof define load bearing surfaces, a series of roller bearings in each of said circuits for rolling successively along said load bearing surfaces in a load zone, means associated with said member for retaining the roller bearings in said pack, and said mounting including a frame with a recess for receiving the pack with a backup member aligned with said central section, and means mounting said pack in said recess to permit movement of said pack relative to said backup member about a plurality of axes to achieve uniform loading on said roller bearings.
Claim 6
Dependent Claim
56 words
A structure as defined in claim 3 wherein said backup member has a width substantially the same as said central section, locating means on a side of the pack for engaging a wall of the recess and a spring on the opposite side of the pack yieldable to permit movement of said pack about said axes.
Claim 7
Dependent Claim
41 words
A structure as defined in claim 4 wherein a pair of springs on said pack extend outwardly therefrom to engage the bottom of said recess and generally align the pack in said recess during assembly and final loading of the pack.
Claim 8
Dependent Claim
84 words
A structure as defined in claim 3 wherein the part of said central section defining the lower lateral guide surfaces extends between said roller bearings outwardly beyond the central axis thereof to provide a major area of contact between the ends of roller bearings and said guide surfaces as the roller bearings enter said load zone to square up the roller bearings and cause the axis of rotation of each roller bearing to be perpendicular to the path of travel of the roller bearing.
Claim 9
Dependent Claim
60 words
