ABSTRACT:
A sleeve bearing (20) having an outer cylindrical surface concentric to a center (24) and an inner bearing surface for surrounding a cylindrical journaled member (26) in closed spaced relationship. The inner bearing surface has oppositely disposed first (28) and second (30) crown surfaces which are divided by a dividing diameter (A) and first clearance surfaces (32) extending circumferentially from opposite extremities of the first crown surface (28) and second clearance surfaces (34) extending circumferentially from opposite extremities of the second crown surface (30) and intersecting the first clearance surfaces (32). The crown surfaces (28, 30) extend circumferentially on a first radius (r) which closely approximates the radius of the journaled member (26). The clearance surfaces (32, 34) extend circumferentially on a second radius (r') which is greater than the first radius (r). The first and second radii (r, r') intersect at the junctures (38) between the crown surfaces (28, 30) and the clearance surfaces (32, 34). The first radius (r) for the first crown surface (28) has a first axis (40) on the dividing diameter (A) and spaced from the center (24) on one side thereof and the first radius (r) for the second crown surface (30) has a second axis (42) on the dividing diameter (A) and spaced from the center (24) on the opposite side thereof from the first axis (40). The second radius (r') for the first clearance surfaces (32) has a center (44) spaced radially outwardly of said second axis (42) whereas the second radius (r') for the second clearance surfaces (34) has a center (46) spaced radially outwardly from the first axis (40).
