A bearing assembly comprises a bearing wheel with a rotational axis, the bearing wheel including and extending radially between an inner surface and an outer surface, wherein the inner surface at least partially forms a bore, the bore extends axially through the bearing wheel along the rotational axis, and the bore has a cross-sectional geometry configured to receive a rotatable shaft with a complementary cross-sectional geometry, and wherein the outer surface extends circumferentially around the rotational axis, and the outer surface has a circular cross-sectional geometry. The bearing assembly also comprises a bearing collar comprising a collar base and a collar mount, wherein the collar base includes an inner surface configured to circumscribe and slidingly engage the outer surface of the bearing wheel, wherein the collar mount projects radially out from collar base to a distal mount end, and wherein a plurality of mounting apertures at the distal mount end extend axially through the collar mount, and the mounting apertures are configured to respectively receive fasteners for securing the collar mount to a stationary structural member.

An improved bushing assembly for a solar tracker is provided. The bushing assembly includes a bushing that is seated within a ring-shaped bracket. The bushing includes an annular ridge that is disposed within an annular channel in the bracket. Alternatively, the bracket includes an annular ridge that is disposed within an annular channel in the bushing. In each configuration, the bushing is retained in position during installation of the bracket. The bushing defines an internal passage for a solar tracker crossbar and provides complete rotational freedom for the crossbar about its lengthwise axis and limited rotational freedom for the crossbar about the remaining orthogonal axes. Additional features including side skirts for minimizing the entry of debris between the bushing and the bracket, a resilient latch for securing bracket sections together, and vertical openings in the bracket sections to allow debris to escape.

A lattice bearing support includes a circular inner structure having a center axis and an inner radial surface, an inner rim projecting axially inward from the circular inner structure toward the center axis, a circular outer structure located outward of the circular inner structure with respect to the center axis and having an outer radial surface, an outer radial flange on the circular outer structure that projects radially outward from the outer radial surface, and a number of struts extending radially between the circular inner structure and the circular outer structure.

A concentrated high-speed rigid hub allows for heavier planters, high-speed planting and seeding devices in multiple and multiple challenging applications such as no-till, high cation exchange capacity (CEC) soils, compact soils, moist soils, high concentrations of stubble and or Bacillus thuringiensis (Bt) crops, and cover or green crops with massive structured root systems. The hub is made of one of high strength forging steel and medium carbon cast steel, whereby the hub lessons hub flexing, hub bending, cracking and premature failure. The hub comprises rigid, heavy duty deep bosses or gussets which increase structural strength and maximize the strength of attachment points adapted for either bolts or rivets attachment to a blade or object.
