Friction free roller spring perch

A method for creating a roller spring perch, comprising:

• manufacturing a steel bracket having a bed with two shaped regions formed to accommodate mounting to a suspension spring, holes for mounting to shock absorbers, and two sidewalls each having a hole of a first diameter, the holes aligned on an axis orthogonal to the sidewalls;
• procuring two snap rings;
• procuring four bearings, each bearing having a second outer diameter, a third inner diameter, and a first width;
• machining a steel cylindrical bearing housing of a fourth diameter with a first length, a central bore of a fifth diameter, and counterbores of a sixth diameter on each end to a second length from each end;
• machining a bearing shaft with a central axis, the bearing shaft of a third length greater than the first length, the bearing shaft having central region of a seventh diameter less than the fifth diameter, bearing lands to each side of the central region, the bearing lands having each an eighth diameter as a press fit to the third inner diameter of the bearings, a fourth length twice the first width of the bearings, and a snap ring grooves at an end of each bearing land away from central region, the bearing shaft further having a flattened region on each end with a through hole at a right angle to the central axis of the bearing shaft;
• assembling the bearing shaft to the bearing housing with two of the four bearings pressed onto each of the two bearing lands and the bearings fit into the counterbores of the bearing housing;
• assembling the snap rings in the snap ring grooves of the bearing shaft, completing an assembly of the bearing housing, the bearing shaft and the bearings;
• placing the bearing housing with the bearing shaft and bearings centered through the holes in the sidewalls of the steel bracket;
• and
• spot welding the bearing housing to the sidewalls of the steel bracket.
