The prompt
A mechanical garage door roller assembly designed with precise engineering dimensions, consisting of the following parts: 1) A rectangular mounting bracket with screw holes for mounting to the bottom of a garage door. 2) A cylindrical housing containing a compression spring and an internal piston stop. 3) A swivel joint connected to a wheel carrier, allowing an approximate 15-degree side-to-side swivel range. 4) A V-groove wheel with an overall diameter of 70 mm and an overall width of 35 mm, featuring a central groove width of 7.2 mm, a groove width of 7.0 mm at the base, and an approximate groove depth of 5 mm. 5) Clearance specifications requiring a total approximate height of 140 mm, a distance of 26 mm from the bottom of the door to the top of the guide bar, and an 8 mm clearance from the bar to the concrete floor. The V-groove wheel is engineered to run smoothly on a 5.5 mm steel bar guid
