Brake Line Roller Straightener Block
A five-roller straightening block for 3/16 in (4.76 mm) brake, fuel and copper-nickel line: three 624 bearings on the lower row and two offset above squeeze the tube to a 4.2 mm nip (0.56 mm set) so coiled line pulls through dead straight. 110 x 44 x 18 mm body with V-groove entry and exit guides, 3.4 mm self-tapping holes for M4x16 socket-head screws (the 7 mm head clamps only the bearing's inner race), and four 5.5 mm M5 holes to bolt it to the bench — or grip the 9 mm plate edges in a vise.
Flagged: hydraulic brake system. Not for safety-critical use without independent engineering review.
624 Bearing Appliance Slider Rail
A 150 x 30 x 18.5 mm roller rail that lets a heavy stand mixer, espresso machine or air fryer be pulled out from under the upper cabinets with one hand instead of being dragged across the counter. Each rail carries two 624 bearings (4 x 13 x 5 mm) on M4 x 25 screws — 4.5 mm clearance hole with a recessed head on one side, 3.4 mm self-tapping thread on the other — so the outer races sit 1.5 mm proud of the rail and roll; the 22 mm wide top tray with a 2.5 mm rim keeps the appliance foot from walking off. Print two rails per appliance.
Shower Door Top Roller Hanger
Replacement top hanger for framed sliding shower doors whose original roller cracked and whose OEM part is long discontinued — a 624 bearing (4 x 13 x 5 mm) becomes the wheel, clamped on an M4 x 20 screw through the 4.5 mm axle bore, so the outer race rolls on the existing track. The 64 x 24 x 5 mm plate carries two 4.6 x 11 mm slots giving 10 mm of height adjustment to re-square a dragging door, and the M4 screw head recesses 3 mm into the back so the plate sits flat against the door stile.
624 Bearing Servo Saver Bellcrank
A compliant steering bellcrank for RC trucks and robot linkages: the hub presses onto a 624 bearing (4 x 13 x 5 mm) and drives two 36 mm output arms through a pair of spiral leaf flexures, so curb strikes deflect the arms ~10° and spring back instead of stripping the servo. 83 x 83 x 7.5 mm, M3 clearance holes at both tie-rod arms and two link positions on the input arm, with the arm sides hitting the ring ends as built-in over-travel stops.
608 625 624 Bearing Sort Rack
A bench rack that stops 608, 625 and 624 bearings rolling around in a drawer: four vertical chutes with 22.2 mm, 16.2 mm and 13.2 mm bores take bearings in from the top and hold 6-8 of each size, tubes stepping down by size so the big skate bearings and the small 624s are never mixed up. The 124 x 30 x 4 mm plate carries two 4.5 mm holes for M4 screws to a bench, wall or pegboard.
