Rubber feet with iron washer reinforcement include a metal element within the fixing area. That element can distribute fastening pressure locally, but the complete support still depends on the rubber geometry, receiving component, fastener, and applied load. The washer does not establish a load rating by itself.
Check how the selected fixing seats against the reinforced area and how much engagement is available in the base. A screw that bottoms out early may appear tight without securing the foot as intended. Excessive tightening can also distort the surrounding rubber and change its resting contact.
Evaluate the fitted feet as a set under the complete product's weight. Look for rocking, uneven compression, and any hard hardware approaching the supporting surface. During service, inspect attachment security and wear beneath the rubber. If the foot begins to rotate or deform differently, investigate the fixing and support geometry together rather than tightening until the flexible body is visibly squeezed out of its intended shape.
Photos illustrate structure or material only. Excessive tightening can also distort the surrounding rubber and change its resting contact. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.
FIND THE RIGHT FIT
Choose hemispherical, tapered or recessed rubber feet and compare the mounting dimensions. All values are in millimeters. Use the drawing labels for each product; a dash marks a dimension not supplied in the source.
12 sizes for recessed rubber feet, including flat and rounded bases. The Base column identifies the lower-edge style. C is recess depth; the appearance rendering shows a rounded-base example.
