Rubber bumper feet with washer inside are intended to combine a flexible contact body with an internal hardware feature. The washer's position within the part is significant because it affects how the fastening interface relates to the surrounding rubber. The external shape alone cannot show whether the washer seat and molded section suit the intended mounting and handling forces.
Provide an internal section that identifies the washer dimensions, location and method of retention. Confirm whether the washer is molded in place or incorporated through another specified construction. Show the mating fastener and the direction of force at the foot, including sideways movement that may occur when the supported item is repositioned. The rubber section around the hardware must be evaluated in that complete arrangement.
ETOL offers custom dimensions, material, hardness and color for bumper components. Include the washer specification as a controlled part of the inquiry, rather than leaving it defined only by a product photograph. Sample inspection can then address the visible rubber profile and the location of the internal feature. Any required checks of the washer-to-rubber relationship should be agreed for the selected construction.
After mounting rubber bumper feet with washer inside, examine the area around the fastening point for distortion and confirm that the contact face remains properly oriented. During representative handling, look for movement between the rubber body and hardware or local damage around the internal seat. Do not attempt to correct such movement merely by increasing fastener tightness without reviewing the assembly. Keep debris away from the contact base and inspect the part when the equipment is serviced. For repeat orders, retain the internal section and washer details with the approved sample so an unseen change is not accepted simply because the outside of the foot looks unchanged.
Photos illustrate structure or material only. The external shape alone cannot show whether the washer seat and molded section suit the intended mounting and handling forces. 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.
