In workshops and on production lines, small vibrations and sliding parts can cause noise, scratches, and misalignment. The 3M Bumpon SJ5300 BL set provides a practical solution: a transparent, self-adhesive polyurethane bumper assortment that absorbs shock, prevents slipping, and protects surfaces. The set includes 100 hemispherical bumpers in three sizes—50 pieces of SJ5302 (7.9 mm diameter, 2.2 mm height), 30 pieces of SJ5312 (12.7 mm diameter, 3.6 mm height), and 20 pieces of SJ5344 (19.1 mm diameter, 7.6 mm height). Each bumper features an acrylic adhesive backing for secure attachment to clean, dry surfaces.
