AI Technical Summary
Under high load conditions, the deformation of the rubber-coated liner in existing rubber-coated bearings increases, resulting in uneven stress and large differences in rotational inertia, which easily leads to delamination.
An anti-slip mechanism is installed between the bearing body and the rubber liner, including spiral anti-slip grooves and anti-slip strips. The interlocking structure of the grooves and blocks increases the adhesion and friction to prevent slippage.
It improves the ease of use of rubber-coated bearings, prevents slippage, and enhances the firmness and adhesion between the rubber liner and the bearing body.
