With the increasing demand for maximum power density, such as transmitting greater forces and torques in compact structures, engineers across various industries face significant challenges. JiaoKai provides solutions that increase friction to withstand higher shear forces at connection points or transmit greater torque at bolt connections. JiaoKai friction shims offer a simple and cost-effective method to increase the transmitted torque or force by 3 to 5 times compared to traditional systems, without the need to modify the joint design.
Jiao Kai friction shims are made from a nickel-coated steel base, partially embedded with diamonds, which create a micro interlock with the mating surface as they shrink. These shims are easy to assemble and can be reused after disassembly. They are sufficiently thin to achieve a perfect fit with tolerances. The lightweight, compact design increases the maximum load and peak torque of bolt connections.
Jiao Kai friction shims have proven to be reliable and effective across various industries, including automotive, general mechanical engineering, machine tools, marine engineering, wind and hydropower generation, and aerospace. Our technical experts possess years of application experience and internal testing methods.
Significantly improves the static friction coefficient.
Unaffected by oil film.
Easy to retrofit and upgrade.
Prevents micro-vibration wear.
