Rubber Bumpers
Rubber bumpers are threaded components surrounded by a rubber jacket that are used to absorb the vibration given off by motors or other moving elements preventing damage to components in robotic applications. They help reduce maintenance, wear, noise, and repair costs when installed in robots.
The threaded stud or tapped hole on one end of rubber bumpers allows them to be directly connected to motors, mounting frames, machine guard doors, and many other components you would find in a robotic application. The rubber jacket over the other end allows rubber bumpers to act as end stops, mounting feet, or buffers on machine guard doors. Rubber bumpers can be installed onto motors that operate at high speeds to absorb vibration and prevent damage to the motor or other components of the robot. For example, many robots move along uneven factory floors. Having a rubber bumper installed ensures the motor will be isolated from the vibration as the robot moves around the factory, allowing it to run smoothly and efficiently. They are also used as end stops to prevent the robot from moving too far in one direction, as mounting feet at the base of larger robots to prevent shock to floors, and as buffers on machine guard doors to protect the frame of the door.
Ruland rubber bumpers have jackets with 55 shore A hardness for a balance of shock absorption and rigidity. The metallic cores are made from 304 stainless steel for high corrosion resistance or zinc-plated steel for higher strength and general-purpose use. Tapped holes and studs have inch threads ranging from 1/4”-20 TPI to 3/8”-16 TPI and metric threads from M3 to M16 available on our site. All rubber bumpers are sourced from JW Winco and stocked in our Marlborough, Massachusetts location.
