RCSM rubber covered, cylindrical O.D. insert bearings are designed for domestic heating, air conditioning, ventilating equipment, and many other applications where low cost, light duty, and noiseless operation are essential.
Please be aware that there is also a lighter 1" HVAC insert bearing with part number RU1121-16 which is similar in appearance to the RCSM-1 but comes with a smaller 2.24" outer diameter on the rubber sleeve.
