Bearing selection for low-speed appliions | Kaydon

Resistance to vibration and shock affects long bearing life at low speeds, even though such loading is more often the result of external forces than the ialance of rotating masses or non-precision components. (The slewing ring bearings that rotate tank turrets for example, must be designed to withstand the shock of the cannon firing.)

- The Latest in Slewing Ring Bearing Technology

Sliding slewing ring bearings have excellent vibration-dampening ability. When tested, our PRT slewing ring bearings outperformed roller bearings in atmospheric conditions at 5G’s. The vibration caused the balls in the roller bearing to fly out, while the sliding slewing bearing absorbed the vibration and remained completely intact. Temperature.
