Bearings are indispensable components in many mechanical devices, playing a vital role in reducing friction between moving parts. Two common bearing arrangements are Between Bearings (BB, double-supported) and Overhung (OH, cantilevered). These configurations each have distinct characteristics and suit different working conditions.
"Between Bearings" means the shaft is supported at both ends, typically by a pair of bearings. This design effectively distributes radial loads and controls shaft deflection due to dual supports, ensuring stable and smooth rotation.
"Overhung" (cantilevered) refers to the shaft supported at only one end, with the other end extending as a cantilever. This simpler design is prone to vibration from unbalanced forces, especially under high loads or speeds. To mitigate this, dynamic balancing and suitable bearing selection for extra radial loads are critical.
When dealing with high-speed rotating equipment, precision machinery requiring strict control of axial and radial runout, or scenarios subject to large radial loads, the BB series should be considered; the OH series, on the other hand, is more suitable for cost-sensitive small equipment, applications with limited installation space, or working environments where a certain degree of vibration is acceptable under light loads.
