Welded Hardened Steel Bushings
Frebecker offer several patented bushing designs, in a broad range of sizes, as well as carburized and ground sleeve bearings. To determine the best design for a particular application, designers should first consider the constraints of the work environment, including abrasion, loading, corrosion and maintenance requirements.
When selecting the appropriate bushing for each application, the pressure-velocity (PV) factor is particularly important. For joints operating under dry or greased conditions, the thermal energy generated by friction is proportional to the pressure (P), the sliding velocity (V) and the friction coefficient (F) between the sliding surfaces. Given a pair of materials, there is a maximum PV beyond which surfaces can no longer absorb the generated friction, leading to seizure or melting of the surfaces. Each of the HEF bushing designs has its own PV curves, which are indispensable for determining the appropriate bushing for particular applications and operating conditions.
In addition to bushings and bearings, We supply a broad range of other friction components, including pins, shafts and sleeves; slides and pads, washers, rollers, screws and nuts.
