PVB033 bimetal bearing is a kind of bimetal bush. This type self-lubricating bearing has common structure with other bimetal bearings.
Low carbon steel + bronze alloy (CuPb24Sn4)
Good anti-fatigue strength and carrying capacity
Suitable for middle speed and middle loading, oil lubrication situation
When soft alloy is plated on the bushing surface and with oil lubrication, PVB033 bimetal bushing can be applied in high speed internal-combustion engine and connect-rod.
