WF WB802 Self-Lubricating Bronze Bearing Bushing with Lubrication Holes FB092 Flange Bush - 120N/mm² Load Capacity, -100℃ to +200℃ Temperature Range
WF WB802 self-lubricating bronze bearing bushing with lubrication holes (FB092 flange bush) is manufactured from high-grade alloyed, hot-rolled phosphorous tin bronze. These sliding bronze bearings are engineered to withstand heavy loads and provide excellent shock resistance.
The entire bearing surface features punched-through holes that enhance lubricating properties, reduce maintenance requirements, and minimize friction during both startup and continuous operation.
Primary Material: CuSn8P0.3 (DIN ISO 4382-2:1991)
