High Load FB090 Bronze Thrust Washer CuSn8 Tin Bronze Thrust Washer Diamond Lubrication Pocket For Excavator Boom Hinge
[Heading 1] FB090 Phosphor Bronze Thrust Washer with Diamond Oil Pockets
Wrapped tin bronze flat thrust bearing washer for heavy-duty low-speed applications
[Heading 2] Product Overview
Our FB090 bronze thrust washer is manufactured from high-quality CuSn8 phosphor bronze, featuring precision diamond-shaped lubrication pockets on the sliding surface. These oil pockets retain grease or oil to form a continuous lubricating film during operation, effectively lowering friction coefficient and reducing wear.
This flat thrust washer is designed to withstand axial loads for oscillating and slow rotating movements. Widely adopted in hydraulic cylinders, construction machinery, automation equipment, agricultural machines and mining machinery. Custom inner diameter, outer diameter and thickness are available to match your drawing requirements.
