FB090

Structure

Features and Application

    Thin-wall bronze(CuSn8P) bearing material for lubricated applications.
    Bearing surface is indented with diamond shaped pockets for grease lubrication.

    Thin wall wrapped bronze(CuSn8P) bushing.
    Low maintenance.
    Diamond shaped pockets indented on the bearing surface for grease lubrication.
    Optimum performance under relatively high loads and low speeds.
    Initial pre-lubrication at assembly required.
    Widely used in hoisting machines and other construction machines,automobiles,tractors,trucks,machine tools and some mineral engineering.

Availability:
    Cylindrical bushes, flange bushes, thrust washers and strips.
    Non-standard parts.
