Engineering Plastic Flanged Bushing GFM Self-lubricating Sleeve Bearing 3-100mm

About this Product

These premium flanged maintenance-free engineering plastic bushings are high-performance polymer bearings designed for demanding industrial applications. Featuring an integrated flange for easy alignment and mounting, they offer exceptional mechanical strength, low friction and self-lubricating properties, making them ideal for high-load, low-speed rotating, sliding and oscillating movements.

Key Features

  • Flange Design: Built-in flange ensures proper alignment, prevents axial movement, and simplifies installation.
  • Wide Temperature Range: Continuous operation up to +130°C, short-term up to +220°C, minimum operating temperature down to -40°C.
  • High PV Value (Dry Running): Up to 0.42 MPa·m/s, suitable for high-load applications.
  • Resistant to UV radiation and radiation (up to 3·10² Gy), good resistance to alcohols, hydrocarbons, oils, fuels, and diluted bases
  • Installation Notes：
    These are press-fit bearings, requiring H7 tolerance housing holes and h9 tolerance shafts for proper installation.
    Recommended shaft surface roughness: Ra 0.8 μm to minimize friction and wear.
    Chamfer shaft ends at 20-30° for smooth installation.
    Do not use locating pins during installation, as they may damage the bearing or distort the inner diameter.
