Product Description
Metal-Polymer Anti-Friction Plain Bearings
Good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
Very good performance in lubricated applications particularly in marginally lubricated applications
Suitable for linear, oscillating and rotating movements
Lead-free material match RoHS specifications.
Bearing forms made to order: standard forms in special dimensions, half-bearings, special shapes obtained by stamping or deep drawing, bearings with locating notches, lubricant holes and machined/stamped grooves, customized bearing designs
