Properties

The MR-1 trademark identifies a range of bearings composed of a metal grid housed CuSn6 within PTFE (polytetrafluoroethylene) loaded with solid lubricants (without lead, complying with the European Parliament’s “ELV"directive 2000/53/Ec).

The bronze grid gives the bearings the mechanical strength and the formability required to manufacture the finished parts; the loaded PTFE gives the MR-1 bearings a low friction factor and a high chemical resistance, entirely similar to those features by pure PTFE.

Thanks to their composite structure, the MR-1 bearings provide the best match of mechanical strength, thermal conductivity and low friction factor. The available products are cylindrical and flanged bearings, washers, belts and cast-to-size parts with thickness standard from 0,480 mm, 0,780 and 0,980 (0.019, 0.030 & 0 .039 inch).
