The TE 57 Pressurized Lubricity Tester is a development based the standard TE 77 High Frequency Friction Machine. It incorporates a pressurized test enclosure with moving parts sealed by stainless steel bellows.

    Load is applied manually by means of a linkage mechanism acting through transverse bellows. The complete test assembly may be removed from the test machine for cleaning purposes. The unit incorporates a standard SUPERSLIM interface and COMPEND 2000 sequence programmable control and data acquisition software.
