Precision fitting formaximum performance<\/h2>\n\t\t\t\t\t

The correct installation of laminar rings is crucial for the sealing effect, function and service life of the entire system. Even the smallest deviations in fit, preload or installation space can affect performance \u2013 especially at high speeds, temperature fluctuations or tight tolerances. <\/p>\n\t\t\t\t\t

Fey laminar rings are designed to be installed securely and to assume a defined, stable position after fitting. This page provides clear, practical instructions to help development engineers, fitters and maintenance technicians ensure optimum function. <\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/div>\n

The circumferential gap dimension (A) should be kept as small as possible in the design. The smaller the gap, the greater the labyrinth or sealing effect. <\/p>\n\t\t\t\t\t

If radial play and\/or tilting movements occur, please observe the information on the respective data sheets for the various ring arrangements under \u201cAxial and\/or radial play\u201d!<\/p>\n\t\t\n<\/div>\n

If prescribed fitting chamfers on the housing or shaft are not possible due to limited space, attachable tapered fitting sleeves or fitting strips should be used for housings and removable fitting cones should be used for shafts.<\/p>\n\t\t\t\t\t

When assembling the parts fitted with rings, do not simply press them on, but also move them radially and tap them axially to overcome the slip resistance.<\/p>\n\t\t\n<\/div>\n

1) Single and double wound laminar rings are spiralled into the grooves by axial expansion of the rings.<\/p>\n\t\t\t\t\t

2) If rings have to be fitted over a shaft into a groove, do not overstretch the rings radially as they will be permanently deformed!<\/p>\n\t\t\n<\/div>\n

1) Insert one ring end into the groove.<\/p>\n\t\t\t\t\t

2) Twist the rest of the ring in.<\/p>\n\t\t\t\t\t

Remove the retaining rings using a slotted screwdriver. To do this, insert the screwdriver into the disassembly recess and lever one end of the retaining ring out of the groove with a slight twisting motion. <\/p>\n\t\t\t\t\t
