Assembly features: 

assembly features of laminar ring
We support all above assembly features for your convenience.

FK3:

All FK3 series is single wound Laminar Rings used for bearings. Its protective ability is less than FK6 series, but still get the job done. FK3 prevents ingress of dust and environmental moisture. The 5 ring types ASK or ISK ring sets have increased labyrinth effect. simply because these 2 types have more rings per set. Within 3 ring set config, IS laminar ring is easier to fit in the grooves. For 5 ring set config, The ISK is easier to fit in. generally speaking laminar rings for shaft is easier to install.

FK6:

All FK 6 series Laminar Rings are double wound laminar rings for bearings and the front of radial lip seals. Higher sealing performance is achieved by the FK 6 Laminar Rings when exuding grease. They also perform better, compared to FK3 series, in protection against dust, dirt and splash water.
FK 6 Laminar Rings benefited from the double wound nature, First, It has no gap, second, the double wound enable higher retention force. AS the FK3 series, ASKD or ISKD Perform better because they are 3 rings per set(the other types ISD and ASD is 2 ring per set). After your decided to choose 2 ring config or 3 ring config, then remember that ISD is easier to fit in than ASD for 2 ring config. For 3 ring config, The ISKD is easier to fit in.

Notes :

FK6:

         lSD,  1 set = 2 rings ( for shaft ).
        lSKD, 1 set = 3 rings(2 for shaft, 1 for bore) .
        ASD, 1 set = 2 rings( for bore).
        ASKD,  1 set = 3 rings(1 for shaft, 2 for bore) .

FK3:

         lS,  1 set = 3 rings(for shaft).
        AS,  1 set = 3 rings(for bore).
        lSK,  1 set = 5 rings(3 for shaft, 2 for bore) .
        ASK,  1 set = 5 rings(2 for shaft, 3 for bore).

We also produce US versions like VH & VS, WH & WS, EH & ES, WHT & WST, WHM & WSM, DNH & DNS series.
