K33 ROD SEAL 105X115X11.5 PU

K33 is a single acting rod seal designed to have inner lip shorter than the outer lip and additional sealing lip which improves the leakage behavior and , at the same time , prevents the entry of contaminations from the wiper side.

PRODUCT ADVANTAGES
• High wear resistance
• Superior sealing effect with the secondary lip
• Secondary sealing lip provides extra protection against the ingress of dirt particles
• Wide range of dimensions
• Simple groove design
• Easy assembly into closed grooves

APPLICATION
Construction machinery , fork-lift trucks , injection moulding machines , agricultural machinery , loading platforms and standard cylinders.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.

INSTALLATION
Easily assembled into closed grooves according to the minimum diameter values that are given in the below table. Open grooves or special assembly tools should be used for the values that are outside this table. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

MINUMUM DIAMETER VALUES FOR CLOSED TYPE OF GROOVES
(D-d)/2 (mm)	4	5	6	7.7	10	12.5	15
dmin (mm)	25	30	40	50	80	100	105

NOTESThe permissible sealing gap values of K33 rod seal is givenin the below table.

PERMISSIBLE SEALING GAP
	Smax (mm)
t=(D-d)/2(mm)	150 Bar	250 Bar	400 Bar
t≤5	0.30	0.20	0.15
t>5	0.35	0.25	0.20

Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
