K68 is a guide ring designed to be used for rod applications.

PRODUCT ADVANTAGES
• Easy , snap-in fitting
• Medium load-bearing capacity
• Prevents hydrodynamic pressure due to the K interval
• Very good dimension stability during operation temperatures
• Chamfered edges prevent pressing into the corner radiiof the groove
• Wide range of dimensions
• Economical guiding solution

APPLICATION
Construction machinery , cranes , injection moulding machines , agricultural machinery , light to medium duty cylinders.

INSTALLATION
Easily assembled into the housing by hand. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.

NOTES
When designing the cylinder K68 guide ring should be placed where it has direct contact with the media. K68 is not suitable for dry working conditions. Surface contact pressure value might drop due to the temperature increase.
