Technopolymer bushing, Digidur Type J
Color code: yellow 
Description
Didgidur Type J is a selflubricating bushing with good stick/slip ability. Well suited for applications in low temperature, medium- to heavy- loads during slow speed or where there is a lot of regular or irregular tempo-changes and/or start/stop movements. Type J also performs very well during high speeds. It has low friction coefficient and hass good abrasion resistance. Low absorption. Good for radial, linear and oscillating movements.
