5 / Bushings composite POM - bearings for heavy loads
PERFECT COMBINATION LOW MAINTENANCE AND TOUGH OPERATING CONDITIONS
Slide SKF POM composites are commonly referred to as předmazaná, because even a slight trace of lubricant ensures
that the bearing will be a long time to submit a satisfactory performance. A special sliding material requires lubrication
only very rarely. Slide SKF POM Composite therefore fill the space between the bearings, which require regular maintenance,
and maintenance-free bearings. They are made in all sizes according to ISO 3547
and DIN 1494th SKF also offers a sliding axial sliding rings and belts.
