GLYCODUR® A / GLYCO® 94
Key Features
- Low maintenance operation with initial lubrication
- High pv-value
- Low wear
- Low seizure
- Rotating, oscillating and axial motion possible
- Available in a wide range of standard dimensions in accordance to ISO 3547
For many high loaded applications maintenance free bearings do not achieve the needed service life within an acceptable period. Reasons could be:
- Long-term stress
- High edge load
- Operation in rough environment
GLYCODUR® A dry sliding bearings have a steel base and a 0.2 to 0.4 mm sintered tin bronze layer. The principal characteristic of these bearings is the polyoxymethylene (POM) top layer, which is solidly joined to the sintered bronze. The surface layer, which is 0.3 mm thick features pockets for lubrication grease. GLYCODUR® A sliding bearings are therefore to some extent unaffected by misalignments including related edge loads.
