Maintenance Free Bearings




Application:
On this large floating shearleg the customer changed to direct load measurement by
means of load cells in the pins of the main blocks. This is difficult to combine with
lubrication therefore DRIE-D was invited to supply maintenance free D-Glide bearings
for this high load (average bearing pressures over 120 MPA) application. After removal
of the support brackets it was found that the bronze layer in there had also worn out.
In less than a week DRIE-D made bearing segments with exactly the correct thickness
and glued them in brackets, now the brackets also no longer require lubrication. Any
other solution would have taken far more time and would have been far more expensive.



Advantages of the D-Glide solution
- Maintenance free
- Modest demands on the shaft materials
- Short delivery time
- Low costs
