Without gear

Whatsapp:+8617702586093

How to use the limit curve
• Select for one bearing the associated load curve
• The solid line shows the utilization limit curve
for the raceways
• The stippled line shows the utilization limit curve
for the bolting

Product information valid for the
3 types of L’Shape slewing bearings
• L-shape bearings only to be used in compression.
For hanging conditions please contact WCB
• Range : from 500 mm to 1200mm external diameter
