DZE bearing design and production range
We offer a recommended range of 42 items balls and crossed rollers designs in
size range from 400 mm to 1900 mm
• Easy to select
• From stock
• Interchangeable
• Cost effective solution
• Compete with market leaders
• Reference range for new products
Ball design -is a simple design for low demanding applications and allows
• A better static capacity for oscillating movements
• A better resistance to structure deformations (clearance)
• A lower friction rate
Crossed roller design -is intended for the most demanding applications and
allows
• A better dynamic capacity and a long service life
• A better stiffness due to the preload
• A better resistance to false brinelling and vibrations
How to use the static limit curve
• Select for one bearing the associated load curve
• The solid line shows the utilization limit curve for the raceways
• The dotted line shows the utilization limit curve for the bolting
