BS STANDS

The Stands patented by PERT Long Product Division are “BS-BiSupport” type. This is a technologically advanced solution which grants to the train the particular characteristics of flexibility and sturdiness.

These stands preserve the advantages of compactness and rapidity of ring change which are typical of the cantilever stands. In the same way they maintain and increase the advantages of the housingless stands, thanks to the adoption of a double support on the ring shaft . In this way there will be an important reduction of settlings practically a complete elimination of the flexotorsional problems.

The compact dimensions and the other characteristics of this type of stand permits to obtain:

• Absence of chocks
• Absence of spindles
• - 85% spare parts
• Patented rings shaft made in alloy steel assure high bearable loads (cold billet) compared to the cast iron rolls weak resistance.
• Eccentric regulation (one complete turn represents 5 micron of gap)
• Short production changing time
• Highly reduced maintenance time and cost
• Reduced cost in foundations
• Thanks to the compact design of BS stands the buildings dimension are reduced
• No piping on board
• Reduction of erection times
• Long bearings life
• Lower cranes load capacity
