540268A Bore 70 Mm, Support Rollers For Multi-roll Cold Rolling Mills, No Cage
The 540268A Backed bearings are suitable for heavy-duty rolling equipment such as multi-roll cold rolling mills. Classic applications include backing rolls in multi-roll mills, straighteners, bending machines, support rolls in Sendzimir mills, and work roll support systems in strip mills.
The 540268A bearing is a Support Rollers for multi-roll cold rolling mills with an inner diameter of 70 mm , an outer diameter of 160.02 mm, a width of 90 mm. case hardening steel rings, Bearing steel rolling mlement. It primarily bears Radial, Its dynamic radial rated load is approximately 455000 N, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
540268A bearings ( 70 mm x 160.02 mm x 90 mm) have the advantages of High rigidity, high load-bearing capacity and precision retention, and are therefore widely used in the Backing for multi-roll mills.

The 540268A Backed bearings primarily consist of an inner ring, an outer ring, single-row, double-row, or triple-row cylindrical rollers, and a cage. The outer ring is exceptionally thick, and the rollers and raceways feature a logarithmic profile design to optimize load distribution and reduce edge stress.
Backed bearings possess extremely high load-carrying capacity, capable of withstanding heavy loads and impact loads, while exhibiting low friction, minimal heat generation, and a long service life. The outer surface of the outer ring also utilizes a logarithmic profile, reducing edge loads during operation and improving operational reliability.
