514278A Bore 180 Mm, Support Rollers For Multi-roll Cold Rolling Mills, Machined Brass Cage
The 514278A 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 514278A bearing is a Support Rollers for multi-roll cold rolling mills with an inner diameter of 180 mm , an outer diameter of 406.42 mm, a width of 217 mm. special hardening rings, Bearing steel rolling mlement. It primarily bears Radial, Its dynamic radial rated load is approximately 2500000 N, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
514278A bearings ( 180 mm x 406.42 mm x 217 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 514278A 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.
