610627B Bore 55 Mm, Backing Bearings For Cluster Mills
The 610627B 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 610627B bearing is a Backing bearings for cluster mills with an inner diameter of 55 mm , an outer diameter of 120 mm, a width of 26 mm. It typically uses P4 (ABEC 7) grade precision tolerances and GCr15SiMn rings, GCr15SiMn rolling mlement. Its dynamic radial rated load is approximately 57860 N, its static radial rated load is approximately 96930 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
610627B bearings ( 55 mm x 120 mm x 26 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 610627B 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.
