WGTR 55x120x52 Bore 55 Mm, Back-up Rollers, For Multi-roll Cold Rolling Mills
The WGTR 55x120x52 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 WGTR 55x120x52 bearing is a Back-up Rollers with an inner diameter of 55 mm , an outer diameter of 120 mm, a width of 52 mm. Rolling bearing steel (chromium steel) rings, GCr15SiMn rolling mlement. optional (Gap seal) type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
WGTR 55x120x52 bearings ( 55 mm x 120 mm x 52 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 WGTR 55x120x52 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.
