The Z-549722.WGTR 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.
