The taper shape of the rollers means they offer a larger contact patch with the raceways, which results in increased load-carrying capacity compared to spherical roller bearings The taper shape of the rollers means they offer a larger contact patch with the raceways, which results in increased load-carrying capacity compared to spherical roller bearings
The bearings are designed with a special coating that reduces friction between the moving parts, resulting in increased efficiency and reduced energy consumption The bearings are designed with a special coating that reduces friction between the moving parts, resulting in increased efficiency and reduced energy consumption
Its standard clearance class is CN (normal), which is suitable for applications where there's no significant temperature variation or constant operating speed Its standard clearance class is CN (normal), which is suitable for applications where there's no significant temperature variation or constant operating speed
A wider bearing provides more surface area for the lubricant to spread, reducing friction and wear A wider bearing provides more surface area for the lubricant to spread, reducing friction and wear
