4308 open TN oiled Double Row Deep Groove Ball Bearing
Double row design for higher load capacity. The double row deep groove ball bearing 4308-TN has a considerably higher load capacity than comparable single row deep groove ball bearings, but is only slightly wider.
Features
-
double row design: significantly higher load capacity than comparable single row deep groove ball bearings; additionally, it can support tilting moments
-
narrower than two comparable single row deep groove ball bearings side by side
-
cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
-
medium series with compact dimensions and average weight
-
suitable for very high radial loads and light axial loads in both directions
-
suitable for high running accuracy, quiet running and high speeds
-
seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
-
good fixed bearing property, but can also be used as a floating bearing, each in both directions
