Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread. The raceway grooves on both the inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to radial loads, axial loads can be imposed in either direction. Because of their low torque, they are highly suitable for applications where high speeds and low power loss are required.
In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
High quality steel – Ultra pure steel that increases a bearing’s life by up to 80%
Advanced lubrication technology – Grease developed by NSK are able to increase time and performances of the lubrication
High grade balls – Quieter and more consistent operation at higher speed
Raceways – Designed to minimise running noise and to improve lubricant distribution and longer operation life
Patented seals – Provide resistance to contamination in the toughest environments
Cages – Several types of cages are available to satisfy every application demand
Guaranteed quality – Quality of the ball bearings is 100% guaranteed due to the numerous tests NSK makes
