Description
Deep groove ball bearing is a kind of the most common rolling bearing. The basic type of deep groove ball bearing is composed of an outer ring, a ring, a group of steel ball and a group of retainers. Deep groove ball bearing has a single row and double row two types, and also has sealed bearing and open bearing, open refers to the bearing without sealing structure,sealing type deep groove ball into the dust seal and oil seal. Dust seal cover material for steel plate stamping, plays only a simple prevent dust from entering the bearing raceway. Oil proof type contact type oil seal, can effectively prevent bearing grease inside the spillover.
VCD's 608 and 6203 ball bearings are widely used in booster pumps.Deep groove ball bearings are particularly versatile.They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes.
