Deep-groove geometry for high speeds and supporting both radial and axial loads Rubber seals on both sides of the bearing keep the lubricant in and contaminants out Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision Chrome steel for durability and resistance to deformity under heavy loads Pressed steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise SpecificationsClearance           C0 (Normal)Bore Size d         25 mmFeatures             Contact SealsBearing Type      Standard DGBBWeight                0.080 KgDimensionsOutside Diameter D           47.000 mmOutside Ring Width B        12.000 mmRadius Rs min                   0.600 mmBasic Load RatingsCr - Dynamic Load Rating       10.1 kNC0r - Static Load Rating           5.8 kNFactorsGrease Reference Speed         14000 rpmOil Reference Speed                21000 rpm
