RADIAL BEARINGSUltra Light 9300K SeriesThe 9300K Series bearings are designed principally for applicationswhere housing diameters are restricted, and it is desirable to maintainrelatively large shaft diameters. This series resembles the 9100K seriesin that respect except that corresponding sizes of the 9300K series havea somewhat thinner section. Machine tools, textile machinery and jetengine gearboxes are among the application fields in which thesebearings are used extensively.dDCDIMENSIONS – nce 0.0000" 0.000 mmto minustolerance 0.0000" 0.000 mmto ingCotolerance 0.0000" 0.000 mmto 03910.800.363540024020640028500(2)Maximum shaft or housing fillet radius which bearing corners will clear.Also available with two shields.

RADIAL BEARINGSLight 200W SeriesThe 200W Series, maximum capacity type is dimensionally interchangeable with the 200K type but has greater capacity for supporting heavierradial loads and light thrust loads in either direction. Maximum capacitybearings feature a filling slot in the shoulder of each raceway toassemble an extra large ball complement.

RADIAL BEARINGSLight 200 SeriesExtra Width Inner RingThe 200 Series, extra width inner ring type has sizes available both in therubber seal (P) and Mechani-Seal (L) design.A distinguishing feature of this series is the extra width inner ringwhich provides greater shaft support. The “P” seal version utilizes a BunaN rubber contact seal whereas the “L” seal employs a frictionless metallicmember to form a labyrinth.These bearings are used extensively in high speed pneumatic tools,small pumps, electric motors, domestic appliances, etc.These bearings are electric motor quality for applications where extraquietness is a requirement.DIMENSIONS – TOLERANCESBearing NumberBoredOutside DiameterDtolerance 0.0000" 0.000 mmto minustolerance 0.0000" 0.000 mmto minusWidthB1InnerRingOffsetRing Widths 0.000", RatingCoExtendedDynamicLoadRatingCEonesealLone 2830830106014601760345034504700620078001930 86501930 86502450 108003200 143003600 .0150.7870.8271.0241.06320.0021.0026.0027.000.039 0.990.039 003700049000DIMENSIONS – TOLERANCESBearing NumbertwosealsLLBoredtolerance 0.0000" 0.000 mmto minustwosealsNPPOutside DiameterDtolerance 0.0000" 0.000 mmto 30022200290003600037000(1)(4)Maximum shaft or housing fillet radius which bearing corners will clear.Also available as 203KLL with .718" (18.24mm) inner ring width.Also available as 205KLL with .812" (20.64mm) inner ring width.(4)Equipped with “R” seals.(2)(3)26in.Ring Widths 0.000,–.005" 0.00,–.12 mmmmin.lbs.N
