Part Number Example

INCH - PART NUMBERING SYSTEM
112 NU 80
BORE TYPE LENGTH LENGTH IN 1/16 INCH
        NU or NX = Inch Bearing
FNU = Flanged Inch Bearing
        BORE IN 1/16 INCH
Examples:
12 NU 80 = 7 inch x 5 inch NU Bearing
24 FNU 32 = 1 1/2 inch x 2 inch NU Flanged Bearing
METRIC - PART NUMBERING SYSTEM
MB 150 100 NX
TYPE BORE LENGTH LENGTH IN MM
        BORE IN MM
        MB = Metric Bearing
FMB = Flanged Metric Bearing
Examples:
MB 150 100 NX = 150 mm x 100 mm NX Bearing
FMB 06 04 NU = 6mm x 4mm NU Flanged Bearing
