Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * SKF provides six varieties of clearance or preload. Check with your distributor before specification in applications, CB and GA variations are the most widely stocked. Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Special SRACBB: problem solver for applications with large thrust loads in one direction See literature for details Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Capable of Radial Loads, double directional thrust loads, combined loads Available with shields, seals, and snap rings Economical compact design Can operate at high speeds **Reminder: This bearing is designed primarily for axial loads.** Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Same size as standard 53 and 33 series double row ACBB More thrust capacity (40° angle of contact) ABEC 3 tolerances, Machined brass cage, “CB” axial internal clearance Split inner ring allows extra balls and more robust cage 5 sizes presently, all come with snap ring which can be removed if not needed Ball Bearings 2 - * Ball Bearings 2 - * Can handle Thrust Loads in both directions and some Radial Loads Eliminates the need for an additional thrust bearing Great for limited space applications Must be paired with radial bearings for handling large combined loads Ball Bearings 2 - * Ball Bearings 2 - * **Reminder: This bearing is designed primarily for axial loads.** Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Ball Bearings 2 - * Sizes less than 04: 00 = 10 mm 01= 12 mm 02 = 15 mm 03 = 17 mm Over 480 mm, a “/” is used: for example: 619/560 Conrad assembly method is used in SRDGBB. The outer ring is distorted briefly during assembly to allow the introduction of additional balls. Ball Bearings 2 - * Metallic shields (2Z) Fair grease retention Lowest
