Notes about B....EL Series :
The extended inner ring design removes the need for extra locational spacers. Additionally, the inner ring bore is relieved to minimize bending stress. These bearings come in both open and sealed versions, and are offered in inch or metric sizes.
Other salient points to be noted :
• Outer rings of bearings size 72 and above are double fractured (suffix-9L).
• Bore dimensions apply after MoS2 coating. All other dimensions are before coating.
• Ultimate static and impact loads should not exceed 150% of catalog ratings.
