Notes about MBH Series :
Thanks to a thicker inner ring, the BH-L and MBH series can accommodate increased misalignment. These bearings are offered in both open and sealed versions, with options in inch and metric sizes.

Other salient points to be noted :
• Outer rings of bearings size 160 and above are double fractured (suffix-9L).
• All dimensions apply before MoS2 coating and Fracture.
