The Bearing housing (OEM Part No. 3128314659) is a spare part compatible with Boomer 281, Boomer-281 and boomer-282 underground drilling rigs. Manufactured from durable alloy steel, it acts as a structural component for the rotary bearing installation assembly at the bearing support housing position. It provides a precise fixed cavity to mount and protect rolling bearings, evenly distributing rotary loads and isolating bearings from external rock debris and impact damage. Its rigid alloy steel shell keeps bearings aligned steadily, reducing abnormal noise and premature failure of rig rotary systems.
