This utility model provides a split-type adjustable bearing housing, belonging to the technical field of bearing accessories. It addresses the problem that existing split-type bearing housings often use straight slot designs for bolt holes, relying solely on clamping force to fix the bolts to the equipment after passing through the holes, which easily leads to lateral displacement after prolonged operation. The design includes a top cover, sliding blocks, bolt seats, anti-displacement components, and anti-loosening components. Two sliding blocks are slidably connected inside the mounting plate; two bolt seats are fixedly connected to the outside of the two sliding blocks; the anti-displacement components are disposed inside the mounting plate; and two sets of anti-loosening components are disposed inside the two bolt seats. This utility model effectively avoids the overall positional displacement problem caused by equipment vibration after the bearing housing is connected. Simultaneously, the mechanical limiting structure of the anti-loosening components reliably constrains the fixing bolts, thereby ensuring that the bearing housing maintains a stable connection with the equipment during long-term operation.
