Bearing alignment device for pillow blocks

An alignment and sealing device for aligning and sealing a shaft in a split self-contained bearing housing unit including means for securing together the split housing members;

• bearing means in said housing unit;
• a shaft generally supported by said bearing means in said housing unit, wherein each of said split housing members has at least one opposing radial groove therein;
• said alignment and sealing device comprising:
• a rigid circular member surrounding said shaft;
• at least two alignment elements axially displaced and radially positioned inwardly on said circular member and firmly abutting said shaft;
• at least one outwardly radial projection on said circular member having a predetermined axial length less than the groove in said housing and having a radial length less than the depth of said groove in said housing, said projection fitted in said groove;
• said circular member having sealing means attached thereto and, radially surrounding shaft;
• a plurality of resilient means fixed to said projection and having a frictional fit with the sides of said groove, said resilient means permitting axial and radial rotational movement of said housing unit relative to the axial and radial center point of said bearings when said housing units are secured together, thereby facilitating misalignment of the housing to the center line of the shaft and bearing.
