About Sealmaster SPM-27 CXU Pillow Block Ball
This Sealmaster SPM-CXU series non-expansion-type ball bearing pillow block with cast iron housing, set screw locking collar, felt seals, and a reduced housing clearance fit for quieter operation in air handling applications. The cast iron bearing housing has a flat square foot with two bolt holes to help accurately align the housing and the insert is rated "medium duty" for applications with moderate combined radial and thrust loads. A lock pin and dimple system provides a direct path for lubrication into the bearing, and prevents outer ring rotation within the housing. The bearing insert is black oxide coated for corrosion resistance and has a wide outer race with a land riding retainer that spaces the ball bearings for even load distribution and prevents contact to reduce friction, vibration, and noise. A collar extends from the bearing inner ring and two set screws spaced 120 degrees apart lock the collar and bearing onto the shaft for a three-point contact hold. This single-row bearing allows self-realignment and compensates for static and dynamic alignment errors up to two degrees. Low friction felt seals retain lubricant and protect against contamination that would shorten the bearing life. This ball bearing pillow block is suitable for use in industrial and commercial air handling applications such as fans and blowers.Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking d
