Product description
This Sealmaster ERX-XLO Series ball bearing insert with Skwezloc concentric locking collar and extra low friction felt seals is suitable for use in mounted bearing housings where bearing friction is a large concern, such as in printing equipment. The outer bearing surface has a snap ring that sits in a groove to locate the insert within its housing. This bearing insert is made from ASTM International 52100 high carbon steel and its rings are coated with black oxide for corrosion resistance. The bearing insert has a heat treated inner race for wear resistance and an outer race with a brass land riding retainer that spaces the ball bearings for even load distribution and prevents contact to reduce friction, vibration, and noise. Lubrication grooves and oil holes in the outer bearing ring feed oil through the bearing and a tapered race profile allows lubricant to more easily flow back into the raceway. A collar extends from the bearing inner ring and a Skwezloc concentric locking collar clamps the slotted collar and bearing onto the shaft. This non-expansion-type bearing allows self-realignment and compensates for static and dynamic alignment errors, has an operating temperature range of -30 to 100 degrees F, and has X-Tra Lo Drag very low friction felt and flinger seals to retain lubricant and protect against contamination that would shorten the bearing life. This ball bearing insert is suitable for use in carrying shafts with radial and thrust loads in printing and packaging applications, such as in web presses and plastic film processing equipment.

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 device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.
