Sealmaster® ER Style Ball Bearings
1 / 10Pages

Performance Cylindrical OD Bearings (ER) Sealmaster ER Style Ball Bearings Sealmaster Gold ER bearings feature a cylindrical OD and snap ring for easy installation in a roll assembly. Shaft lock is achieved by either setscrew or Skwezloc® concentric locking collar. The felt seal with flinger provide a good balance between contaminant entry, GoldPlex HP™ grease loss and friction. Depending on your preference, these bearings are available in both inch and metric shaft sizes with a wide variety of sealing and lubrication options or ERX-TREME industry specific solutions as illustrated on the pages to follow.

Performance Cylindrical OD Bearings (ER) Features and Benefits Outer Race With Tapered Lands The Sealmaster ER Bearings Outer Ring is black oxided and comes standard with a locating ring and lubrication groove and lubrication inlet. In addition, they have the Sealmaster patented Tapered Lands bearing race profile which means that critical lubricant is circulated more efficiently, while requiring no regular service intervals. The outer land surface in a conventional bearing is parallel to the axis of the inner ring. The Tapered Lands surface is tapered in a radial direction toward the...

Performance Cylindrical OD Bearings (ER) Features and Benefits continued Multiple Locking Methods Setscrew Locking 120° spaced, balanced three point contact minimizes inner ring distortion vibration, reduces noise, and improves reliability. Precision manufactured diamond faceted setscrews contribute to improved clamping and resistance to back out. Sealmaster Skwezloc® Concentric Locking Collar SKWEZLOC is a concentric locking collar clamp design that results in nearperfect concentricity of the shaft to the bearing bore and maintains near perfect ball path roundness, while reducing fretting...

Performance Cylindrical OD Bearings (ER) Options Bearings are typically selected using L10 fatigue life calculations based on ideal operating conditions. However, most bearing problems are not fatigue related, but occur due to contamination, lubrication starvation, or other environmental issues. As a result our Bearing engineers have developed custom solutions to meet the varying severity, operating parameters and maintenance regularity, such as ERX-TREME and Custom Select. * The following trade names, trademarks and/or registered trademarks that follow are used in this material by Emerson...
