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.

4 The Tapered Lands surface is tapered in a radial direction toward the bearing race. This subtle yet crucial design change allows lubricant to more easily flow back to the raceway. With improved bearing lubricant circulation comes significantly longer bearing service life. This improved circulation and service life comes without any reductions in bearing radial or thrust capacities.* For Bearings that are maintained and relubricated on a regular basis, there isno significant difference in expected and BenefitsSingle Lip Contact SealSingle Lip Contact Seal consists of a nitrile rubber washer in metal shroud to shield the lip from large contaminants. The seal is designed to balance drag and protection in wet and dry environments.

5 This can be specified by adding the suffix C to the part Sealing Options can be found on pages G-103 to Sealing Options Felt Seal With FlingerThe standard felt seal provides a tight labyrinth seal which retains lubrication and acts as a filter to exclude contamination. The external stamping is a flinger which shields the felt from large contaminants and directs them away from the sealing surface. The design operates with less drag and less heat generation than rubber contact Cylindrical OD Bearings (ER)Performance Cylindrical OD Bearings (ER) Mtd. ball BearingsSealmaster Skwezloc Concentric Locking CollarSKWEZLOC is a concentric locking collar clamp design that results in near-perfect concentricity of the shaft to the bearing bore and maintains near perfect ball path roundness, while reducing fretting corrosion.

6 This design eliminates the shaft damage of setscrew locking, and minimizes bearing induced vibration for smoother quieter operation. The collar has a TORX head cap screw that outlasts stripping 12 times longer than hex head cap Locking Methods Setscrew Locking120 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 Hardened Inner RaceSealmaster incorporates a unique heat treat process that hardens the inner race only where it is the ball path. The black oxided zone hardened inner race results in improved lock reliability as a result of less distortion at the setscrew location and improved thread conformity resulting in improved clamping and resistance to setscrew Riding RetainerThe Sealmaster unique land riding metal retainer design provides superior pocket clearance allows for 360 oil circulation around the rolling elements resulting in better retained and utilized lubrication.

8 However, most bearing problems are not fatigue related, but occur due to contamination, lubrication starvation, or other environmental issues.

High temperature bearing with increased radial internal clearance toaccommodate thermal expansion of components High temperature Nomex seal and Krytox*-226 grease Specify as ERX-xx HIYThis may be essential when shafts grow in length due to temperature changes.

10 The single half-dog setscrew has a cylindrical nub that protrudes out of the bottom of the setscrew. The nub is used to mate loosely with a slot milled into the shafting. As the shaft spins, the nub interferes with the slot and positively turns the inner ring. See HIY installation instructions. Note: All expansion Bearings must be used in conjunction with a fixed bearing to stabilize the system.
