DESESIIGNDEVELOPVELOVERDELIELIVERReputation Built on InnovationSince its inception over sixty years ago, the nameSEALMASTER has been synonymous with industryleading product innovation and application-focusedsolutions. With its original platform, born out of theworld’s most demanding environments, the Gold Linelist of features remain, to this day, the pinnacle by whichall other designs are measured. From the verybeginning, employees have built a solid foundation ofcontinued innovation by working with andunderstanding the specific needs of contractors,processors, and key equipment manufacturers aroundthe world. This working relationship has allowed us toDesign, Develop and Deliver tailored bearingsolutions one application at a time.Application Engineering SupportTo support its broad and evolving customer base, SEALMASTERrelies on its experienced Application Engineers (AE) specializingin specific industries and mounted bearing designs. Whencontacted, each AE reviews application parameters, environmentalconditions, and business requirements before recommending asolution. In some cases, depending on the nature of the application,the AE may choose to construct an original and unique bearingdesign specially manufactured to meet the customer’s precisespecifications.Technical Customer ServiceWorking in tandem with Application Engineers are theTechnical Customer Service Representatives. TheTCSR group assists customers with broad basedtechnical inquiries ranging from product nomenclatureand interchanges, to grease and dimensionalspecifications.Electronic Technical SupportIn addition to these departmental resources, EPT also offers avariety of e-commerce solutions designed to improve businessefficiencies and productivity. Some of these solutions include:Product Selection Tools, Electronic Product Catalogs, ProductInterchange Guides, 2D and 3D CAD Downloadable Templates,and an extensive Electronic Media Library.4

DESESIIGNDEVELOPDEVELVELODELIVERDELIVERThousands of Combinations.CUSTOMSELECT 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 otherenvironmental issues. Our engineers realize that bearing applications vary widely in severity, operating parameters,and maintenance regularity. In fact, most applications are not ideal, thus bearings are usually replaced for reasonsother than general fatigue.When your application is challenging enough to demand more than a standard bearing, you literally have thousandsof configuration options with SEALMASTER brand bearings. By modifying component attributes such as lubricationtype, internal radial clearance, seal selection, and housing fit, engineers can optimize system uptime and equipmentperformance.Gold LineGold Line Platform Proven Performance for Over 60 Years Felt Labyrinth SealsERFORMANCE Solid Cast Iron Housing 120 Set Screw PlacementITHOUT Zone Hardened Inner Race 2-3 Misalignment CapabilityOMPROMISE Expansion Designs Available Unique Land Riding Brass Retainer Exclusive Lock Pin and Dimple System Black Oxide Coated - Wide Inner and Outer Races Locking Options: Single/Double Set Screw,SKWEZLOC Concentric CollarPWCCUSTOM SELECT Application Specific Designs High Speed Applications: HSAir Handling Applications: CXU, HTALow Drag Requirements: LO, XLOLow Temperature Applications: LTHigh Contamination Environments: DRTGrease Fitting Options: CSK, CTJ, CSJ, WHigh Temperature Applications: HT, HTC,HTA, HI Other Additional Applications: See Page 17CUSTOMSELECT .Ready to Ship in 9Days or Less ** For Quantities Over25 PiecesConsult EPTCustomer ServiceEngineered Custom Designs Special Housing/Bearing Dimensions- Units built to match your machinerequirements- Tolerances controlled to your application Unique Components Matched To YourApplication- Provides performance enhancements- Designs that solve problems Integrate multiple Machine Elements IntoUnitized Bearing- Ease of assembly- Reduction of components, inventory, andvendorsFlexibleManufacturingProcesses forAlmost AnyModification!5

Contamination erodes standard seals, enters the bearing cavity, and creates indentations in the raceway.These indentations become stress concentration points which decrease bearing life. In extreme conditions, thecontaminants fill the internal cavity and prevent the bearing from rotating. Foreign material prevents the greasefrom adequately lubricating the raceways and balls. These conditions lead to shortened operational life and frequentbearing replacement. The DRT seals utilize a unique multiple-component design that outperforms common multi-lipmolded designs in harsh applications. The 100% grease fill, along with the standard increased capacity of the wideouter race design, allows greater protection against foreign material entering the bearing cavity.High contamination bearings are used on: Agricultural Equipment Aggregate Conveyors Foundry Equipment Bulk Powder Conveyors Construction Equipment8

Typical applicationswhere roller drag can be an issue include cutting, heating, drying, folding, stacking, and finishing. XLO modifications are suited for minimum drag which is approximately 10% of the standard felt seal drag.

Fans and blowers frequentlyoperate at higher speeds than typical industrial equipment and must operate with low noise levels. All Air-Handlingbearings have honed raceways and go through a two-stage noise test verification procedure for quiet operation.The effects of speed and vibration on fan and blower applications can significantly reduce bearing and fan systemlife. SEALMASTER SKWEZLOC locking system maintains ball path roundness and centers the shaft in the bore,reducing noise and vibration in the system. To improve bearing alignment, even in lightweight frame applications,CXU and HTA units are equipped with controlled air handling housing fit. Bearings with contact seals typically resultin higher drag and can add to the energy costs of the system and reduce bottom line profits.
