1. GCAA MANAGEMENT WORKSHOP INCREASED BEARING PERFORMANCE WITH PROPER SHAFT MOUNT AND SEALS

2. Why do bearings fail? A – Lubrication Contamination B - Mounting C - Miscellaneous D - True Fatigue

3. What Seals Do... Keep Contaminants Out Keep Lubricant In Minimize Bearing Failures with the Proper Seal

4. Good Seals Should Operate on hardened and ground surface Not be forced out during relubrication Be easily removed without bearing disassembly Be capable of handling the full misalignment capability of the bearing

5. Clearance Seals  Z-Seal (Rexnord) H-Seal (Link-Belt)  All metal construction  High Speed  Excellent Abrasion Resistance  High Temperature  Full Misalignment Capability  Low Drag Basic Seal Types Z-SEAL H-SEAL  Disadvantages  Fine materials and liquids can pass by seal  Heavy vibration can cause metal parts to wear

6. Light Contact Lip Seals  K-Seal (Rexnord)  High Speed Capable  Contact Lip Seal  Seals against contaminants  Very good in Vibratory applications  Full Misalignment Capability Basic Seal Types K-SEAL  Disadvantages  Seal lip pressure causes higher operating temps  Temp limit of 250° because of Buna-N rubber  Chemicals can affect Buna-N

7. Heavy Contact Single Lip Seal  M-Seal (Rexnord) E-Seal (Link-Belt)  Heavy Contact Seal  Seals against fine materials and liquids  Great for vertical shafts  Full Misalignment Capability Basic Seal Types M-SEAL E-SEAL  Disadvantages  Seal lip pressure results in higher operating temps  Speed is limited  Temp limit 250° because of Buna-N rubber  Chemicals can affect Buna-N rubber

8. Multi Lip Heavy Contact Seal  E7-Seal (Link-Belt)  Heavy Contact Multi Lip Seal  Seals in extremely dirty and wet environments  Metal shield to protect rubber  Great for vertical shafts  Full Misalignment Capability Basic Seal Types E7-SEAL  Disadvantages  Heavy Seal lip pressure results in higher operating temps  Speed is very limited  Temp limit 250° because of Buna-N rubber  Chemicals can affect Buna-N rubber

9. High Temp Heavy Contact Lip Seal  M-Seal Viton (Rexnord)  Heavy Contact Seal  Seals against fine materials and liquids  Great for vertical shafts  Full Misalignment Capability  400° Temp limit  Very resistant to Chemicals Basic Seal Types M-SEAL  Disadvantages  Seal lip pressure results in higher operating temps  Speed is limited

10. Ultimate Sealing Package Auxiliary Cap Seals

11. Seals against liquids and gritty contaminants Effective against water washdown, taconite, cement, sand, or caking build up Safely encloses rotating components Protects primary seal 5 points of protection Advantages

13. Shaft Mounting Systems Comparison

14. SHAFT ATTACHMENTS Single Set collar  Single Set collar  Most Common  Easy to install  Most economical Eccentric Locking  Eccentric Locking  More Holding Power  Accommodates for undersize shafting  Economical Double Set collar  Double Set collar  Increased shaft holding power  Increased Stability  Moderate cost Tapered Adapter Mount  Tapered Adapter Mount  Full 360° shaft contact  Concentric Mounting  Best Running Accuracy  Highest Shaft holding power  Accommodates undersize shafting  MOST DIFFICULT TO INSTALL

16. What if we could simplify and guarantee that your tapered adapter installation was good every time?

17. Installation: ZAF makes it easy! SAF STYLE SPLIT 20 steps ~ 45 minutes ZAF6000 7 steps ~ 5 minutes ZAF is factory lubricated, pre- adjusted and shaft ready Common Installation Errors 1.Set clearance 2.Component alignment 3.Bolt torque 4.Contamination

18. SHŪRLOK Highlights  Break thru Optical Strain Sensing Technology (OSS) For correct installation every time  Proprietary Positive Locking System (PLS)  Fast install  Easy to remove (Built in Puller)  Fits entire Rexnord Housing line including the ZAF (SAF style interchange  Takes the mystery out of mounting

19. Break Thru: Spyglass TM OSS Technology Benefits Indicates when the mount has been properly tightened Signals too loose & too tight Two indicators on lock nut to ensure a proper reading

20. Proprietary: Positive Locking System Alignment Groove Tapered Sleeve Benefits Prevents inner ring fracture in high load & vibratory environments Enables industry leading grip on shaft (13,500 lbs on 2 7/16”) Mounting is no longer limitation of capacity, Enables ease of removal

21. 3 Field interchangeable seal options suits many diverse applications Spyglass™ Optical Strain Sensing Technology provides error free installation Rugged one-piece housing decreases installation/removal time by 80% versus SAF models Roller elements machined to best-in- class tolerance provides longer bearing life Self aligning spherical roller bearing provides 3 degrees of static and dynamic misalignment Positive Locking system provides easy installation and removal, even for undersized shafts. Factory pre-lubricated elements require 80% less lubrication than SAF models - ISO 14000 Friendly! Factory pre-set clearances reduces installation time by 80%! Super-finished raceways provide a cool running, quiet, high speed and high load capacity bearing Hardened Adapter Inner Ring resists fracture under shock and heavy loads Easy installation: Simply tighten collar until the Spyglass shows this color pattern Rexnord SHŪRLOK F& B
