Car Owners Want Simple-to-Install Center Bowl Liners That Perform Well Without Breaking the Bank
Car owners utilize many different styles of center bowl wear liners on their rolling stock. Some choose full-bowl liners made from manganese steel or molded plastic, while others install a combination of welded vertical rings and horizontal wear plates.
Non-metallic materials used in the demanding center bowl area generally have a short service life leading to frequent replacement, especially on poor performing cars. Manganese steel liners are expensive and tend to work harden causing the material to become more brittle and prone to cracking. It also contributes to developing surface hardness values that often exceed that of the center plate and bolster bowl surfaces they are intended to protect. Weld-in vertical wear rings require extensive labor to install and historically demand greater car shop time to repair and replace cracked welds and liners.
SOLUTION:
Long-Wearing Drop-In Liners Provide Superior Service Life and Reduce Maintenance & Operating Expenses
Pennsy introduces a new AAR-approved full bowl liner offering the advantages of high performance durability and easy drop-in installation, all at a reasonable cost.
The Pennsy Durabowl ST has been shown to perform well below AAR-specified limits for maximum turning force and turning moment. It offers the fast and easy installation of a drop-in liner and the longevity of manganese at a fraction of the cost.
Greater reliability and lower costs for installation and maintenance increase the potential for longer term savings when compared to welded ring and horizontal plate combinations.
Results:
Performance equal to or better than manganese at a fraction of the cost
More durable than plastic bowl liners
Lower installation and downstream repair costs than welded ring and plate combinations
AAR-approved
Simple Drop-in Installation
No welding or tools required to install or replace full bowl liners
Eliminates additional labor costs assoicated with repairing and replacing welded ring vertical liners ~22% savings
Decrease car out-of-service time with faster installation and replacements
 
Durable Steel Contruction
Longer lasting than plastic liners
Less brittle than work-hardened manganese components. Resists premature fracture failure
Durabowl ST is designed to protect center plate and bolster surfaces as opposed to contributing to thier premature wear
 
AAR Approved
Meets or exceeds all AAR requirements for wear and turning resistance
Works with standard lubrication practices
