High Capacity. Long Life. Minimum Wear. With more than 30 years of service, the Crown SE™ provides durability, reliability, longevity, and superior car protection, even in the most demanding high-mileage applications. After 2 million miles of service, the Crown SE continues to perform like new.

Heavy-duty protection. Superior energy management. Reduced component wear. Specially designed for extreme heavy-haul operations throughout the world.

Light weight. High performance. Proven reliability. Just a few reasons why the Miner TF-880™ is the most widely specified gear in the industry. And the only friction elastomer gear with over 30 years of experience and more than 1 million units in service.

Designed for maximum hunting control, the TCC-III-LT high-performance side bearing also provides superior curving performance and increased set-up height tolerance. 1. Simple 3-piece design makes these side bearing easy to install and maintain 2. 5/8" travel from 5-1/16" set-up height, or 1" travel from 5-7/16"set-up height. Solid height of 4-7/16" 3. Additional travel improves curve negotiation 4. Unique top cap design controls rotation and tipping

The TCC-IV long travel constant contact side bearings feature a more durable, heat-resistant design to maximize the life of your side bearings under the most demanding high-speed, high-mileage applications. 1. Housing vents and insulators provide superior heat dispersion, increasing the life of the side bearings. 2. Anti-rotational lugs improve rotational resistance and maximize energy absorption, resulting in higher hunting thresholds. 3. Patented TecsPak springs provide excellent vertical energy absorption for car body roll control. 4. Color coded insulators for quick identification. 5. Simple 3-piece design makes these side bearings easy to install and maintain. 6. 5/8" travel from 5-1/16" set-up height. 7. TCC-IV side bearings allow railcars to run at higher speeds with reduced truck and wheel wear.
