Reliability. Durability. Low maintenance.

These are key benefits you receive by investing in Miner's high quality railcar components. Backed by exhaustive engineering, research and development, quality testing, comprehensive service analysis and over 115 years of actual rail experience, Miner products are components you can count on.


Miner’s variety of steel-friction and elastomer-friction draft gears provide higher capacity and allow greater payloads for all service requirements. Certified under various AAR M-901 specifications and AAR quality specification M-1003, Miner draft gears provide superior cushioning and increased protection of your railcars.


Constant Contact Side Bearings, featuring Miner's patented TecsPak® elastomer pads, are designed to reduce truck hunting, increase car stability and lower component wear on various types of cars. TCC-IV side bearings, specifically engineered for long-travel applications, are available in various preloads and maintain operation preload under all service conditions. Miner also offers a variety of retrofit kits to upgrade your existing block and double roller side bearings to long travel.


TecsPak® is Miner's patented elastomer spring material that is used in draft gears, constant contact side bearings, and European UIC buffer and drawgear spring applications. TecsPak® absorbs more energy per weight or volume than comparable rubber, urethane, or steel springs. It is extremely durable, resistant to dirt, lubricants, fluids, and most solvents and is maintenance free while in service.


DuraShield™ trough hatch covers, available in both round and square end-cover configurations to accommodate most 24" trough designs are available in all standard lengths. The DuraShield is a lightweight profile cover system that is more durable than fiberglass and lighter weight than all-aluminum hatch covers, providing a more consistent seal in all weather conditions.
