Railway Application
The BT1-1125 bearing is suitable for consideration in railway and heavy-duty applications where the specified tapered roller bearing configuration is required. Selection should consider radial and axial loads, shaft and housing dimensions, speed, lubrication, mounting arrangement and operating temperature. For railway spare-part replacement, buyers should match the complete bearing designation and drawing rather than relying only on d and D.
