Timken® Double-Row Non-Adjustable Industrial Tapered Roller Bearing (TNA)
Timken® Double Row Tapered Roller Bearing
Timken double-row non-adjustable (TNA) bearings feature extended inner race narrow faces that eliminate the need for a separate inner race spacer. This innovative design reduces assembly time and complexity, making it ideal for high-performance machinery. Supplied with an in-built clearance to give a standard setting range, these bearings provide a solution for many fixed or floating bearing applications in sectors such as manufacturing, mining, construction equipment, and power transmission systems.
