TNA (Two-Row Non-Adjustable)

TNA (Twin Row Non-Adjustable) Features and Benefits:

High load carrying capacity
TNA (Twin Row Non-Adjustable Bearings) can withstand heavy radial and axial loads. The inner ring narrow face extends to the abutment, eliminating the need for a separate inner ring spacer.

Axial load in both directions
Tapered roller bearings position the shaft in both directions with a specific axial clearance or preload.

high stiffness
TNA (Twin Row Non-Adjustable Bearings) high stiffness double row tapered roller bearings provide a rigid bearing arrangement.

low friction
The optimized roller design and rib surface finish on the TNA (Twin Row Non-Adjustable Bearing) rib promotes the formation of a lubricant film that reduces friction. This also reduces frictional heat and rib wear. In addition, the bearing maintains better preload and reduces noise levels during operation.
