Shaft Alignment
Why ?
• Many premature bearing failures are caused by fatigue; a d
result of shaft misalignment
• Significant share of all cost related to machine breakdowns
caused by shaft misalignment
• Shaft alignment is an essential maintenance practice of the
Lifecycle

Shaft Alignment
Shaft misalignment causes:
• Increased bearing load
• Reduction of bearing life
• Increased wear of seals & couplings
• Increased vibrations
• Increased noise
• Increased energy con
• Shaft failures

SKF Shaft Alignment tool TMEA 2
TMEA 2 – main benefits
• One hand operation.
This frees the operator to perform the alignment
• Only 4 buttons for operation
• Display unit shows both “real-time” coupling & feet values

SKF Shaft Alignment tool TMEA 2
TMEA 2 – main benefits
• Magnet brackets allow easy
& quick fixture of the measuring units onto
the shaft. Chain connection also possible.
• “Soft foot” feature is shown on the display
easily guiding the user through this
function

SKF Shaft Alignment tool TMEA 2
TMEA 2 – other benefits
• Laser line combined with the line scale make
pre-alignment easier
• Pre-set machine dimension values facilitate quickdata input
• “Real time” values in both horizontal en vertical
plane makes rechecking of the alignment
unnecessary
