Limitations
•
When in use, the seals can absorb radial swing of the shaft. This depending on the
shaft diameter, in combination with the actual shaft revs/min, this will vary.
•
The maximum radial dynamic movement of the shaft is to be not more than 0.4
mm.
•
If during operations a shaft will frequently swing more than 0.4 mm, a serious
alignment problem has shown up and immediately repairs are required. The shaft
may exceed marginally bigger radial movements during manoeuvring at lower
speed.
•
When the shaft is NOT running, a maximum bearing clearance of 1% will still keep
the seals tight (see instructions wear down measurements)
•
The seals can take no higher speeds then 14 m/s.
•
The maximum standard operating temperature is 80 degrees Celsius.
The maximum run out, measured on the liner, is to be less than 0.05 mm
