5.7 The equipment must be earthed to prevent sparks due to static electricity discharge.
Shaft runout should not exceed 0,05 mm (.002”) TIR (Total Indicator Reading) at
any point along the shaft for ball or roller type bearings. For sleeve type bearings,
refer to manufacturer instructions. If the equipment is not completely
dismantled, verify runout near seal location.
The above values apply to shaft speeds in
the range from 1000 to 3600 RPM. For
values above and below, consult your
Flowserve representative.
See figure 1.
Shaft endplay should not exceed
0,25 mm (.010”) TIR, regardless
of thrust bearing type.
See figure 2.
Radial shaft movement should be checked against the equipment
manufacturer's specifications. Generally
0,05 - 0,10 mm (.002” -.004”) will be
applicable for ball or roller type bearings.
For sleeve or journal type bearings,
values will generally be in the order of
0,10 - 0,15 mm (.004” - .006”).
See figure 3.
Seal chamber squareness to the shaft centreline should be within
0,015 mm per 25 mm seal chamber bore (.0005" per 1" seal chamber
bore).
Note: make sure that shaft endplay does not affect the reading.
Verify the smoothness of the seal chamber
face for a good gasket joint.
See figure 4.
