Step 5
Insert screws into the remaining mounting holes.
Rotate the RESA ring, measuring the radial displacement at all
of the screw locations.
Tighten the screw with the lowest radial displacement so that it
matches the average radial displacement, whilst ensuring the
maximum torque specified in the table is not exceeded.
Again, rotate the RESA ring and re-check the radial displacement
at all of the screw locations, tightening the screw with the lowest
radial displacement so that it matches the average.
Repeat this process until the radial displacement at all of the
screw locations is within ±3 µm and that all screw torques are
within the specified range.
Excessive tightening of screws can have a small effect on accuracy.
Please contact your local Renishaw representative for more details.

Remove the protective film from the surface of the RESA
Clean the mounting faces of shaft and RESA as
‘Storage and handling’ on page 5
NOTES:
Do not lubricate the screws
Do not use a thread locking compound
Ensure that all screws are tightened to 1.6 Nm
Minimum thread engagement is 6 mm
Recommended screw type is M3 × 0.5 and must comply
with: ISO 4762/DIN 912 grade 10.9 minimum/ANSI B18.3.1M
