REXA
Pitch
30 μm
Material
303/304 stainless steel
Coefficient of thermal expansion (CTE)
(at 20 °C)
15.5 ± 0.5 μm/m/°C
Mounting shaft coefficient of thermal
expansion
(at 20 °C)
*
15.5 ± 1 μm/m/°C
Installation temperature
20 ±5 °C
Operating temperature

NOTE:
Angular mechanical safe position =
MSP × 360
π x D x 1000
Where MSP = linear mechanical safe postion (mm) and D = external diameter of RESA/REXA ring (mm)
