17 Sensor bearing units
Roller encoder Sensor technology

units SKF roller encoder units use similar sensors
as SKF motor encoder units (page 988)
They provide two signals, which can be used
SKF roller encoder units (ig. 18, table 3) are to determine relative position, speed, accel-
plug-and-play sensor bearing units eration and direction of movement The
designed for applications with outer ring requirements for the receiving interface are
rotation the same as for SKF motor encoder units
The encoder units:

• incorporate a sealed 6201 SKF Explorer
deep groove ball bearing, which is lubri-
cated for the life of the bearing
• can be easily integrated into pulleys, cams,
17 rollers, or wheels to provide a compact
outer ring rotation encoder assembly
• can be supplied, on request, complete with
customized gears, wheels or pulleys
