No I don't think it is, the "nut" unit is well lubricated during manufacture and I'm not aware of any maintainance lubrication requirements.  What they 
are sensitive to is dirt on the track - you need to shield them from dust, swarf, and so on, or they will start to jam as the balls try to roll over the 
contamination.  If you can afford it, and can stop them picking up dirt, they are an excellent solution to producing linear motion from rotary, 
accurately.
