They are actually called "ball transfers". They are a single large steel ball riding on a bed of smaller recirculating steel balls. Some are environmentally sealed, others are not. Non-sealed ones, in a dirty wet environment will get crunchy and eventually lockup. The ones I'm familiar with cannot be opened up and serviced. They are a throw away item.
