PRODUCT DETAILS
The basic designs of single row deep groove ball bearings are open and sealed. For manufacturing reasons, open bearings of the same size as sealed or dust-proof bearings may also have seal grooves in the outer ring. Bearings with shields or seals on both sides are maintenance-free, lubricated for life. Such bearings cannot be cleaned and the temperature cannot exceed 80 degrees Celsius.
