Can handle light to moderate loads, moderate speed, and vibration. All bearings are equipped with close tolerance metal shields, an internal NBR contact seal (K-type), and factory lubricated with an ISO VG 100 PAO base oil, NLGI No. 2, lithium-stearate thickened grease. They are narrower than the standard duty configuration but have similar capacity. These units are plugged to prevent contamination and cannot be re-greased.
