EZO 688-2Z (628/8-2Z) deep groove ball bearing

Product detailed description

EZO bearing 688 2Z - non-separable single-row radial ball bearing with a steel cage guided by balls with a non-contacting sheet metal seal on both sides and normal radial clearance. The cover plates of the 688-2Z bearing are pressed into grooves on the outer ring and fit against the smooth inner ring. The 688 ZZ bearing is designed for mounting with a rotating inner ring and is filled with high-quality lubricant with a temperature range from -40 °C to +100 °C for the entire service life of the bearing. If the outer ring rotates, lubricant may leak at higher speeds.
The EZO 688-2Z bearing is marked by the manufacturer SKF as a 628/8-2Z bearing and by CX as 618/8 ZZ
