âž” fig ). If it is anticipated that bearing relub-rication will be necessary during opera- tion,the band should be removed before the bearing is mounted.Whenrelubricating, grease should be slowly pressed into the bearing as it rotates until fresh grease emerges from the sealing lips. Excess pressure should be avoided to prevent industrial seal damage. page 54

Recommendations Relubrication of sealed SKF spherical roller bearings The sealed spherical roller bearings shown in the product tables ( onwards) have an annular groove and three lubrication holes as standard. To prevent moisture from penetrating and to retain the grease in the bearing a polymer band in the groove covers the lubrication holes (
