SNT LUBRICATIONTimken plummer block housings are designed for grease lubrication. They also can be modified toaccommodate oil-bath and circulating oil- or oil/air-mist systems. Contact your Timken sales engineerfor assistance. Please reference the installation guides on pages 101-105 for grease fill information.Lubrication groove and holes may be provided in the bearing outer ring. This feature, designatedby adding suffix W33 to the bearing number, should be specified whenever re-ordering bearings forpillow blocks. For bearings with lubrication groove and holes, it is suggested that the fresh lubricantis fed directly to the center of the bearing between the rows of rollers and distributed to the rest ofthe bearing. This helps ensure the used lubricant is purged from the bearing. Housed units featuremultiple dimples that can be used to drill and tap for alternative grease fitting locations as needed.
