Fits : CAT 247 , 247B , 257 , 257B. GREASEABLE Bearing Sprocket Group Complete. Includes: Flang Unit, Bearing, seal, seal cover, snap rings and outer dust cap. Factory bearing sprocket groups have an unknown life span since there is no way to add lubrication to the bearing.
When the bearing fails, it will destroy the bearing and possibly the stub shaft on the drive. Bair's Greaseable carrier has a grease fitting installed on the back side of the flange and is cross bored to let grease enter the bearing. It also has Bair's purgeable seal. Grease can be pumped until it purges out of the seal. This allows any contaminants that may have found their way into the bearing to be pushed out as new grease enters, extending the life of the bearing.CAT 247/257B, B2, B3, D and 267/287/277 & B models.
