The G-KRR Series wide-inner-ring ball bearings are the same as the RR Series and have a provision for relubrication. They are designed especially for extremely dirty or wet conditions. These bearings feature R-Seals with flared lips which firmly contact the ground O.D. of the inner ring to provide a positive seal against dust, dirt. and other contaminants while effectively retaining the lubricant. G-KRR Series bearings are equipped with Shroud-Seals which provide extra effectiveness and protection.
The extra wide design provides additonal shaft support and extra large grease capacity.
