BALL BEARING HOUSED UNITS

KR, KRR, KRRB NON-RELUBRICATABLE TYPES

Designed for extremely dirty or wet conditions. Feature R-seals with flared lips that firmly contact the ground O.D. of the inner ring. R-seals provide a positive seal against dirt and other contaminants, while effectively retaining the lubricant. Equipped with shroud-seals, providing extra effectiveness and protection. Extra-wide design provides additional shaft support and extra-large grease capacity. suggested shaft tolerances:
