description
- The heavy series R-seals wide inner ring bearings are similar to the standard series but are capable of withstanding continuous, heavy or shock loads. The GN-KRRB series has heavier section 300 series bearings, as well as a considerably thicker sealing member in the contact-type diaphram seal. This design ensures complete retention of the lubricant and positive exclusion of all contaminients. These bearings are especially effective at slow-to-moderate speeds under the severest of conditions of dirt and corrosion.
