The dual-lip KRR seal design provides excellent protection against moisture, dust, and debris — a critical feature for agricultural bearings used in planters, grain drills, disc openers, and press wheel assemblies. The parallel outer ring profile allows direct housing mounting without a spherical seat. This bearing is an OEM-style replacement suitable for a wide range of ag equipment applications.
