• Single row, ball, externally self-aligning, extra light duty
• PTFE seals and CRES sealcaps
• Exposed surfaces except bore, caps, and seals are cadmium plated

These bearings are designed to compensate for initial misalignment
• Also offered with CRES 440C material and/or zinc nickel plating per OEM specifications
