Description

NACHI Super Precision Ball Bearing, Screw Support, Series: TAB, 50 mm Bore, 100 mm OD, 1 Row, 20 mm Width, Open Closure, 69.5 kN Dynamic/119 kN Axial Load, Steel Bearing, Polyamide Cage, 2700 rpm Grease/3500 rpm Oil Maximum, 250 deg F

Features:

• Seal is integrated into a ball screw support bearing with great axial rigidity
• Maintenance-free because high performance grease is pre-filled (prevents entry of foreign substance from outside)
• Preset preload for easy installation onto the machine
• With plastic cage, more balls are incorporated than conventional angular contact ball bearing to increase rigidity
• Energy saving thanks to excellent low starting torque and rotational torque
• Contact type seals with excellent sealing performance and non-contact type seals with reduced torque loss and temperature rise

Applications:

For high speed precision machine tools and precision measuring instruments and precision feed actuators such as robots

Standards/Approval:

• ECCN: EAR99

Warranty:

1 year
