Feature:

• Single-row, pre-lubricated, normal accuracy.
• Deep Groove Ball Bearings are one of the most widely used rolling bearings.
• With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance.
• Chromium Steel (GCr15) made with heat treating, provides high and uniform hardness, good wear resistance

Selecting Guide:

• Shields (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris.
• Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than Shield Bearings.
