About this item

• [Size] – FR188ZZ ABEC1 bearing (I.D.=1/4″, O.D.=1/2″, Thickness=3/16″, Flange Dia: 35/64″).
• [Durable] – Chrome Steel (GCr15) races offer high hardness and great wear resistance, thus extend bearings’ service life.
• [Load & Speed] – Dynamic load rating of 344N and static load rating of 80N. The limiting speed is 40000 RPM under grease lubricating.
• [Easy to Maintain] – Shields on both sides to keep lubricant in. Z2 noise level for most general use.
• [Application] – Commonly used for glider/rocker arms, wheels of the cart, lawnmowers, printers, pumps, motors, gearboxes, reducer, textile machinery, electronic equipment, and more.

Please refer to the picture and select right type of bearings before your order (Sealed or Shield on Both or Single side of the bearing). Suffix on the bearing just for differentiating between Sealed and Shield type of bearing. It would not affect the use of our product.

Description:

• Single-row, pre-lubricated, normal accuracy.
• Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions.
• 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
• Suitable for all kinds of industrial equipment, micro motor, small rotary motor, office equipment and so on.

Selection 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.
