Deep Groove Ball Bearings are one of the most widely used rolling bearings and feature small friction and high-limit speed, making them cost-effective and requiring little maintenance. Manufactured from Chromium Steel (GCr15) and heat-treated, these bearings offer high and uniform hardness, as well as good wear resistance, making them suitable for a wide range of industrial equipment, micro motors, small rotary motors, office equipment, and more.

There are two main types of bearings: Shielded (Designation Suffix Z/ZZ) and Sealed (Designation Suffix RS/2RS). Shielded bearings are designed for high-speed applications and provide protection from dirt and debris, while Sealed bearings, made of sheet steel reinforced with nitrile butadiene rubber (oil- and liquid-resistant), have a lower speed limit than Shielded bearings.

The Shielded bearings offered are of the Double Sealed type, with the inner race and outer race made of Chrome Steel (GCr15) and the cage made of Stamping Steel. These bearings have an Accuracy Class of P0 (ABEC1) and a Noise Level of Z1.

The specific bearing model is [Size] - FR188-2rs ABEC1 Bearings, with an Inner Diameter of 1/4", Outer Diameter of 1/2", and Thickness of 3/16". The Flange Diameter is 13.9mm, and the Flange Thickness is 1.1mm.

The Chrome Steel (GCr15) races of these bearings offer high hardness and great wear resistance, which helps to extend the bearings' service life. Additionally, the rubber sealing on both sides of the bearings makes them oil- and liquid-resistant, contributing to easy maintenance and a Z1 noise level suitable for most general use.

These bearings are commonly used in a variety of applications, including glider/rocker arms, wheels of carts, lawnmowers, printers, motors, gearboxes, reducers, textile machinery, and electronic equipment.

In summary, please refer to the provided picture and select the appropriate type of bearings (Sealed or Shield on BOTH or SINGLE side) before placing your order. The suffix on the bearing is solely for differentiating between Sealed and Shield types and will not affect the use of our product.
