Specification Brand : uxcell BulletPoint1 : Size: Model: R188; Dimension: 1/4" x 1/2" x 3/16"(Inner Dia*Outer Dia*T) BulletPoint2 : Chrome Steel Material: Deep groove ball bearings are made of quality chrome steel with excellent strength, hardness, wear resistance and corrosion resistance. It can withstand significant radial and axial loads, providing reliable support in a variety of applications. BulletPoint3 : Features: This ball bearing has a P0 (ABEC1) accuracy class and is suitable for most general purposes. Z1 noise level produces low noise during operation and is suitable for applications requiring a quiet working environment. BulletPoint4 : Grease Lubrication Method: This bearing uses grease as the lubrication method, which can provide a lasting lubrication effect during bearing operation, reduce friction and wear, protect the bearing, and extend the maintenance cycle. BulletPoint5 : Wide Application: widely used in high-speed rotating equipment, such as motors, fans, rollers, etc., as well as household appliances and office equipment. In addition, since the lubrication method is grease, the bearing is also suitable for some equipment where conventional lubrication is impossible or inconvenient, providing long-term and reliable lubrication.
