Product Description

Chrome rollers and needle rollers are widly used becaue of their properties as below:

 
 
High hardnessHRC60-66. This allows chrome steel balls to withstand heavy loads and resist wear and deformation.
Dimentional PrecisionThe material properties enable the chrome steel balls good finishing surface and dimentional precision. Based on high pricision, the noice of the bearings can be very low, even silent. 
Low coefficient of frictionChrome steel balls have a low coefficient of friction, which means they can move smoothly and efficiently without generating excessive heat or wear.
Wear Resistance Chrome steel balls maintain their size and shape well over time, even under high loads or in extreme temperatures. This makes them a reliable choice for long-term use in industrial applications.
