Product Overview
The 6201 ZZ bearing is a versatile single-row deep groove ball bearing designed for applications requiring reliable radial load support and moderate axial load capacity. This bearing features a ZZ (metal shield) configuration on both sides, providing effective protection against contamination while retaining grease lubrication for maintenance-free operation over extended periods.
Manufactured from high-quality chrome steel (GCr15) with a stamped steel cage, the 6201 ZZ combines dimensional accuracy with consistent performance. With its compact 12 mm bore, 32 mm outside diameter, and 10 mm width, this bearing fits seamlessly into a wide range of mechanical assemblies where space is at a premium.
The deep groove raceway geometry enables the bearing to accommodate radial loads as well as bi-directional axial loads, making it a practical choice for electric motors, power tools, pumps, and various industrial equipment. The ZZ shield design minimizes grease leakage and keeps contaminants out, extending service life in moderately clean environments.

Quality and Manufacturing
Each 6201 ZZ bearing is manufactured to ISO standards using precision grinding and finishing processes. The chrome steel (GCr15) rings and balls undergo controlled heat treatment to achieve optimal hardness and fatigue resistance. Dimensional accuracy is verified against ISO tolerance class P0 (ABEC 1), and radial internal clearance is checked to C0 specifications. The stamped steel cage is securely crimped for consistent ball retention and smooth rotation. Every production batch undergoes load testing and dimensional inspection before shipment.

Frequently Asked Questions
What is the bore diameter of the 6201 ZZ bearing?
The 6201 ZZ bearing has a bore diameter (d) of 12 mm, an outside diameter (D) of 32 mm, and a width (B) of 10 mm, conforming to standard 6200-series deep groove ball bearing dimensions.
What does "ZZ" mean in a 6201 ZZ bearing?
"ZZ" indicates that the bearing is equipped with metal shields on both sides. These non-contact shields protect the internal components from dust and debris while retaining grease lubrication, making the bearing virtually maintenance-free in moderate operating environments.
What is the maximum rotational speed of the 6201 ZZ bearing?
The 6201 ZZ bearing can operate at up to 22,000 rpm with grease lubrication. This high-speed capability makes it suitable for applications such as electric motors and power tools where rotational speeds are significant.
What is the load rating of the 6201 ZZ bearing?
The 6201 ZZ bearing has a basic dynamic load rating (Cr) of 6,800 N and a basic static load rating (C0r) of 3,050 N. These ratings define the bearing’s capacity to support radial and axial loads under rotating and stationary conditions respectively.
What is the difference between 6201 ZZ and 6201 2RS bearings?
The 6201 ZZ uses metal shields (non-contact) for contamination protection, while the 6201 2RS uses rubber seals (contact type) that provide better protection against moisture and finer particles but generate slightly more friction. ZZ bearings are preferred for higher-speed applications, while 2RS suits harsher environments.
What materials is the 6201 ZZ bearing made from?
The 6201 ZZ bearing is manufactured from chrome steel (GCr15) for the inner ring, outer ring, and rolling elements, with a stamped steel cage. This material combination provides good wear resistance, dimensional stability, and fatigue life under normal operating conditions.
