6201 ZZ FAG 12x32x10 Ball Bearing

Product Description

6201 ZZ FAG 12x32x10 mm is a single row deep groove ball bearing manufactured under the FAG brand, part of the Schaeffler Group. It has a 12 mm bore diameter, 32 mm outside diameter and 10 mm width. The bearing belongs to the 62 series and features two non-contact metal shields, one on each side. The ZZ designation is commonly used for the double-shielded configuration identified as 2Z in FAG nomenclature.

The double metal shields help prevent larger contaminants from entering the bearing and assist in retaining lubricant within the rolling element assembly.

The deep groove raceway design allows the bearing to accommodate radial loads and axial loads in both directions, subject to the manufacturer's permissible operating conditions.

Unlike contact-sealed bearings, the metal shields do not continuously rub against the inner ring. This avoids the additional contact friction associated with rubber contact seals.

Technical Specifications - FAG 6201 ZZ

Dynamic load rating C, static load rating C0, fatigue load limit Pu, reference speed, limiting speed and bearing mass have not been included because these values have not been independently confirmed for the exact FAG bearing sold under the commercial designation 6201 ZZ.

What Does 6201 ZZ FAG Mean?

6 - Bearing Type

The first digit, 6, identifies a single row deep groove ball bearing.

This bearing design uses balls running between deep raceway grooves in the inner and outer rings.

2 - Dimensional Series

The second digit, 2, identifies the 62 dimensional series.

This series defines the standardized dimensional proportions of the bearing.

01 - Bore Diameter Code

The final two digits, 01, indicate a bore diameter of 12 mm.

ZZ - Double Metal Shields

The ZZ designation is widely used for bearings equipped with two metal shields.

In FAG/Schaeffler nomenclature, the corresponding shield arrangement is designated 2Z.

The shields are non-contact, meaning they do not operate in continuous frictional contact with the inner ring.

Important: 6201 ZZ is a commonly used commercial designation. Before confirming complete equivalence with the specific FAG catalogue designation 6201-2Z, the marking on the bearing or its original packaging should be checked.

Bearing Construction and Operating Principle

The FAG 6201 ZZ bearing consists of an inner ring, an outer ring, a single row of balls, a cage and two metal shields.

The deep groove raceways allow the bearing to support radial loads and specified axial loads in both directions.

The metal shields form a non-contact clearance near the inner ring. They help restrict the entry of larger contaminants and retain lubricant inside the bearing.

However, they do not provide complete protection against water, fine dust or pressurized liquids.

Inner Ring

The inner ring has a nominal bore diameter of 12 mm and is mounted on the shaft using an appropriate fit.

Outer Ring

The outer ring has a nominal outside diameter of 32 mm and is installed in a suitable bearing housing.

Rolling Elements

The single row of balls transmits loads between the inner and outer raceways.

The deep groove geometry allows combined radial and axial loading within the bearing's operating limits.

Bearing Cage

The cage separates and guides the rolling elements, maintaining their distribution around the bearing circumference.

The exact cage material and design should be confirmed for the supplied FAG bearing version.

Double Metal Shields

The two metal shields provide non-contact protection on both sides of the bearing.

Their main functions are to help retain grease and reduce the entry of larger contaminants.

They are not equivalent to rubber contact seals.

FAG 6201 ZZ vs Other Bearing Variants

These comparisons describe bearing configurations, not confirmed interchangeable part numbers for every FAG execution.

Bearings with identical nominal dimensions of 12x32x10 mm may differ in shielding, internal clearance, lubrication and operating characteristics.

FAG 6201 ZZ vs FAG 6201

The basic 6201 bearing has an open construction.

The 6201 ZZ version incorporates two metal shields, providing additional protection against larger contaminants and helping retain lubricant.

FAG 6201 ZZ vs FAG 6201-2RSR

The 6201 ZZ uses non-contact metal shields.

The 6201-2RSR uses contact seals, which generally provide better protection against contamination but introduce additional friction.

The correct configuration depends on operating speed, environmental conditions and lubrication requirements.

FAG 6201 ZZ vs FAG 6201-C3

ZZ identifies the shield configuration, while C3 identifies increased radial internal clearance.

These design features are independent.

A double-shielded bearing can also be manufactured with increased internal clearance, provided that the corresponding version is offered by the manufacturer.

The correct clearance class must be selected according to mounting fits, temperature and operating requirements.

Alternative Designations and Search References

The FAG 6201 ZZ bearing may be identified using the following natural designation variants:

• 6201 ZZ FAG

• FAG 6201 ZZ

• 6201ZZ FAG

• FAG 6201ZZ

• 6201 2Z FAG

• FAG 6201-2Z

• FAG 6201 ZZ 12x32x10

• 6201 double shielded ball bearing

• FAG 6201 metal shielded bearing

• 6201 12x32x10 mm bearing

The FAG 6201-2Z designation identifies a bearing configuration with two metal shields.

However, complete equivalence with a product sold as 6201 ZZ should be verified against the manufacturer's exact marking and product documentation.

No unverified OEM numbers or manufacturer cross-references have been assigned.

Bearing Selection and Interchangeability

Before ordering FAG 6201 ZZ, verify the following requirements:

1. Complete manufacturer designation: confirm the exact FAG marking.

2. Bore diameter: 12 mm.

3. Outside diameter: 32 mm.

4. Bearing width: 10 mm.

5. Shield configuration: two non-contact metal shields.

6. Radial internal clearance: appropriate for the application.

7. Operating speed: compatible with the bearing design and lubrication.

8. Radial and axial loads: within the manufacturer's permissible limits.

9. Operating temperature: suitable for the bearing and lubricant.

10. Lubrication: compatible with the machine's operating conditions.

11. Shaft and housing fits: appropriate for the load and mounting arrangement.

12. Environmental conditions: suitable for the protection offered by metal shields.

Identical bearing dimensions do not automatically guarantee complete interchangeability.

In particular, a metal-shielded bearing may not be suitable as a direct replacement for a contact-sealed bearing.

Typical Applications of Double Shielded Deep Groove Ball Bearings

Double-shielded deep groove ball bearings are used in rotating assemblies where limited contamination protection and lubricant retention are required.

Typical applications for this bearing design include:

• Electric motors.

• Fans and blowers.

• Industrial drive mechanisms.

• Conveyor rollers.

• Small mechanical transmissions.

• General industrial machinery.

• Rotating equipment and auxiliary mechanisms.

These are typical applications based on the bearing's construction, not confirmed OEM applications for a specific equipment model.

The suitability of FAG 6201 ZZ must be determined from the actual operating conditions, including loads, rotational speed, lubrication and environmental exposure.

Installation, Lubrication and Storage

Installation Preparation

Before mounting, inspect the shaft, housing and bearing seating surfaces.

Remove dirt, metal particles and burrs that could interfere with proper installation.

Correct Mounting Force

When installing a bearing with an interference fit, apply mounting force directly to the ring being fitted.

Do not transmit installation force through the balls.

Avoid pressing against the metal shields, as they may become deformed or damaged.

Bearing Fits

Select the shaft and housing fits according to the direction of load, rotational conditions and operating temperature.

Incorrect fits can affect internal clearance and bearing performance.

Lubrication

Double-shielded deep groove ball bearings are commonly supplied with grease.

However, the exact lubricant type, quantity and delivery condition should be verified for the specific FAG execution.

The presence of metal shields does not automatically guarantee lifetime lubrication under every operating condition.

Shield Protection

Do not remove or deform the shields without a justified technical reason.

Damaged shields may reduce contamination protection or interfere with bearing operation.

Storage

Store the bearing in a clean, dry environment, preferably in its original packaging until installation.

Avoid unnecessary handling and exposure to moisture.

Frequently Asked Questions - FAG 6201 ZZ
