6001 ZZ CT 12x28x8 mm Deep Groove Ball Bearing

6001 ZZ CT is a single-row deep groove ball bearing measuring 12x28x8 mm, fitted with metal shields on both sides. The ZZ designation identifies the double-shielded configuration. Its nominal dimensions are d = 12 mm, D = 28 mm and B = 8 mm. The deep raceway geometry enables this bearing type to accommodate radial loads as well as axial loads in both directions. Manufacturer-specific CT load ratings, speed limits and internal clearance are not stated without confirmed CT catalogue data.

6001 ZZ CT Dimensions

The basic dimensions are:

d - Bore Diameter: 12 mm
D - Outside Diameter: 28 mm
B - Width: 8 mm

Complete size: 12x28x8 mm

These are the standard boundary dimensions associated with the 6001 bearing designation.

ZZ Double-Shielded Design

The suffix ZZ indicates that the bearing is equipped with:

two metal shields - one on each side of the bearing.

The shields help reduce the entry of larger contaminants and help retain lubricant inside the bearing.

A metal shield is not the same construction as a contacting elastomer seal. Therefore, 6001 ZZ should not be confused with 6001 2RS.

Deep Groove Ball Bearing Construction

6001 belongs to the single-row deep groove ball bearing family.

Deep raceway grooves provide close conformity between the balls and raceways. This geometry enables the bearing to accommodate primarily radial loads, while also supporting axial loads in both directions.

The bearing is a non-separable design.

6001 ZZ vs 6001 2RS

Both versions commonly have the same basic dimensions:

12x28x8 mm

The principal difference is the closure system:

6001 ZZ - metal shields on both sides
6001 2RS - elastomer seals on both sides

These closure types have different friction and sealing characteristics, so they should not automatically be treated as technically identical.

6001 ZZ vs 6001-2Z

The designation used for double metal shields varies between manufacturers.

ZZ is a widely used designation for metal shields on both sides.

Some manufacturers use 2Z for the same general closure concept. For example, SKF uses the designation 6001-2Z for its double-shielded version.

This does not mean that 6001 ZZ bearings from different manufacturers have identical load ratings, internal clearance, speed limits, cage specifications or lubricant.

Load Capability

As a deep groove ball bearing, the 6001 design is suitable for accommodating:

radial loads

and

axial loads in both directions.

Specific dynamic and static load ratings are not assigned to this CT bearing without confirmed manufacturer data.

Load ratings published for SKF, FAG, NSK, NTN or other manufacturers should not automatically be copied to 6001 ZZ CT.

Selection and Interchangeability

When selecting a replacement for 6001 ZZ CT, verify:

• designation 6001
• dimensions 12x28x8 mm
• double metal shields ZZ
• required radial internal clearance
• accuracy class
• load ratings
• permissible speed
• lubrication requirements

Matching the 12x28x8 mm dimensions alone does not establish complete technical interchangeability.

FAQ

What are the dimensions of 6001 ZZ CT?

The bearing measures 12x28x8 mm, with a 12 mm bore, 28 mm outside diameter and 8 mm width.

What type of bearing is 6001 ZZ CT?

It is a single-row deep groove ball bearing.

What does ZZ mean on a 6001 bearing?

ZZ indicates metal shields on both sides of the bearing.

Is 6001 ZZ the same as 6001 2RS?

No. 6001 ZZ uses metal shields, while 6001 2RS uses elastomer seals on both sides.

Is 6001 ZZ similar to 6001-2Z?

ZZ and 2Z are commonly used by different manufacturers to identify the general configuration of metal shields on both sides. Manufacturer-specific specifications can still differ.

Can 6001 ZZ accommodate axial loads?

Yes. Deep groove ball bearings can accommodate radial loads and axial loads acting in both directions.

Is every 6001 ZZ bearing technically identical?

No. Bearings can differ in internal clearance, accuracy class, cage, lubricant, load ratings and permissible speeds depending on manufacturer and execution.

Can any 12x28x8 mm bearing replace 6001 ZZ CT?

Not automatically. The bearing type, dimensions, closure system, internal clearance and operating requirements should all be verified.
