PTI 6000-ZZ 10x26x8 Deep Groove Ball Bearing

PTI 6000-ZZ 10x26x8 Deep Groove Ball Bearing

PTI 6000-ZZ is a single-row deep groove ball bearing with dimensions of 10x26x8 mm. It belongs to the 6000 dimensional series and is equipped with two metal shields, identified by PTI with the ZZ suffix. The shields help protect the bearing interior from contamination and retain lubricant while avoiding the construction of contact elastomer seals.

PTI 6000-ZZ - Technical Characteristics

Manufacturer: PTI

Designation: 6000-ZZ

Bearing type: Single-row deep groove ball bearing

Series: 6000

Dimensions: 10x26x8 mm

Closure: ZZ - two metal shields

The complete 6000-ZZ designation is important because it distinguishes this version from open and elastomer-sealed 6000 bearings.

PTI 6000-ZZ Dimensions

The principal dimensions are:

d = 10 mm - bore diameter

D = 26 mm - outside diameter

B = 8 mm - bearing width

Complete size:

10x26x8 mm

These dimensions identify the basic 6000 bearing size, while the ZZ suffix defines the shield configuration.

What Does ZZ Mean?

In the PTI catalogue, 6000-ZZ is listed as a bearing with:

2 Shields

This means that the bearing has a metal shield on each side.

The ZZ design should be distinguished from:

6000-2RS - two seals

Metal shields and elastomer seals are different closure systems and can provide different operating characteristics.

Deep Groove Ball Bearing Construction

PTI 6000-ZZ is a single-row deep groove ball bearing.

Its construction consists of an inner ring, outer ring, one row of balls and a cage.

The deep raceway geometry is primarily designed to accommodate radial loads while also allowing axial loads in both directions within the operating limits of the bearing and its mounting arrangement.

Dynamic Load Rating

For the exact PTI 6000-ZZ, the manufacturer catalogue specifies:

Dynamic load rating C = 790 lbf

This corresponds to approximately:

C = 3.51 kN

The dynamic load rating is a catalogue parameter used in bearing life calculations under dynamic loading conditions.

Values from other 6000-ZZ manufacturers should not automatically be transferred to the PTI product.

Static Load Rating

PTI specifies:

Static load rating C0 = 432 lbf

Equivalent to approximately:

C0 = 1.92 kN

The static load rating is relevant when evaluating a bearing under stationary or slowly varying loading conditions.

Maximum Speed

The PTI catalogue specifies:

Maximum speed = 31,000 rpm

This is the manufacturer's catalogue value for the exact 6000-ZZ version.

Actual permissible operating speed in a machine also depends on factors including lubrication, load, fit, operating temperature and heat dissipation.

Bearing Weight

Catalogue weight:

0.042 lb

Equivalent to approximately:

0.019 kg

Weight values for nominally similar 6000-ZZ bearings from other manufacturers may differ slightly depending on their exact internal construction.

6000-ZZ vs 6000-2RS

PTI lists the 6000 bearing size in different closure configurations.

6000-ZZ - two metal shields

6000-2RS - two seals

Both versions share the principal 10x26x8 mm dimensions, but the closure design is different.

This distinction should be considered when selecting a replacement.

Metal Shields vs Contact Seals

A metal shield does not function in exactly the same way as a contact elastomer seal.

The ZZ design provides physical protection around the bearing interior without using a conventional contacting rubber sealing lip.

This construction is particularly relevant where low friction and rotational speed are important design considerations.

The required protection level should always be matched to the actual operating environment.

Load Direction

A deep groove ball bearing is designed primarily for:

radial loads

Its raceway geometry also allows it to accommodate:

axial loads in both directions

The permissible combination of radial and axial loading depends on the complete operating conditions.

Replacement Selection

When selecting a replacement for PTI 6000-ZZ, verify:

d = 10 mm

D = 26 mm

B = 8 mm

single-row deep groove ball bearing design

two metal shields

required radial internal clearance

required tolerance class

load ratings

speed requirements

operating environment

Matching only the 10x26x8 mm dimensions does not define every technical characteristic of the bearing.

FAQ

What are the dimensions of PTI 6000-ZZ?

The bearing measures 10x26x8 mm: 10 mm bore diameter, 26 mm outside diameter and 8 mm width.

What type of bearing is PTI 6000-ZZ?

It is a single-row deep groove ball bearing.

What does ZZ mean on PTI 6000-ZZ?

ZZ identifies two metal shields, with one shield on each side of the bearing.

Is PTI 6000-ZZ sealed on both sides?

It is shielded on both sides with metal shields. This should be distinguished from an elastomer-sealed 2RS bearing.

What is the dynamic load rating of PTI 6000-ZZ?

PTI specifies 790 lbf, equivalent to approximately 3.51 kN.

What is the static load rating?

The PTI catalogue specifies 432 lbf, approximately 1.92 kN.

What is the maximum speed of PTI 6000-ZZ?

The manufacturer's catalogue value is 31,000 rpm.

What is the weight of PTI 6000-ZZ?

The catalogue weight is 0.042 lb, approximately 0.019 kg.

Engineer FAQ

Is ZZ the same as 2RS?

No. ZZ identifies two metal shields, while 2RS identifies two elastomer seals in PTI nomenclature.

Are ZZ and 2Z similar designations?

Both designations are commonly associated with bearings shielded on both sides, but for this exact PTI product the manufacturer's designation should be retained as 6000-ZZ.

Can PTI 6000-ZZ accommodate axial loads?

Yes. Deep groove ball bearing geometry allows axial loads to be accommodated in both directions, subject to the limits of the bearing and operating conditions.

Can any 6000-ZZ replace PTI 6000-ZZ?

Nominal dimensions may be identical, but load ratings, internal design, clearance, cage configuration and other parameters can vary between manufacturers. The complete specification should be checked.

Can 6000-ZZ be replaced with 6000-2RS?

This should not be assumed automatically. Although both may have dimensions of 10x26x8 mm, the metal-shield and elastomer-seal designs have different operating characteristics.

Why should PTI load ratings be used instead of values from another manufacturer?

Because load ratings can depend on the manufacturer's internal bearing design. For this product, calculations and technical descriptions should use the values specified for the exact PTI 6000-ZZ.
