F-686HZZ EZO 6x13x5 mm - Stainless Steel Flanged Deep Groove Ball Bearing

F-686HZZ EZO 6x13x5 mm - Stainless Steel Flanged Deep Groove Ball Bearing

EZO F-686HZZ is a miniature stainless steel flanged deep groove ball bearing with basic dimensions 6x13x5 mm, fitted with metal shields on both sides. The F designation identifies the flanged design, H identifies the stainless steel EZO version, and ZZ indicates metal shields on both sides. The flange on the outer ring facilitates axial positioning of the bearing in the housing.

Technical data

EZO F-686HZZ dimensions

The basic bearing dimensions are:

d: 6 mm
D: 13 mm
B: 5 mm

Basic dimensional specification:

6x13x5 mm

Because F-686HZZ is a flanged bearing, the dimensions and geometry of the outer-ring flange must also be considered when selecting the bearing for a specific housing.

What does F-686HZZ mean?

The complete F-686HZZ designation describes the bearing design and should be retained when identifying or ordering the product.

F - flanged outer ring.

686 - miniature deep groove ball bearing size with basic dimensions 6x13x5 mm.

H - stainless steel version in this EZO bearing series.

ZZ - metal shields on both sides.

Each element of the designation is relevant to correct bearing identification.

Flanged design

The principal difference between F-686HZZ and a standard 686HZZ is the flange on the outer ring.

The flange can:

• facilitate axial positioning of the bearing,
• provide a locating surface during assembly,
• help prevent axial displacement in a suitably designed housing,
• simplify the design of compact bearing arrangements.

This is particularly useful in miniature mechanisms where there is limited space for additional locating components.

EZO F-686HZZ construction

The bearing consists of:

• inner ring,
• flanged outer ring,
• balls,
• cage,
• two metal shields.

As a deep groove ball bearing, it is designed primarily to accommodate radial loads. It can also accommodate axial loads within the operating limits of the specific bearing arrangement.

Stainless steel H version

The H designation identifies the stainless steel EZO version.

Compared with conventional bearing steel, stainless steel provides improved corrosion resistance, which can be advantageous in environments exposed to moisture.

Suitability for aggressive chemicals or specific corrosive environments should always be evaluated according to the actual operating conditions.

What does ZZ mean?

ZZ indicates metal shields on both sides of the bearing.

The shields help to:

• reduce the ingress of contaminants,
• protect the raceways and rolling elements,
• retain lubricant inside the bearing,
• maintain low running friction.

ZZ metal shields should not be confused with elastomer seals such as 2RS.

F-686HZZ vs 686HZZ

Both bearings have the same basic dimensions:

6x13x5 mm

The key difference is the outer-ring design.

F-686HZZ - stainless steel version with an outer-ring flange and ZZ shields.

686HZZ - stainless steel version without the flange, with ZZ shields.

They should therefore not automatically be considered interchangeable. The flange affects bearing location and the geometry required in the housing.

F-686HZZ vs F-686ZZ

The H designation is also important when comparing material versions.

F-686HZZ - stainless steel version.

F-686ZZ - standard material version.

If stainless steel construction is required, the complete F-686HZZ designation should be retained.

Selection and interchangeability

When selecting EZO F-686HZZ, verify:

• complete F-686HZZ designation,
• 6 mm bore diameter,
• 13 mm basic outside diameter,
• 5 mm width,
• flange geometry and diameter,
• stainless steel H version,
• ZZ metal shields,
• required load capacity,
• operating speed,
• environmental conditions,
• shaft and housing tolerances.

Matching the basic 6x13x5 mm dimensions alone does not confirm interchangeability for a flanged bearing.

Applications

Miniature flanged bearings are suitable for compact precision mechanisms where accurate axial positioning of the bearing is required within limited installation space.

The stainless steel F-686HZZ version can additionally be useful where improved corrosion resistance is required.

Suitability for a specific application should always be determined according to actual loads, operating speed, environmental conditions and the complete bearing arrangement.

Installation

The flange should locate against a suitably designed shoulder or locating surface in the housing.

During installation:

• apply mounting force to the inner ring when fitting onto a shaft,
• apply mounting force to the outer ring when pressing into a housing,
• do not transmit mounting force through the balls,
• avoid direct pressure on the ZZ metal shields.

Excessive mounting force should be avoided because of the bearing's miniature dimensions.

FAQ - EZO F-686HZZ

What are the dimensions of EZO F-686HZZ?

The basic bearing dimensions are 6x13x5 mm, with a 6 mm bore, 13 mm basic outside diameter and 5 mm width. The F version additionally has a flange on the outer ring.

What does F mean in F-686HZZ?

F identifies the flanged version. The flange is located on the outer ring and facilitates axial positioning in the housing.

Is EZO F-686HZZ made of stainless steel?

Yes. The H designation identifies the stainless steel version in this EZO bearing series.

What does ZZ mean?

ZZ indicates metal shields on both sides of the bearing.

What is the difference between F-686HZZ and 686HZZ?

F-686HZZ has a flange on the outer ring. Standard 686HZZ does not have this flange.

Are F-686HZZ and 686HZZ directly interchangeable?

Not automatically. Although their basic bearing dimensions are 6x13x5 mm, the flange and housing geometry must also be considered.

Can any flanged 6x13x5 mm bearing replace F-686HZZ?

Not automatically. Flange geometry, material version, closure type and required operating characteristics must also be verified.
