6700 H 2RS EZO 10x15x4 mm - Stainless Steel Deep Groove Ball Bearing

Product Description

6700 H 2RS EZO 10x15x4 mm is a miniature, single-row deep groove ball bearing manufactured under the Japanese EZO brand by Sapporo Precision Inc. It features a 10 mm bore diameter, 15 mm outside diameter and 4 mm width. The bearing belongs to the thin-section 6700 dimensional series, designed for compact rotating mechanisms where installation space is limited.

Its deep groove ball bearing construction supports primarily radial loads and can also accommodate axial loads in both directions, within the limitations of the bearing design.

The H designation identifies the stainless steel version, while 2RS indicates contact seals on both sides. This combination provides improved corrosion resistance compared with conventional bearing steel and additional protection against contamination.

The compact dimensions make EZO 6700H 2RS suitable for precision mechanical assemblies requiring a small bearing cross-section.

Technical Specifications - EZO 6700 H 2RS

The listed performance values correspond to the specified bearing configuration. Actual operating limits depend on the applied loads, lubrication, temperature, fits and mounting conditions.

What Does 6700 H 2RS EZO Mean?

6700 - Thin-Section Bearing Series

The designation 6700 identifies a miniature deep groove ball bearing with a nominal bore diameter of 10 mm and an outside diameter of 15 mm.

The 2RS version has a width of 4 mm.

This dimensional series is characterized by a particularly small radial cross-section.

H - Stainless Steel Construction

In this EZO bearing designation, the letter H identifies the stainless steel version.

Stainless steel offers increased resistance to corrosion compared with conventional bearing steel.

However, stainless steel does not provide unlimited protection against aggressive chemicals, prolonged water exposure or unsuitable environmental conditions.

2RS - Double Contact Seals

The suffix 2RS indicates two contact seals, one on each side of the bearing.

The seals help retain lubricant inside the bearing and reduce the ingress of dust, dirt and other contaminants.

EZO - Manufacturer Brand

EZO is a Japanese bearing brand associated with Sapporo Precision Inc., specializing in miniature and small-diameter ball bearings.

Construction and Operating Principle

The EZO 6700H 2RS consists of an inner ring, outer ring, rolling balls, cage and two contact seals.

Thin-Section Geometry

The bearing has an outside diameter of only 15 mm and a bore diameter of 10 mm.

The nominal radial cross-section is therefore:

This compact geometry allows the bearing to be installed in assemblies with very limited radial space.

However, thin-section bearings require careful selection of shaft and housing fits to avoid excessive deformation or changes in internal clearance.

Stainless Steel Rings and Balls

The stainless steel construction is advantageous in applications where improved corrosion resistance is required.

The material helps protect the bearing against certain environmental conditions that may accelerate corrosion in conventional bearing steel.

Nevertheless, the bearing should not automatically be considered suitable for continuous immersion, aggressive cleaning agents or corrosive chemical environments.

Double Contact Sealing

The two contact seals provide additional protection against contamination.

Compared with metal-shielded ZZ versions, contact seals generally offer a stronger barrier against dirt and moisture.

However, contact seals normally generate more friction than non-contact metal shields.

Ball and Cage Arrangement

The single-row ball arrangement supports smooth rotational movement.

The cage separates and guides the rolling elements, helping maintain their correct spacing during operation.

Radial and Axial Load Capacity

Radial Loads

The primary function of the EZO 6700H 2RS is to accommodate radial loads acting perpendicular to the shaft axis.

Its catalogue basic dynamic load rating is 729 N.

The basic static load rating is 348 N.

These ratings are reference parameters for bearing selection and do not represent universally permissible operating loads.

Axial Loads

Deep groove ball bearings can also accommodate axial loads in both directions.

However, the permissible axial load depends on the radial loading, bearing geometry, operating speed and other application conditions.

Operating Speed

The stated catalogue speed values are:

• Grease lubrication: 8,300 rpm.

• Oil lubrication: 9,400 rpm.

These values should not be interpreted as guaranteed permissible speeds under every operating condition.

Contact seal friction, lubrication, load and temperature must also be considered.

EZO 6700H 2RS vs 6700HZZ

6700H 2RS - Contact-Sealed Version

This version features two contact seals designed to limit contamination and retain lubricant.

It may be preferred where protection against dust and dirt is important.

6700HZZ - Metal-Shielded Version

The ZZ version features metal shields on both sides.

Metal shields generally create less friction than contact seals but offer different protection characteristics.

6700H 2RS and 6700HZZ are not identical bearing configurations, even though their principal mounting dimensions are the same.

EZO 6700H 2RS vs Standard 6700 2RS

The main difference concerns the material specification.

6700H 2RS identifies the stainless steel version with contact seals on both sides.

6700 2RS refers to a standard material version with double contact sealing.

When selecting a replacement, the bearing dimensions alone are not sufficient.

Corrosion resistance, load ratings, speed limits and environmental conditions should also be evaluated.

Installation, Lubrication and Maintenance

Preparation Before Installation

Inspect the shaft and housing bore for dimensional accuracy, surface damage and contamination.

The mating surfaces should be clean and free from burrs.

Correct Mounting

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

Do not transmit installation forces through the rolling balls.

Because the bearing has a thin radial cross-section, excessive mounting pressure or incorrect fits may cause deformation and affect bearing performance.

Lubrication

Double-sealed miniature bearings are commonly supplied with lubricant inside the bearing.

However, the exact lubricant type, fill quantity and service temperature range should be confirmed for the specific EZO execution.

Do not remove the seals or add lubricant without following the manufacturer's recommendations.

Contamination Protection

The 2RS seals help protect the bearing interior against contaminants.

They do not make the bearing universally waterproof or suitable for all aggressive environments.

Operating Inspection

During operation, monitor the bearing assembly for unusual noise, vibration, temperature increase or excessive resistance to rotation.

These symptoms may indicate unsuitable loading, mounting errors, contamination or bearing wear.

Storage

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

Protect the seals and precision bearing surfaces from damage.
