607ZZ Bearing

ال 607ZZ deep groove ball bearing is a compact radial bearing developed for equipment requiring stable rotation, reliable load support and long operating life. Measuring only 7×19×6mm, the 607 series provides an effective balance between miniature dimensions and mechanical performance.

NKMB manufactures 607 series bearings for OEM equipment producers, motor manufacturers and industrial bearing distributors. Available configurations include 607 open bearings, 607-Z single shield bearings, 607-ZZ double shield bearings and 607-2RS rubber sealed bearings.

For applications with higher requirements for rotational accuracy and noise control, NKMB can also supply selected P5 precision and ZV3 low-vibration bearing solutions according to customer requirements.

One Bearing Size, Multiple Protection Options

Different operating environments require different bearing closures. ال 607 series allows engineers and purchasing teams to select the most suitable configuration without changing the basic installation dimensions.

607 Open – Suitable for applications where external lubrication is available or minimal rotational resistance is required.

607-Z – A single metal shield protects one side of the bearing while maintaining low friction.

607-ز. – Double metal shields help protect the internal rolling elements against dust and retain grease during operation.

607-2ريال سعودي – Rubber seals on both sides provide improved protection in environments exposed to moisture, dirt or fine particles.

NKMB can assist customers in selecting the correct closure based on speed, contamination level and operating conditions.

607 Series Bearing Specifications

*Bearing cross references should be confirmed according to the customer’s equipment, internal design and technical requirements before replacement.

Developed for Stable Load Support

Although the 607 bearing belongs to the miniature bearing range, its deep raceway geometry allows it to support radial loads and limited axial loads from both directions.

NKMB pays particular attention to raceway grinding accuracy and internal component consistency. Correct groove geometry helps distribute operating loads across the rolling elements, reducing localized stress during continuous rotation.

For miniature motors and precision mechanical assemblies, this can contribute to more stable operation and longer bearing service life.

P5 Precision for Demanding Equipment

Standard bearing accuracy is suitable for many general applications. لكن, precision instruments, high-quality motors and sensitive rotating assemblies may require tighter dimensional and rotational tolerances.

For these applications, NKMB can manufacture selected 607 bearings to P5 precision requirements.

Improved bearing accuracy can help achieve:

• More stable shaft rotation
• Reduced radial runout
• Better assembly consistency
• Improved rotational accuracy
• Reliable performance in precision equipment

NKMB recommends confirming speed, shaft tolerance and housing fit before selecting a higher precision grade.

ZV3 Low Noise and Vibration Control

Bearing noise is influenced by more than lubrication alone. Raceway surface quality, steel ball grade, cleanliness, internal clearance and assembly control all affect vibration performance.

For low-noise applications, NKMB applies controlled grinding, cleaning and assembly processes to selected ZV3 607 bearings.

The grease filling quantity can also be controlled according to the intended application. This is particularly important for miniature motors and precision instruments where excessive grease or contamination may affect rotational performance.

Where Are NKMB 607 Bearings Used?

NKMB 607 series bearings can be found in compact rotating systems such as miniature electric motors, precision instruments, office equipment, small power transmission units, automation devices, measuring equipment, household appliances and mechanical control systems.

ال 607ز. configuration is frequently selected for applications requiring low maintenance and reliable dust protection.

For harsher environments, the 607-2ريال سعودي version provides additional sealing protection.

From Steel Selection to Final Noise Inspection

A reliable miniature bearing requires control at every manufacturing stage.

At NKMB, 607 bearing production can include raw material inspection, ring turning, heat treatment, precision grinding, raceway superfinishing, component cleaning, automatic assembly, grease filling and final performance inspection.

Depending on the customer’s quality requirements, inspection items may include:

• Bore and outside diameter tolerance
• Bearing width
• Radial clearance
• Rotational accuracy
• Vibration level
• Abnormal noise inspection
• Appearance and shield inspection
• Grease filling consistency

This process helps NKMB maintain stable batch-to-batch quality for international OEM and distribution customers.

Need a Specific 607 Bearing Configuration?

A motor manufacturer may need a low-noise 607ZZ bearing. A precision equipment producer may require P5 accuracy. Another customer may prefer 607-2RS bearings for improved contamination protection.

NKMB supports different technical requirements instead of limiting customers to a single standard configuration.

Customers can request specific precision grades, vibration levels, radial clearance, grease types, laser markings and private packaging.
