607 ZZ SKF 7x19x6 - Shielded Deep Groove Ball Bearing

607 ZZ SKF 7x19x6 - Shielded Deep Groove Ball Bearing

607 ZZ SKF is a single-row deep groove ball bearing with dimensions 7x19x6 mm, designed primarily for radial loads while also accommodating moderate axial loads in both directions. The ZZ configuration indicates metal shields on both sides of the bearing, helping retain lubricant and protect the rolling elements against larger contaminants. Its compact dimensions make the 607 series suitable for small electric motors, power tools, automation equipment and precision rotating mechanisms.

The 607 designation identifies the bearing dimensional series. When selecting a replacement, the dimensions should be checked together with the closure type, internal clearance and any additional suffixes.

What Does ZZ Mean on a 607 Bearing?

The designation ZZ is commonly used for a bearing equipped with metal shields on both sides.

The shields help reduce the ingress of larger contaminants while retaining grease within the bearing.

Unlike typical contacting rubber seals, metal shields operate with very low friction. This makes shielded bearings useful in applications where rotational speed and low running resistance are important.

Deep Groove Ball Bearing Design

The SKF 607 uses a single row of balls running in deep raceway grooves in the inner and outer rings.

This geometry enables the bearing to accommodate:

• radial loads
• moderate axial loads
• axial loads in both directions
• combined radial and axial loads

Deep groove ball bearings are characterized by relatively low friction and are suitable for high rotational speeds when correctly selected and installed.

607 ZZ vs 607 2RS

Both versions have the basic 7x19x6 mm dimensions, but they differ in their closure system.

607 ZZ: metal shields on both sides
607 2RS: elastomer seals on both sides

The ZZ version generally provides lower friction and good speed capability, while a sealed version typically offers greater protection in environments exposed to dust, moisture or contamination.

The two versions should not automatically be considered interchangeable without checking the operating conditions.

Applications of SKF 607 ZZ

Due to its compact dimensions, the 607 bearing can be used in appropriately designed:

• small electric motors
• power tools
• workshop equipment
• drive mechanisms
• rollers and guides
• automation equipment
• small fans
• compact pumps
• technical devices
• precision rotating mechanisms

Final bearing selection should consider load, rotational speed, temperature, required internal clearance and environmental conditions.

Low-Friction Shielded Construction

One of the main advantages of a shielded bearing is the combination of internal protection and relatively low running resistance.

The metal shields do not create the same level of contact friction as conventional contacting seals. This is particularly useful in compact mechanisms where rotational efficiency and speed capability are important.

At the same time, the shields help retain grease within the bearing throughout operation.

Radial and Axial Load Capability

Deep groove raceways allow the 607 ZZ bearing to support primarily radial forces.

The bearing can also accommodate axial forces acting in either direction, making the design suitable for compact mechanisms where radial and axial loads may occur simultaneously.

Actual permissible loads depend on operating speed, mounting conditions, lubrication and application requirements.

Replacement Selection for 607 ZZ

When selecting a replacement, verify:

Bearing designation: 607
Dimensions: 7x19x6 mm
Bore diameter: 7 mm
Outside diameter: 19 mm
Width: 6 mm
Closure: Metal shields on both sides
Manufacturer: SKF
Internal clearance: According to application requirements

A bearing with the same 7x19x6 mm dimensions may not necessarily be a direct replacement if it has different seals, internal clearance, lubrication or special execution.

Operational Advantages

Compact 7x19x6 mm dimensions: suitable for small mechanisms with limited installation space.

Double metal shielding: helps protect the rolling elements and retain lubricant.

Low running resistance: shielded construction is suitable for applications requiring limited friction.

Combined load capability: deep raceways allow radial and moderate axial loads.

Grease retention: shields help keep lubricant inside the bearing.

Versatile design: suitable for numerous compact industrial and mechanical applications.

FAQ - SKF 607 ZZ

What are the dimensions of SKF 607 ZZ?
The bearing measures 7x19x6 mm, with a 7 mm bore, 19 mm outside diameter and 6 mm width.

What type of bearing is SKF 607 ZZ?
It is a single-row deep groove ball bearing.

What does ZZ mean on a 607 bearing?
ZZ indicates that the bearing has metal shields on both sides.

Can SKF 607 ZZ accommodate axial loads?
Yes. In addition to radial loads, a deep groove ball bearing can accommodate moderate axial loads in both directions.

What is the difference between 607 ZZ and 607 2RS?
607 ZZ uses metal shields, while 607 2RS uses elastomer seals. The shielded version typically has lower friction, while sealed variants generally provide stronger protection against external contamination.

Does a 607 ZZ bearing require additional lubrication?
Double-shielded bearings are generally supplied with grease inside and are normally intended to operate without routine relubrication.

Where is a 607 ZZ bearing commonly used?
Typical applications include small electric motors, power tools, rollers, automation equipment and compact rotating mechanisms.

Can another 7x19x6 bearing replace SKF 607 ZZ?
Not automatically. Dimensions must match, but closure type, internal clearance, lubrication and operating requirements should also be verified.
