609 ZZ ABEG 9x24x7 mm is a single-row deep groove ball bearing with metal shields on both sides. The bearing has a 9 mm bore diameter, 24 mm outside diameter and 7 mm width. The ZZ designation indicates two metal shields designed to help protect the rolling elements from dust and contamination while retaining lubricant inside the bearing.
The deep groove raceway design makes the 609 ZZ suitable primarily for radial loads, while also allowing appropriate axial loads in both directions.

When selecting a replacement bearing, dimensions should be checked together with the closure type, internal clearance and operating requirements.
What Does 609 Mean?
The designation 609 identifies a deep groove ball bearing with standard principal dimensions of:
9x24x7 mm
Deep groove ball bearings are among the most widely used rolling bearing designs because of their simple construction, relatively low friction and ability to accommodate both radial and appropriate axial loading.
The compact dimensions of the 609 series make it particularly relevant to smaller mechanical assemblies.
What Does ZZ Mean on a 609 Bearing?
The designation ZZ indicates that the bearing is fitted with metal shields on both sides.
Depending on manufacturer terminology, similar configurations may be identified as:
609 ZZ
609ZZ
609 2Z
609-2Z
Metal shields help:
- limit the ingress of dust and contaminants
- protect the rolling elements and raceways
- retain lubricant inside the bearing
- maintain relatively low running friction
Shielded bearings are particularly useful where protection is required without the additional friction associated with contact seals.
Deep Groove Ball Bearing Design
The 609 ZZ ABEG is a single-row deep groove ball bearing.
Its raceway geometry allows it to accommodate primarily radial loads while also supporting appropriate axial loads in both directions.
Important characteristics of deep groove ball bearings include:
- simple and compact construction
- relatively low friction
- suitability for high rotational speeds
- radial load capability
- axial load capability in both directions
- broad range of mechanical applications
Metal Shields on Both Sides
The metal shields are positioned on both sides of the bearing.
Unlike typical contact rubber seals, metal shields normally operate without direct contact with the inner ring. This helps reduce friction and makes shielded bearings suitable for applications where rotational speed and low resistance are important.
The trade-off is that a shielded bearing generally provides less protection against moisture and severe contamination than a bearing equipped with contact seals.
609 ZZ vs 609 2RS
Both versions normally share the same principal dimensions:
9x24x7 mm
The main difference is the closure design.
609 ZZ - metal shields on both sides, providing contamination protection with relatively low friction.
609 2RS - elastomer seals on both sides, providing more extensive protection against contamination and moisture.
The correct version should be selected according to the operating environment, rotational speed and required level of protection.
Radial and Axial Load Capability
Deep groove ball bearings are primarily designed to carry radial loads.
Due to the geometry of the raceways, the 609 ZZ can also accommodate appropriate axial loading in both directions.
Actual permissible loads depend on the bearing specification and operating conditions. The bearing should therefore be selected according to the requirements of the specific machine rather than dimensions alone.
Applications of the 609 ZZ ABEG Bearing
The compact 609 ZZ 9x24x7 mm bearing can be used in appropriately designed:
- electric motors
- small drive systems
- power tools
- fans
- workshop equipment
- precision mechanisms
- industrial machinery
- mechanical equipment
- compact rotating assemblies
The exact suitability should always be verified for the specific application.
How to Select a 609 ZZ Bearing
When replacing a bearing, check:
Designation: 609 ZZ
Dimensions: 9x24x7 mm
Bore Diameter: 9 mm
Outside Diameter: 24 mm
Width: 7 mm
Closure: metal shields on both sides
Internal Clearance: according to application requirements
Speed: suitable for the operating conditions
Loads: radial and axial forces acting on the bearing
Two bearings with identical 9x24x7 mm dimensions are not necessarily fully interchangeable if their internal clearance, closure design or other technical characteristics differ.
