9x24x7 mm
Single-row 609 2Z NMB deep-groove ball bearing
Metal shields on both sides; compare the complete designation, including suffixes.
9x24x7 mm
609 2Z ZKL single-row deep groove ball bearing with non-contact metal shields on both sides. Suitable for radial and moderate axial loads in both directions, combining low friction with protection of the lubricant from larger contaminants.
9x24x7 mm
609 Z ZKL single-row deep groove ball bearing with a non-contact metal shield on one side. Suitable for radial and moderate axial loads in both directions when one side of the bearing needs protection from coarse contamination.
8x24x8 mm
Open single-row 628 deep-groove ball bearing for accurate support of small shafts and rotating mechanisms. It carries radial load and limited axial load in both directions.
9x24x7 mm
Compact ZKL single-row deep groove ball bearing for precise rotating assemblies.
8x24x8 mm
ZKL 628 2Z single-row deep-groove ball bearing with non-contact metal shields on both sides for low friction and protection from ordinary contamination.
15x24x5 mm
6802 2RS EZO thin-section ball bearing is an exceptionally compact single-row bearing for a 15 mm shaft. Rubber 2RS seals on both sides protect the rolling contact and retain lubricant. Its low cross-section and 5 mm width suit precision mechanisms with limited space and moderate loading.
10x24x9 mm
STEYR 51100 thrust ball bearing is designed to carry axial load in one direction. It is used where force acting along the shaft axis must be reliably supported.
10x24x9 mm
ZVL 51100 thrust ball bearing is designed to carry axial load in one direction. It is used where force acting along the shaft axis must be reliably supported.
Rubber seals on both sides
18x24x16 mm
NTN needle roller bearing for compact radial arrangements. Verify designation, dimensions and application requirements in the manufacturer documentation.
18x24x12 mm
CRB needle roller bearing for compact radial arrangements. Before selection, verify the complete designation, dimensions and application requirements in the manufacturer documentation.
Metal shield on one side
Practical advice
How to choose the right bearing
The same dimensions do not necessarily mean the same function. When selecting a replacement, check the construction, cover and seal design, internal clearance, and the conditions in which the bearing will operate.
Determine the type and size
Copy the full type designation. If missing, measure the inner diameter d, outer diameter D and width B.
Check the design
Distinguish open bearing, metal shields, and rubber seals. Also check internal clearance, accuracy, cage, and lubricant.
Take operating conditions into account
Rotational speed, direction, and magnitude of mechanical load, temperature, humidity, dust, and the method of installation are decisive.
How to read the type designation 6204 2RS C3
Suffixes may vary between manufacturers. When replacing, compare technical parameters, not just similar type designation.
Open, 2Z, or 2RS?
When are matching dimensions not enough?
A dimensionally identical bearing may have different load capacity, maximum speed, precision, or internal clearance. Pay special attention to electric motors, high temperatures, vibrations, shocks, and dusty or humid environments.
- radial, axial, and combined loads
- normal or increased internal clearance C3/C4
- operating temperature and maximum speed
- design of shields and seals, lubricant, cage material, and precision
Frequently asked questions
Can I replace a bearing with another brand?
Usually yes, if the design type, dimensions, internal clearance, precision, cover and seal design, load capacity, and allowable speeds match. The basic number alone is not enough; the meaning of the suffixes may vary according to the manufacturer.
How do I determine the diameter of the inner bore from the model designation?
For many common metric bearings, the bore diameter code from 04 is multiplied by five: for example, 04 = 20 mm and 06 = 30 mm. Codes 00 to 03 and some special designs have different rules, so it is advisable to verify the dimension.
Is 2RS better, or 2Z?
Neither is universally better. 2RS usually protects better against dirt and moisture, while 2Z tends to have lower friction and allows higher speeds. The right choice depends on the application.
What to send if the type designation is unreadable?
A photo of both sides, dimensions d × D × B, machine type, and information about speed, load, temperature, humidity, or dustiness. The more operational data we know, the more safely a replacement can be recommended.
Not sure about the replacement?
Send the type designation, dimensions, or a photo of the original part. We will help verify the suitable version before ordering.
