35x72x23 mm
NJ 2207 ZVL single-row cylindrical roller bearing with high radial load capacity. The NJ design locates the shaft axially in one direction and allows relative axial displacement of the rings in the opposite direction.
40x90x23 mm
Rolling bearing 6308 ZKL for use in machinery and equipment.
30x62x23 mm
3206 ZKL double-row angular contact ball bearing for combined radial and axial loads in both directions. Its compact design provides rigid and accurate shaft guidance.
65x120x23 mm
ZKL 6213 bearing with clearly stated mounting dimensions. The product name gives no suffix for closure or clearance; compare the complete marking on the original bearing before replacement.
35x72x23 mm
ZKL NU 2207 single-row cylindrical roller bearing for high radial loads. The NU design has two integral flanges on the outer ring and permits axial displacement of the shaft relative to the housing in both directions, making it suitable for a non-locating bearing position.
40x80x23 mm
NU 2208 E ZVL is a single-row cylindrical roller bearing for high radial loads. The NU design permits axial displacement of the shaft relative to the housing in both directions and is suited to non-locating positions.
40x90x23 mm
6308 FAG deep-groove ball bearing is a single-row radial bearing in the robust 63 dimension series for a 40 mm shaft. Deep raceways support radial loads and moderate axial forces in both directions with smooth running and low friction. The open design suits clean, correctly lubricated assemblies or machines that provide separate external protection.
55x90x23 mm
The 32011 FBJ single-row tapered roller bearing is a separable bearing for combined radial and axial loads. Tapered raceways and rollers provide high rigidity and load-carrying capacity.
One bearing supports axial load in one direction; an opposed pair is used for axial location in both directions. The open design requires suitable lubrication.
6213 C3 ZVL deep-groove ball bearing is an open single-row bearing with greater-than-normal C3 radial internal clearance. It carries radial loads and moderate axial loads in both directions and suits arrangements where interference fits or operating temperatures reduce internal clearance.
6213 2RSR ZVL deep-groove ball bearing is a single-row bearing with contact rubber seals on both sides. It carries radial loads and moderate axial loads in both directions, while the factory grease is protected against leakage and common contaminants.
Cylindrical roller bearing NU 2210 ZKL is a single-row radial bearing with high load capacity. The NU design has two integral flanges on the outer ring and an inner ring without flanges.
It permits axial displacement of the shaft relative to the housing in both directions and is therefore primarily used as a non-locating bearing. It does not provide axial shaft location.
40x90x23 mm
Metal shields on both sides
Greater radial internal clearance
Single-row deep-groove ball bearing 6308 2Z C3 SKF for radial load and axial loads in both directions. Two non-contact metal shields retain lubricant with low friction; C3 clearance provides allowance for tight fits or elevated operating temperature.
35x72x23 mm
Double-row self-aligning ball bearing 2207 ZKL with a cylindrical bore. The spherical outer-ring raceway accommodates angular misalignment; suitable primarily for radial load and limited axial load in both directions.
45x85x23 mm
Double-row self-aligning ball bearing 2209 E2RS1TN9 SKF with contact seals on both sides and a polyamide cage. It accommodates slight misalignment and shaft deflection and carries radial loads together with light axial loads in both directions.
35x72x23 mm
NJ 2207 ZKL single-row cylindrical roller bearing is designed for high radial loads and can also locate the shaft axially in one direction. Its separable construction allows the inner ring to be installed independently of the outer ring and roller assembly.
40x80x23 mm
Single-row cylindrical roller bearing NU 2208 E DPI for high radial loads. The NU design allows axial displacement of the shaft relative to the housing in both directions; E denotes an increased-capacity internal design.
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.
