40x90x33 mm
2308 ZKL double-row self-aligning ball bearing with a spherical outer-ring raceway to accommodate misalignment and shaft deflection.
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.
50x90x51.6 mm
UC 210 URB insert ball bearing is a sealed housing bearing with a spherical outside surface and extended inner ring. It is secured to a 50 mm shaft by two set screws. The design accommodates minor initial mounting misalignment inside a compatible housing.
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.
50x90x20 mm
The 6210 N KINEX deep-groove ball bearing is a single-row radial bearing with a snap-ring groove in the outer ring. The groove simplifies axial location in the housing, while the deep raceways support radial loads and moderate axial forces in both directions.
This open, unsealed design is suitable for gearboxes, electric motors and industrial positions with a separate lubrication system.
1210 K ZKL self-aligning ball bearing has two rows of balls, a spherical outer-ring raceway and a tapered bore. It accommodates angular misalignment between shaft and housing and can be mounted directly on a tapered journal or with a matching adapter sleeve.
The 6210 2Z P6 ZKL deep-groove ball bearing is a single-row radial bearing with non-contact metal shields on both sides. The shields help retain lubricant and restrict common contaminants while maintaining low running friction.
Suitable for electric motors, fans, pumps, gearboxes, conveyors and other rotating equipment. The 2Z suffix denotes two metal shields; the bearing is not watertight. Accuracy class P6 provides tighter dimensional and running tolerances than the normal class.
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.
50x90x21.75 mm
Single-row tapered roller bearing 30210 A P6X ZVL for high radial loads and axial load in one direction. The P6X tolerance version is intended for arrangements with higher accuracy requirements; the complete A P6X designation must match when replacing the bearing.
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.
50x90x20 mm
Rubber seals on both sides
Single-row deep-groove ball bearing 6210 2RSR ZVL for radial load and moderate axial loads in both directions. Contact rubber seals on both sides retain lubricant and protect the rolling elements from dust, contaminants and splashing moisture.
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.
