45x100x25 mm
KINEX 6309 2RS single-row deep-groove ball bearing with rubber seals on both sides.
For radial loads and limited axial loads in either direction.
50x58x25 mm
Single-row INA HK5025 drawn cup needle roller bearing with open ends and cage, designed for high radial loads in a compact radial envelope. The unsealed version is suitable for grease or oil lubrication.
70x110x25 mm
Robust single-row tapered roller bearing 32014 AX KLF ZVL for combined radial and one-direction axial loads. Its separable design simplifies installation and allows precise adjustment of operating clearance or preload.
45x100x25 mm
6309 2RS1 SKF deep-groove ball bearing is a single-row radial bearing with contact seals on both sides. It carries radial loads and moderate axial forces in either direction. The 2RS1 design protects the internal rolling contact from contaminants and helps retain lubricant inside the bearing.
55x63x25 mm
The HK 5525 ZEN drawn-cup needle roller bearing is a thin-walled, open-ended bearing without an inner ring. It provides high radial load capacity where radial installation space is very limited.
The shaft acts directly as the inner raceway and therefore requires suitable hardness, accuracy and surface finish. This bearing does not provide axial location.
75x130x25 mm
Single-row cylindrical roller bearing NU 215 ZKL for high radial loads and accurate shaft guidance. The NU design permits axial displacement of the shaft relative to the housing in both directions; when replacing, compare the complete designation and required internal clearance.
35x100x25 mm
Single-row cylindrical roller bearing NJ 407 ZKL for high radial loads with axial shaft location in one direction. The NJ design permits axial displacement in the opposite direction; when replacing, compare the complete designation and required internal clearance.
45x100x25 mm
ZKL 1309 self-aligning ball bearing with two rows of balls compensates minor shaft-to-housing misalignment. It is intended mainly for radial loads and limited axial loads in both directions.
75x130x25 mm
Bearing 6215 2RS ZVL with rubber seals on both sides for use in machinery and equipment.
Rubber seals on both sides

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.
