55x100x21 mm
Single-row SKF 6211 2RS C3 deep-groove ball bearing
Rubber seals on both sides; C3 means greater radial internal clearance, so verify suitability.
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.
65x100x18 mm
ZKL 6013 single-row deep-groove ball bearing in an open design.
For radial loads and limited axial loads in either direction.
65x100x18 mm
ZVL 6013 2RS single-row deep-groove ball bearing with rubber seals on both sides for improved protection of the lubricant and raceways in normally dusty or damp operation.
45x100x27.25 mm
30309 A ZVL is a single-row tapered roller bearing for combined radial and axial loads. Its separable design simplifies mounting and precise adjustment of clearance or preload.
45x100x39 mm
3309 BD XL 2HRS TVH FAG double-row angular contact ball bearing in X-life performance design, sealed on both sides and fitted with a plastic cage.
45x100x39.7 mm
3309 ZKL double-row angular-contact ball bearing carries high radial loads together with axial forces in both directions. Two ball rows provide rigid axial location and the ability to support tilting moments in a compact unit. It suits positions where a single-row ball bearing does not provide sufficient axial capacity.
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.
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.
45x100x27.25 mm
31309 A FLT single-row tapered roller bearing carries high radial load together with axial load in one direction. Its separable inner assembly with rollers and separate outer ring simplify mounting.
45x100x25 mm
ZKL bearing for industrial applications. When replacing a part, always verify the complete designation, dimensions, design and application requirements against the manufacturer documentation.
Rubber seals on both sides
65x100x27 mm
ZKL 51213 A 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.
45x100x38.25 mm
ZKL 32309 BA C6 bearing. Verify the complete designation and dimensions in manufacturer documentation before selection.
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.
