45x85x19 mm
ZKL 6209 K bearing with verified mounting dimensions; compare the complete K suffix before replacement.
45x85x19 mm
Single-row 6209 2RS ZKL deep groove ball bearing with contact rubber seals on both sides. It carries radial and limited axial loads in both directions; the seals retain lubricant and protect the rolling contact from contaminants.
45x85x20.75 mm
30209 A KLF-ZVL tapered roller bearing for combined radial and axial loads.
45x85x19 mm
6209 2RS SKF deep-groove ball bearing with rubber seals on both sides.
45x75x16 mm
FAG single-row deep groove ball bearing with metal shields on both sides (2Z).
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.
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.
45x85x19 mm
1209 MGM is a double-row self-aligning ball bearing with a cylindrical bore. The spherical outer-ring raceway allows the bearing to accommodate angular misalignment and shaft deflection without excessive edge loading.
It is particularly suitable where perfect alignment between shaft and housing cannot be guaranteed. The bearing supports radial load and lighter axial loads in both directions.
45x75x16 mm
6009 2RS ZKL is a single-row deep-groove ball bearing with contact seals on both sides. The seals help retain lubricant and protect the rolling space from dust, moisture and other common contaminants.
Its versatile design supports radial load and moderate axial loads in both directions. It is well suited to applications where dependable bearing protection and low maintenance requirements are important.
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.
45x75x16 mm
6009 2RS C3 ZKL deep-groove ball bearing is a single-row radial bearing with rubber seals on both sides. It carries radial loads and moderate axial forces in either direction. The 2RS design helps protect the internal rolling contact from dust and moisture while retaining lubricant inside the bearing. C3 radial internal clearance is greater than normal, providing extra allowance for thermal expansion or tighter fits; it must match the machine design.
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.
45x85x30 mm
Double-row angular contact ball bearing 3209 ZKL for combined radial loads and axial loads in both directions. A robust solution for arrangements requiring good rigidity and accurate shaft guidance.
45x75x20 mm
Single-row tapered roller bearing 32009 AX ZKL for high radial load combined with axial load in one direction. Its separable design allows the inner ring with rollers and the outer ring to be mounted independently.
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.
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.
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.
