Bearings

Selection without unnecessary searching

Find the right bearing on the first try

Do you know the bearing designation? Search, for example, for 6204 2RS C3. If the designation is unreadable, just the dimensions are enough d × D × B, photos and a brief description of use.

Three dimensions you need

dinner diameter
Douter diameter
Bbearing width

Measure in millimeters, ideally with a caliper.

01 · Known type designation

Copy the entire type designation including suffixes, for example 2RS, 2Z, C3. Each can change the design of the bearing.

02 · I only have dimensions

Measure the bore diameter, outer diameter, and width. Add the machine type and information about mechanical load or RPM.

03 · I need a replacement

Photograph both sides of the old part and the visible designation. We will help verify both common and less common designs.

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.

1

Determine the type and size

Copy the full type designation. If missing, measure the inner diameter d, outer diameter D and width B.

2

Check the design

Distinguish open bearing, metal shields, and rubber seals. Also check internal clearance, accuracy, cage, and lubricant.

3

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

6Single-row deep groove ball bearing
2bearing size series
04bore diameter code; in common type designation it corresponds to 20 mm
2RSrubber seal on both sides
C3larger internal clearance than normal; not automatically suitable for every application

Suffixes may vary between manufacturers. When replacing, compare technical parameters, not just similar type designation.

Open, 2Z, or 2RS?

Open design Without protective shields and seals, suitable where the bearing is protected by the structure or lubricated from the outside.
Z, 2Z or ZZ Metal protective shield on one or both sides. It has low friction and mainly protects against larger contaminants.
RS or 2RS Rubber seal on one or both sides. It better prevents dust and moisture, but usually creates higher friction.

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.
