Product Overview
The 6204 2RS bearing is a single-row deep groove ball bearing with contact rubber seals on both sides, engineered for the 20 mm shaft class. It handles radial loads and moderate axial loads in both directions, and the fully sealed construction protects the raceways from contamination while holding lubrication in place. The 6204-2RS is a frequent replacement item in gearboxes, electric motors, blowers and automotive accessory drives where reliability matters more than top-end speed. Produced from chrome steel with a pressed steel cage, it delivers quiet, maintenance-free operation over a long service life. The 6204RS bearing matches major brand equivalents dimensionally and is stocked in standard and C3 clearance versions.

All dimensions and tolerances conform to ISO 492 and ISO 15 rolling bearing standards, ensuring interchangeability and consistent fit across global supply chains. This model is equivalent to the SKF 6204-2RS1 designation.
Features and Benefits
- Contact rubber seals on both sides — keeps grease in and blocks dust, water and debris, longer service life with less maintenance.
- Deep groove raceway design — supports radial and moderate axial loads in both directions, one bearing covers most shaft load conditions.
- Chrome steel (GCr15) rings and balls — high hardness and dimensional stability, consistent performance under continuous operation.
- Pressed steel cage — quiet running with reliable ball guidance, low noise in motor and fan applications.
- ISO 15 boundary dimensions — matches major brand equivalents exactly, drop-in interchangeability for replacements.
Applications
Gearboxes & Transmissions
The sealed 6204 2RS bearing handles combined radial and axial loads in compact gear drives, and the rubber seals keep gearbox oil and debris away from the raceways.
- Small industrial gearboxes
- Electric actuators
- Transmission shafts
- Winches and hoists
Electric Motors & Blowers
Motor manufacturers specify the 6204-2RS for its low noise and long sealed life; it is a direct drop-in replacement in fractional-horsepower motors and centrifugal blowers.
- Fractional-horsepower motors
- Centrifugal blowers
- Compressors
- Cooling fans
Household Appliances & Automotive
For high-volume OEM and aftermarket programs, the 6204 2RS bearing delivers consistent quality at scale and interchanges with our other deep groove ball bearings across the 62 series.
- Washing machines and dryers
- Vacuum cleaners
- Alternators and starter motors
- Power steering pumps
Quality and Manufacturing
Each 6204 2RS bearing is manufactured from GCr15 chrome steel to ISO 492 P0 tolerance class. Rings and balls are ground to specification, and every bearing is inspected for radial internal clearance, running noise and seal integrity before it is packed and shipped.

Frequently Asked Questions
What are the dimensions of a 6204 2RS bearing?
A 6204 2RS bearing has a 20 mm bore, a 47 mm outside diameter and a 14 mm width (20×47×14 mm), with contact rubber seals on both sides.
What is the difference between a 6204 2RS and a 6204 ZZ bearing?
6204 2RS uses rubber contact seals for maximum protection against dust and moisture, while 6204 ZZ uses metal shields for lower friction and higher speed. For most industrial replacement work, the sealed 2RS version is the safer choice.
Is 6204RS the same as a 6204 2RS bearing?
Yes. 6204RS and 6204 2RS are alternative spellings of the same bearing — a 6204 deep groove ball bearing with rubber seals on both sides. SKF writes 6204-2RS1 and NSK writes 6204DDU.
What is the load rating of a 6204 2RS bearing?
The basic dynamic load rating (Cr) of the 6204 2RS bearing is 12800 N and the basic static load rating (C0r) is 6650 N, per the manufacturer’s specification sheet.
What is the speed rating of a 6204 2RS bearing?
With grease lubrication the 6204 2RS bearing is rated for 14000 rpm; with oil-bath lubrication the rated speed increases to 17000 rpm.
Can a 6204 2RS bearing be used in an electric motor?
Yes — the 6204 2RS bearing is one of the most common sealed bearings used in fractional-horsepower electric motors, where its low noise and contamination resistance extend motor service life.
Where is a 6204 2RS bearing commonly used?
Gearboxes, electric motors, blowers, household appliances, automotive accessory drives and general industrial equipment are the most common applications for the 6204 2RS bearing.
