Exact replacement needed

Saved me from buying expensive OEM parts. The dimensions matched the 6205 specification perfectly. Very satisfied with the purchase.

Great for marine equipment

Used these on my boat trailer wheels. They handle the saltwater exposure much better than standard carbon steel bearings. Smooth rotation after several months.

Corrosion resistance is real

Working in a humid environment where rust is a constant issue. These stainless steel bearings have shown no signs of oxidation since installation.

Good quality overall

Fit perfectly into my machinery housing. The only reason for 4 stars is the packaging was slightly dented upon arrival, but the bearings were unaffected.

Smooth operation

Took a few hours to break in, but now they run very quietly. Good value for the price compared to local suppliers.

5 FAQ

Q: Can you confirm the dimensions for the 6203 model?

A: Yes, the 6203 bearing has an inner diameter of 17mm, an outer diameter of 40mm, and a width of 12mm.

Q: What is the maximum RPM for the 6203 size?

A: The limiting speed varies by lubrication and load, but generally, the 6203ZZ can handle up to 18,000 RPM under light load conditions.

Q: What is the difference between 304 and 440 stainless steel for these bearings?

A: 304 offers better general corrosion resistance, while 440 is harder and provides better wear resistance. Both are rust-resistant compared to carbon steel.

Q: Is the pre-greased lubrication suitable for high temperatures?

A: The standard grease is suitable for the stated operating temperature range of -20°C to 120°C. For higher temps, regreasing with high-temp lubricant is recommended.

Q: Are these bearings completely waterproof?

A: They are water-resistant due to the stainless steel material and ZZ shields, but they are not designed for continuous submersion in liquids.
