608 deep groove ball bearing commonly uses the size 8x22x7mm. S608 usually refers to the stainless steel version of 608. The size system can be the same, but the material and suitable working environment are different.

Where 608 is commonly used

608 is widely used in motors, pulleys, tools, mechanical transmission and automation equipment. Bearing steel versions are common for normal environments.

Where S608 is more suitable

S608 can be considered when anti-rust, cleaner use or some corrosion resistance is needed. For stainless steel bearing inquiries, 440C can be used as the main material reference.

What to confirm before ordering

  • Confirm whether bearing steel 608 or stainless steel S608 is required.
  • Confirm sealing type: ZZ, RS or open.
  • Confirm moisture, dust, cleaning or anti-rust requirements.
