Decoding SKF 6004-RSH
- 60Series
- Deep groove ball bearings, 60 series. Series differ in outside diameter and width even when the bore is the same.
- 04Bore
- Bore 20 mm (04 × 5).
- RSHSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6004 is the standard ISO basic designation, which sets the bearing type, series and bore.

Single-row deep groove ball bearings from SKF that carry moderate radial and axial loads in either direction. The RSH feature is an elastomer seal fitted to one side; it keeps lubricant in and contaminants out. Typical installations include electric motors, fans, pumps, portable power tools and general industrial machinery.
Reading the code tells you which version you have. The base number sets the size and series, and the suffix shows the sealing arrangement: in 607-2RSH the 607 is the size reference while 2RSH means both sides are sealed; in 608-RSH the RSH suffix means only one side carries a seal. The same logic applies across 609-2RSH, 626-2RSH, 627-2RSH and 629-2RSH, where the leading digits fix the dimensions and the suffix fixes the protection.
Where do these bearings fit? Low and medium power electric motors, fans, centrifugal pumps, compressors, machine tools and transmission equipment are common hosts, along with appliances, refrigeration units and light conveying systems. Their compact envelope and moderate-speed capability suit food, textile, automotive and metalworking plants as well as maintenance shops.
Selection comes down to three things: the radial and axial load, the running speed and the surrounding conditions. Choose RSH sealing where dust, moisture or splashing liquids are present; in a clean environment where lower friction matters, an open or shielded version may serve better. During mounting, confirm that shaft and housing are aligned and avoid impacts that could deform the seals. The bearing arrives pre-lubricated, so leave the grease as supplied unless the manufacturer states otherwise, and aim for moderate interference on the inner or outer ring so the fit seats correctly.
Replacing a bearing from a different maker is often straightforward: the base number plus the sealing type usually match across brands. A 2RS part from another supplier may line up with an SKF 2RSH, but verify tolerances and clearance before committing. MR Industrial Accessories LLC supplies SKF bearings and can advise on interchangeability; send the full code, or the shaft and housing dimensions, and we will point you to the compatible option.
To get a quote, message us on WhatsApp or by email with the exact code printed on the bearing, or the dimensions you need. If the designation is unclear, a photo or the equipment data is enough for us to help identify the correct replacement. We serve customers throughout the United States and in several Latin American countries.

Frequently asked questions
- SKF 6004-RSH bearing: what are its dimensions?
- SKF 6004-RSH measures 20 mm across the bore and 42 mm across the outside diameter; its width is 12 mm (20 x 42 x 12 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6004.
- What does RSH mean on an SKF bearing?
- It means an elastomer seal is fitted to one side. The 2RSH version seals both sides. The seal blocks contaminants and holds the lubricant in place, which suits dusty or moderately humid conditions.
- How do I request a quote for an SKF RSH bearing?
- Send the complete code from the bearing, such as 608-2RSH, or the shaft and housing dimensions, through WhatsApp or email. Our team replies promptly. If the code is not clear, a photo helps us identify the part.
- Can another brand's bearing replace an SKF RSH?
- Usually yes. Deep groove ball bearings with 2RS sealing from other makers tend to interchange with SKF 2RSH when dimensions and clearance agree. Send us the original code and we will confirm the equivalent.
