TIMKEN 6004-2RS Double Rubber Seal Bearings — 20x42x12 mm (Pack of 2)

A grinding or whining noise from a rotating component, play you can feel by hand, a hot housing, or grease leaking past a damaged seal — a worn ball bearing announces itself early. Ignore it, and it can damage the shaft or housing. Replacing worn bearings with this pack of two TIMKEN 6004-2RS bearings ensures smooth operation, stable performance, and cost-effective reliability.

These are TIMKEN 6004-2RS single-row deep groove radial ball bearings with double rubber contact seals (2RS). They are pre-lubricated at the factory with high-quality grease for long-lasting, maintenance-free operation. The rubber seals protect the bearing from dust, dirt, and moisture while retaining the grease inside. This listing includes two bearings.

When to Replace

• Grinding, whining, or rumbling noise from the bearing location
• Noticeable play or wobble in the shaft
• Housing running hot
• Grease leaking past a torn or damaged seal
• A bearing removed from a shaft should always be replaced — never reinstall a used bearing

FAQ

FAQ

Is this the same as SKF 6004-2RS1 or NSK 6004DDU?
They are dimensional equivalents: the same 6004 size (20 × 42 × 12 mm) with two rubber seals. The suffixes 2RS, 2RS1, DDU, LLU, 2RSR, and 2NSE all denote the same seal configuration across brands. They interchange by size, but they are different manufacturers' parts.

What does "2RS" mean?
Two rubber contact seals — one on each side of the bearing. They keep the factory grease in and contamination out.

Do I need to grease it?
No. The bearing comes pre-greased and sealed; it is not designed to be re-lubricated.

Can I reuse a bearing after pulling it off a shaft?
No. A bearing removed from a shaft should be replaced — reinstalling it risks early failure.

How many bearings do I get?
Two TIMKEN 6004-2RS bearings are included in this listing.

How do I know this is the right size?
Check the number stamped on your old bearing: 6004-2RS, or any of the interchange numbers listed above, confirms the fit.

What is the maximum speed I can run this bearing at?
The reference speed is ~13,000–20,000 rpm for grease lubrication, but the maximum safe speed depends on load, temperature, and application conditions. Consult your equipment manual for guidance.

Can this bearing handle axial load?
Yes — deep groove ball bearings can handle moderate axial loads, but they are primarily designed for radial loads.

Does this bearing come with rubber seals or metal shields?
This is the 2RS version with rubber seals. If you need metal shields, look for the ZZ version (e.g., TIMKEN 6004-ZZ).

Is this a good value for the money?
Yes — this 2-pack offers two high-quality TIMKEN bearings at a cost-effective price, making it an economical choice for maintenance and repairs.

Product Type
Deep Groove Radial Ball Bearing (single row, double sealed)

Function
Supports a rotating shaft while carrying radial load (and limited axial load). The two rubber contact seals retain the factory grease fill and block dust and moisture, so the bearing runs maintenance-free for its service life.

Applications
This bearing fits by size, not by vehicle: it replaces any bearing of the standard 6004-2RS specification (20 × 42 × 12 mm, double sealed). Typical uses include electric motors, power tools, automotive alternators, pumps, household appliances, and general industrial machinery.

Important: Match the number stamped on your old bearing (6004-2RS or an equivalent from the interchange list above). Please verify the required bearing size before ordering.
