Parts supplied from our European supplier

They normally dispatch within 7–10 working days, and are then sent on by express courier like anything else. Nothing ships to you direct from Germany — it comes to our Arlesey workshop first, so you deal only with us for returns and warranty.

KBS 6004-2RS deep groove ball bearing with rubber seals on both sides (2RS suffix). Measuring 20mm inner diameter × 42mm outer diameter × 12mm width. A standard and widely used bearing size in gearbox, differential, and drivetrain rebuild applications.
Specifications:
- Brand: KBS
- Part Number: 6004-2RS (also listed as 60042RS)
- Inner Diameter (d): 20 mm
- Outer Diameter (D): 42 mm

What is the KBS 6004-2RS used for in gearbox applications?
The 6004-2RS is a common general-purpose deep groove bearing used in manual gearbox and differential bearing positions where a 20mm bore, 42mm OD bearing with 2RS sealing is specified. It is used across a wide variety of transmission designs from various manufacturers.
Is the 6004-2RS the same size as a 6004-ZZ?
Yes — the 6004-2RS and 6004-ZZ are identical in dimensions (20x42x12mm). The difference is sealing type: 2RS uses rubber contact seals, while ZZ uses metal shields. For most gearbox applications, 2RS is preferred for better contamination exclusion.
How does the 6004-2RS differ from the 6005-2RS?
The 6004-2RS has a 20mm bore versus 25mm on the 6005-2RS. The outer diameters are also different (42mm vs 47mm). These two bearings are not interchangeable. See ET2825 for the 6005-2RS (25x47x12mm).
What quality standard does the KBS 6004-2RS meet?
KBS bearings are manufactured to ISO dimensional tolerances, making them dimensionally interchangeable with equivalent bearings from any major manufacturer. Suitable for general gearbox rebuild use where a cost-effective quality bearing is required.
How do I confirm this bearing fits my gearbox?
Measure the shaft diameter (bore) and housing bore from your existing bearing, or reference the bearing number from your workshop manual. The KBS 6004-2RS fits any application calling for a 20x42x12mm deep groove ball bearing.
