20x42x12 mm
6004 2Z ZVL single-row deep groove ball bearing with non-contact metal shields on both sides. Suitable for radial and moderate axial loads in both directions, combining low friction with protection of the lubricant from larger contaminants.
20x42x12 mm
Single-row 6004 2RS SKF deep-groove ball bearing
Rubber seals on both sides; compare the complete designation before ordering.
20x42x12 mm
BMZ 6004 bearing with clearly stated mounting dimensions. The product name gives no suffix for closure or clearance; compare the complete marking on the original bearing before replacement.
20x42x12 mm
Single-row SKF Explorer 6004 2RSH deep groove ball bearing with low-friction seals on both sides and normal CN radial clearance. It carries radial and axial loads in both directions, is grease lubricated and requires little maintenance.
35x42x20 mm
MTM HK 3520 drawn-cup needle roller bearing with open ends and no inner ring. A compact design for high radial loads where radial installation space is limited.
20x42x12 mm
Greater C3 radial internal clearance. ZKL single-row deep groove ball bearing for arrangements requiring increased clearance.
25x42x17 mm
DKF NU 4905 single-row cylindrical roller bearing in NU design for high radial loads. The outer ring has two integral flanges and the inner ring has no flanges, allowing axial displacement of the shaft relative to the housing in both directions.
15x42x13 mm
KINEX 6302 2RS single-row deep-groove ball bearing with contact rubber seals on both sides. The closed design helps retain lubricant and protects the raceways from contamination and moisture.
25x42x9 mm
61905 2RS1 SKF thin-section deep-groove ball bearing with contact seals on both sides for compact arrangements and effective lubricant protection.
15x42x17 mm
2302 2RS ZVL self-aligning ball bearing is a double-row bearing with a spherical outer-ring raceway and rubber seals on both sides. It accommodates moderate shaft-to-housing misalignment while carrying radial loads and light axial forces in either direction.
25x42x9 mm
The 61905 2RS KINEX thin-section deep-groove ball bearing is a compact single-row bearing with contact rubber seals on both sides. It combines a small radial cross-section and low weight with the ability to support radial loads and moderate axial forces in both directions.
Suitable for small electric motors, instruments, gearboxes, robotics and other mechanisms with restricted radial space.
25x42x20 mm
The GE 25 E 2RS ZVL radial spherical plain bearing has spherical sliding surfaces and rubber seals on both sides. It accommodates oscillating movement and misalignment while supporting high radial and combined loads.
Suitable for hydraulic cylinders, linkages, articulated mechanisms, agricultural and construction machinery. Its steel sliding surfaces require appropriate lubrication.
HK 3520 CX drawn-cup needle roller bearing is an open-ended, thin-walled bearing without an inner ring. It provides high radial load capacity in a very small radial space; a suitably hardened and precision-ground shaft forms the inner raceway.
2302 2RS CODEX self-aligning ball bearing has two rows of balls and a spherical raceway in the outer ring, allowing it to compensate for angular misalignment between the shaft and housing. Rubber seals on both sides protect the factory grease and the bearing interior against common contaminants.
Practical advice
How to choose the right bearing
The same dimensions do not necessarily mean the same function. When selecting a replacement, check the construction, cover and seal design, internal clearance, and the conditions in which the bearing will operate.
Determine the type and size
Copy the full type designation. If missing, measure the inner diameter d, outer diameter D and width B.
Check the design
Distinguish open bearing, metal shields, and rubber seals. Also check internal clearance, accuracy, cage, and lubricant.
Take operating conditions into account
Rotational speed, direction, and magnitude of mechanical load, temperature, humidity, dust, and the method of installation are decisive.
How to read the type designation 6204 2RS C3
Suffixes may vary between manufacturers. When replacing, compare technical parameters, not just similar type designation.
Open, 2Z, or 2RS?
When are matching dimensions not enough?
A dimensionally identical bearing may have different load capacity, maximum speed, precision, or internal clearance. Pay special attention to electric motors, high temperatures, vibrations, shocks, and dusty or humid environments.
- radial, axial, and combined loads
- normal or increased internal clearance C3/C4
- operating temperature and maximum speed
- design of shields and seals, lubricant, cage material, and precision
Frequently asked questions
Can I replace a bearing with another brand?
Usually yes, if the design type, dimensions, internal clearance, precision, cover and seal design, load capacity, and allowable speeds match. The basic number alone is not enough; the meaning of the suffixes may vary according to the manufacturer.
How do I determine the diameter of the inner bore from the model designation?
For many common metric bearings, the bore diameter code from 04 is multiplied by five: for example, 04 = 20 mm and 06 = 30 mm. Codes 00 to 03 and some special designs have different rules, so it is advisable to verify the dimension.
Is 2RS better, or 2Z?
Neither is universally better. 2RS usually protects better against dirt and moisture, while 2Z tends to have lower friction and allows higher speeds. The right choice depends on the application.
What to send if the type designation is unreadable?
A photo of both sides, dimensions d × D × B, machine type, and information about speed, load, temperature, humidity, or dustiness. The more operational data we know, the more safely a replacement can be recommended.
Not sure about the replacement?
Send the type designation, dimensions, or a photo of the original part. We will help verify the suitable version before ordering.
