6003-2RS Single Row Chrome Steel Ball Bearing
A Common Bearing Size for General Industrial Equipment
The 6003-2RS is a single row deep groove ball bearing with rubber seals on both sides. It is a common size used in motors, rollers, small machines, and many general mechanical assemblies.
The bearing has a 17 mm bore, 35 mm outside diameter, and 10 mm width. The compact size makes it easy to install in equipment where space is limited.
For replacement buyers, 6003-2RS is often selected because the size is widely used and easy to match with existing equipment.

What the 2RS Seal Means
The 2RS code means the bearing has rubber seals on both sides.
These seals help keep common dust and moisture away from the internal raceway and grease. This makes the bearing suitable for many machines where the bearing is not fully exposed to heavy contamination.
For buyers choosing between open, shielded, and sealed versions:
| Version | Main Feature |
|---|---|
| Open | Easy to relubricate, but no protection from dust |
| ZZ / 2Z | Metal shields on both sides |
| 2RS | Rubber seals on both sides |
The right choice depends on the machine environment and operating speed.
Why 6003-2RS Is Used in Many Machines
This bearing size is useful for general-purpose applications because it combines a relatively small outside diameter with a standard 17 mm bore.
It can be used in equipment such as:
Electric motors
Rollers
Small pumps
Fans
Gearboxes
Conveyor equipment
Workshop machinery
Agricultural equipment
It is also commonly kept as a replacement part by maintenance teams and bearing distributors.
Chrome Steel for General Industrial Use
The rings and balls are made from chrome bearing steel. This material is widely used for standard industrial bearings because it provides good hardness and wear resistance.
For normal operating conditions, the bearing can provide stable running performance when properly installed and used within its load and speed limits.
The bearing is pre-greased before delivery, so no initial lubrication is normally required.
