6003 2RS FG KOYO 17x35x10 Deep Groove Ball Bearing

6003 2RS FG KOYO 17x35x10 - Deep Groove Ball Bearing

KOYO 6003 2RS FG is a single-row deep groove ball bearing with dimensions 17x35x10 mm and contact seals on both sides. The FG version uses a glass-fibre reinforced PA66 polyamide cage guided by the rolling elements. The 6003 bearing belongs to the compact 60 series of deep groove ball bearings.

6003 2RS FG KOYO - Technical Data

Dimensions of 6003 2RS FG KOYO

The principal bearing dimensions are:

17x35x10 mm

where:

• d: 17 mm - bore diameter

• D: 35 mm - outside diameter

• B: 10 mm - bearing width

JTEKT confirms these dimensions for the KOYO 6003 2RS bearing.

6003 Deep Groove Ball Bearing Design

6003 is a single-row deep groove ball bearing.

Deep groove ball bearings are designed primarily to accommodate radial loads, while the deep raceway geometry also enables them to support axial loads in both directions within the operating limits of this bearing design.

The 6003 series combines compact dimensions with the ability to operate at relatively high rotational speeds.

What Does 2RS Mean?

The designation:

2RS

indicates that the bearing is sealed on both sides.

JTEKT classifies the KOYO 6003 2RS as:

contact sealed

The two seals help to:

• retain lubricant inside the bearing

• limit the ingress of dust and contamination

• protect the rolling elements and raceways

• reduce exposure of the internal bearing components to the external environment

What Does FG Mean in KOYO 6003 2RS FG?

The suffix:

FG

identifies a version using a cage manufactured from:

glass-fibre reinforced PA66 polyamide

The cage is guided by the rolling elements.

The complete product identification is therefore:

6003 2RS FG KOYO 17x35x10 mm

The FG suffix is relevant when searching for or replacing this exact bearing version.

Internal Clearance - Important Difference

The designation:

6003 2RS FG

should not automatically be treated as equivalent to:

6003 2RS C3 FG

These are different bearing variants.

6003 2RS FG

• dimensions 17x35x10 mm

• sealed on both sides

• FG cage

• normal internal clearance

6003 2RS C3 FG

• dimensions 17x35x10 mm

• sealed on both sides

• FG cage

• C3 internal clearance

C3 means that the radial internal clearance is greater than normal.

If the bearing or packaging is marked only 6003 2RS FG, the C3 suffix should not be added.

Load Ratings

According to JTEKT technical data for the 6003 2RS:

Basic dynamic load rating Cr: 7.50 kN

Basic static load rating C0r: 3.25 kN

Fatigue load limit Cu: 0.170 kN

These parameters are important when calculating bearing suitability and service life for a specific application.

Limiting Speed

JTEKT specifies a limiting speed for 6003 2RS of:

12,000 rpm with grease lubrication

The actual permissible operating speed in a specific application may also depend on:

• bearing load

• operating temperature

• shaft and housing fits

• lubrication conditions

• alignment

• surrounding components

• overall bearing arrangement

Mounting Dimensions

JTEKT data for 6003 2RS includes the following mounting dimensions:

• da min.: 19 mm

• da max.: 21 mm

• Da max.: 33 mm

• ra max.: 0.3 mm

These dimensions are relevant when designing or checking the shaft and housing shoulders adjacent to the bearing.

Bearing Mass

The reference mass of the KOYO 6003 2RS is approximately:

0.039 kg

or approximately:

39 g

6003 2RS FG vs 6003 2RS C3 FG

Both versions have the same basic dimensions:

17x35x10 mm

However, they differ in internal clearance.

6003 2RS FG

• 17x35x10 mm

• double sealed

• FG cage

• normal internal clearance

6003 2RS C3 FG

• 17x35x10 mm

• double sealed

• FG cage

• C3 internal clearance greater than normal

For this reason, the C3 suffix is technically significant and should not be ignored when selecting a replacement.

Selecting a Replacement

Before selecting an alternative to KOYO 6003 2RS FG, verify:

1. 6003 bearing designation.

2. Bore diameter 17 mm.

3. Outside diameter 35 mm.

4. Width 10 mm.

5. Contact seals on both sides.

6. Cage construction.

7. Required internal clearance.

8. Required load ratings.

9. Operating speed.

10. Temperature and environmental conditions.

Particular attention should be paid to the difference between normal internal clearance and C3 clearance.

FAQ

What are the dimensions of KOYO 6003 2RS FG?

The bearing has dimensions of 17x35x10 mm: 17 mm bore diameter, 35 mm outside diameter and 10 mm width.

What type of bearing is KOYO 6003?

6003 is a single-row deep groove ball bearing.

What does 2RS mean?

2RS indicates seals on both sides. JTEKT classifies the 6003 2RS as a bearing with contact seals.

What does FG mean in a KOYO bearing?

FG identifies a version with a glass-fibre reinforced PA66 polyamide cage, guided by the rolling elements.

Does 6003 2RS FG have C3 clearance?

C3 should not be assumed. A bearing marked 6003 2RS FG should not automatically be described as C3. The increased-clearance version is designated 6003 2RS C3 FG.
