SEO-Optimized Product Description

The 6003 2RS C3 FAG 17x35x10 is a precision-engineered, sealed deep groove ball bearing that combines reliable performance, robust sealing, and a superior internal clearance profile. Internally referred to as a 6000-series deep groove bearing, this model includes double rubber seals (2RS) and C3 internal clearance, making it ideal for applications requiring both protection from contaminants and allowance for thermal expansion.

Key Dimensions & Features

• Inside diameter (d): 17 mm

• Outside diameter (D): 35 mm

• Width (B): 10 mm

• Sealing type: 2RS (rubber seals on both sides)

• Internal clearance: C3 (greater than normal)

• Bearing type: Single-row deep groove ball bearing

• Brand: FAG (Schaeffler)

• Cage material: Steel pressed cage

• Material: High-grade chromium bearing steel

• Typical dynamic load rating: ~ 6.4 kN

• Typical static load rating: ~ 3.25 kN

• Limiting speed (approx): ~ 11,800 rpm

• Operating temperature range: -30 °C to +110 °C (depending on seals & grease)

Because of the C3 clearance, this bearing accommodates slight thermal expansion and is less prone to seizing under higher temperature or high-speed operations. The 2RS rubber seals protect against dust, moisture, and foreign particles, giving added reliability in less-than-ideal environments.

Applications & Use Cases

This bearing is well-suited for a wide range of industrial and mechanical applications, such as:

• Electric motors, alternators, and generators

• Pumps, compressors, and fans

• Gearboxes, reducers, and drives

• Precision machinery, robotics, and automation

• Household appliances and power tools

• Industrial equipment requiring sealed bearings

Its sealed design (2RS) makes it particularly suitable in settings where ingress of contaminants is a concern, while still maintaining smooth rotation and durability.

Advantages & Competitive Strengths

• Sealed on both sides (2RS) - prevents infiltration of dust, moisture, and contaminants

• Internal clearance C3 - allows for thermal expansion and stable operation in warmer conditions

• Reliable brand FAG - recognized for consistency and high quality

• Common dimensions 17x35x10 mm - easy to integrate and replace in many applications

• Good balance between sealing and friction - well suited for many load & speed ranges

• Drop-in replacement - versatile option for maintenance or redesign

Installation & Maintenance Tips

• Ensure shaft and housing surfaces are clean, within tolerance, and free of burrs

• Use correct pressing tools or sleeve-driven installation to prevent ring or seal damage

• Since 2RS bearings are pre-lubricated (sealed), relubrication is generally not needed

• Monitor temperature, vibration, and noise in critical systems

• Avoid impact or shock loads during assembly

FAQ - Frequently Asked Questions

Q1: What does “2RS” mean in 6003 2RS C3?
“2RS” indicates that the bearing has rubber seals on both sides, offering protection against dust, moisture, and contaminants while maintaining smooth rotation.

Q2: Why choose C3 internal clearance?
A C3 clearance is greater than a standard (normal) internal clearance. It allows for thermal expansion and is advantageous in applications with higher temperatures or tight fits.

Q3: Can 6003 2RS C3 FAG replace a standard 6003 2RS (without C3)?
Yes, in many cases, but ensure the added clearance doesn’t adversely affect alignment or stability in your specific arrangement.

Q4: What is typical speed capability of this bearing?
With proper lubrication and conditions, the limiting speed is around 11,800 rpm for this model.

Q5: What are load capacities of 6003 2RS C3?
Dynamic load capacity is approximately 6.4 kN, and static load capacity approx. 3.25 kN for the sealed variant.

Q6: Can the seals be removed to convert to an open bearing?
In some cases, rubber seals can be carefully removed if the design requires, but this must be done with extreme caution to avoid damage.
