The SKF 6300 2RS C3 is a premium sealed deep groove ball bearing, classically dimensioned at 10 mm inner diameter, 35 mm outer diameter, 11 mm width. This model is highly sought in global searches such as “6300 2RS C3 bearing,” “SKF 6300 sealed bearing,” “6300 C3 10x35x11,” “deep groove bearing 6300 2RS,” and “SKF 6300 2RS C3 industrial bearing.”
Thanks to its 2RS rubber seals on both sides, the bearing is protected from dust, moisture, and contamination, making it ideal for harsh environments or applications requiring long-term reliability. The C3 internal clearance gives added room between the rings and cage, allowing for thermal expansion or slight axial displacement without binding. This makes it well suited for electric motors, agricultural machinery, transmissions, pump shafts, automation modules, and general industrial machinery.
Whether mounted as a bearing unit or integrated within a bearing housing, the 6300 2RS C3 provides robust rotational performance in compact form.
Dual rubber contact seals (2RS): Prevent ingress of contaminants, preserve lubrication and extend life.
Increased internal clearance (C3): Offers extra radial play to compensate for thermal expansion and maintain performance in variable conditions.
Deep groove design: Ensures smooth, low-friction operation and supports both radial and moderate axial loads.
Compact geometry: At 10x35x11 mm, it balances size and load capacity for tight assemblies.
High brand quality: Manufactured under SKF standards for precision, durability, and performance consistency.
Low-maintenance operation: Sealing and clearance reduce the need for frequent relubrication or service.

Q: What is the benefit of the “C3” clearance?
A: C3 gives additional internal space, allowing the bearing to accommodate thermal expansion, shaft deflection, or slightly misaligned assemblies without binding.
Q: How effective are 2RS seals in this bearing?
A: The 2RS rubber covers provide excellent protection against dust and moisture. While they slightly increase running resistance, they significantly enhance longevity and reliability.
Q: Can 6300 2RS C3 be used in electric motors?
A: Yes — it’s commonly used in motors, pumps, gearboxes, and automation devices where sealed operation and thermal tolerance are required.
Q: What maximum rotational speed is achievable?
A: The maximum speed depends on lubrication, load, and temperature; sealed bearings typically run slightly slower than open ones, but 6300 2RS C3 still supports high-speed operation within spec.
Q: How fast can I get this bearing?
A: The product is stocked and available for 24h delivery, making it ideal for urgent B2B needs.
