Deep groove ball bearing SKF 6306-RS1/C3, Outer diameter: 72 mm | Width: 19 mm | Inner diameter: 30 mm

Ball bearings are essential mechanical components that reduce friction and support various loads in a wide range of industrial applications. Among them, deep groove ball bearings stand out for their versatility, ability to operate at high speeds, and low maintenance requirements.

This SKF-brand deep groove ball bearing is designed to deliver optimal performance in demanding environments. Thanks to its increased internal radial clearance (C3) and rubber seal (RS1), it ensures high resistance to friction while allowing for efficient heat dissipation. Ideal for industrial applications requiring high speeds and increased durability.

Features:
This deep-groove ball bearing is manufactured with a sturdy sheet steel cage, ensuring even ball distribution and excellent resistance to constant loads. Its C3 internal radial clearance reduces friction while facilitating high-speed operation. The rubber seal on one side provides reliable lateral protection against water and dust, while reducing the frequency of maintenance.

Key Features:
- C3 radial clearance for guaranteed high-speed efficiency.
- Effective protection against external contaminants thanks to the rubber seal.
- Excellent resistance to radial loads and good tolerance for axial loads.
- Increased durability in high-temperature environments.

Applications:
This bearing is ideal for use in electric motors, pumps, fans, and machine tools operating at high speeds. Thanks to its increased internal radial clearance, it is perfectly suited for environments where thermal expansion and heat dissipation are critical factors. Its robustness also makes it suitable for industrial applications where reliability and longevity are essential.
Its single-sided seal typically requires mounting on a housing, where the unprotected side is in contact with oil (crankshaft, transfer case, gearbox, etc.).

Maintenance:
This type of SKF bearing, with a rubber seal, requires little maintenance thanks to its excellent lubricant retention. The raceway is protected against dust and moisture, thereby reducing the frequency of maintenance interventions. However, like all bearings, their service life is limited, so it is necessary to verify their condition by monitoring temperature and ensuring there is no vibration.

Sealing:
The rubber seal (RS1) on one side of the bearing provides effective protection against water and dust, ensuring reliable sealing against contaminants (fine dust, fumes, water, splashes, etc.). However, the other side of the bearing remains open, providing direct access for certain applications where ventilation or oil lubrication is required.
