Deep groove ball bearing SKF 6305-2RS2/C3HHT, Outer diameter: 62 mm | Width: 17 mm | Inner diameter: 25 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.

Designed for high-temperature applications, sealed, capable of withstanding both radial and axial loads while ensuring easy installation, this SKF deep groove ball bearing is engineered to deliver excellent performance. It is ideal for applications in hot environments where reliability, speed, and protection against contaminants are essential.

Features:
This single-row deep groove ball bearing is heat-treated and factory-lubricated with a special high-temperature grease. Its FKM fluorocarbon rubber lip seals provide an effective barrier against dust, water, and chemical contaminants, ensuring enhanced protection for the rolling elements. Thanks to increased internal clearance (C3) and its heat treatment, it better tolerates thermal expansion and is suited for high speeds, making it an ideal solution for high-speed applications requiring good heat dissipation. The sheet steel cage reinforces its resistance to constant loads and allows it to handle shocks as well as sudden increases in force. Finally, it stands out for its ability to withstand heavy radial loads and moderate axial loads in both directions.

Maintenance:
This SKF deep groove ball bearing is equipped with two rubber seals, which reduces maintenance requirements. The sealed design keeps the grease inside the bearing, thereby extending its service life and avoiding frequent servicing. However, it is recommended to occasionally monitor:
- Temperature;
- Seal integrity;
- Vibrations;
- Alignment;
- Absence of abnormal noises.
It is recommended to increase the frequency of inspections as the bearing approaches the end of its rated service life.

Sealing:
Double-lip fluorocarbon rubber (FKM) contact seals provide effective protection against dust, water, and various contaminants (smoke, fibers, moisture, etc.), while keeping the high-temperature lubricant inside the bearing. This material, a blend of synthetic rubber and elastomer, is distinguished by its exceptional resistance to oils, greases, hydrocarbons, diluted acids, and high temperatures up to 200 °C. Thanks to this sealing, the bearing’s service life is extended.
