61902ce bearing

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

The 61902CE bearing is a type of deep groove ball bearing with specific features and applications. Here's a detailed introduction to the 61902CE bearing:

1. General Description:

• The 61902CE bearing is a single-row deep groove ball bearing with a strong universality, low friction, and is optimized to reduce noise and vibration, thereby increasing rotational speed. It is capable of withstanding both radial and bidirectional axial loads with ease of installation and minimal maintenance requirements compared to many other bearing types .

2. Technical Specifications:

• Dynamic Load Rating: 4.36 kN

• Static Load Rating: 2.24 kN

• Reference Speed: 56,000 r/min

• Limit Speed: 28,000 r/min

• Grease Lubrication: Yes

• Seal Type: Non-contact seals on both sides to prevent grease leakage and contamination .

3. Design and Construction:

• The 61902CE bearing features a cylindrical bore and a steel cage. The bearing material is made of bearing steel, and it does not have a coating. The radial play is CN, which is a standard designation for radial clearance in bearings .

4. Applications:

• This bearing is used in various applications where high speeds and precision are required. It is suitable for manufacturing plants, machinery repair shops, and other industrial settings where reliability and durability are crucial .

5. Material and Performance:

• The 61902CE bearing is available in full ceramic Si3N4 (Silicon Nitride) material, which offers excellent performance in high-temperature and high-speed applications. The ceramic balls provide low friction and excellent wear resistance, making it suitable for applications where conventional steel bearings may fail due to high temperatures or corrosion  and .

6. Advantages:

• Corrosion Resistance: The ceramic material is inherently resistant to corrosion, making it suitable for use in environments where conventional steel bearings would corrode.

• High-Temperature Tolerance: Ceramic bearings can operate at higher temperatures compared to steel bearings, which is beneficial in applications with heat generation.

• Self-Lubricating: Due to the low friction coefficient and smooth surface, ceramic bearings have good self-lubricating properties, which can be advantageous in environments where lubrication is difficult or impossible.

• Magnetic Resistance: Ceramic materials are non-magnetic, which helps in applications where magnetic interference is a concern .

7. Packaging and Supply:

• The 61902CE bearing is supplied in CLUNT packaging, ensuring safe and secure delivery. The supplier is capable of providing a large quantity of bearings per week, indicating a strong supply chain and production capacity .

In summary, the 61902CE bearing is a high-performance deep groove ball bearing designed for applications requiring high speeds, low friction, and resistance to corrosion and high temperatures. Its ceramic construction offers significant advantages over traditional steel bearings in certain environments.
