The open configuration accommodates various lubrication methods including oil bath, circulating oil, or grease systems.

The 6426-2RS is a heavy-duty single-row deep groove ball bearing engineered for demanding industrial applications requiring enhanced contamination protection. With a 130 mm bore, 340 mm outer diameter, and 78 mm width, this large-format bearing delivers substantial radial and axial load capacity. Featuring double rubber seals (2RS) on both sides, it provides effective protection against dust, moisture, and particulate contamination while retaining lubricant for extended maintenance intervals. This bearing is commonly specified for heavy electric motors, large pumps, compressors, mining equipment, and industrial gearboxes operating in challenging environments .

The 6404 is a Single Row Deep Groove Ball Bearing designed for dependable performance in a wide spectrum of industrial and mechanical applications. Featuring a deep groove raceway geometry, this bearing efficiently accommodates radial loads as well as moderate axial loads in both directions. With a 20 mm bore, 72 mm outer diameter, and a 19 mm width, it provides a robust and versatile solution for various machinery. Available with different sealing options (open, metal shields, or rubber seals), it is ideal for electric motors, pumps, gearboxes, fans, and other equipment requiring smooth, low‑noise operation and long service life.

The 6404-2RS is a Single Row Deep Groove Ball Bearing with Contact Rubber Seals engineered for reliable performance in demanding industrial environments. With a 20 mm bore, 72 mm outer diameter, and a 19 mm width, it provides a robust and versatile solution for various machinery applications. Featuring the standard deep groove raceway geometry, this bearing efficiently accommodates radial loads as well as moderate axial loads in both directions. Equipped with double rubber seals (2RS) for effective contamination protection and lubricant retention, it is ideally suited for electric motors, pumps, agricultural equipment, and industrial machinery operating in dusty or moist conditions where maintenance access is limited.

Engineered to withstand exceptional radial forces and significant bidirectional thrust loads, the 6415-2RS is a robust, heavy-series deep groove ball bearing equipped with dual synthetic rubber contact seals. Outfitted with premium nitrile rubber lips (2RS), this component provides a highly resilient barrier against abrasive grit, moisture splashback, and external particles while firmly retaining its factory-engineered internal lubrication. Because these reinforced seals maintain uniform contact with the inner ring shoulders, the 6415-2RS ensures structural reliability and optimal runtime in severe working environments. This makes it an indispensable asset for high-stress, large-capacity 75mm shaft applications, including heavy-duty industrial electric motors, mining machinery, and rugged agricultural equipment.

Built to withstand severe radial and axial loads in demanding industrial environments, the 6415 is a heavy-duty single row deep groove ball bearing featuring an open, unsealed design. Unlike shielded or sealed bearings, the open architecture allows for the free, continuous flow of external lubricants directly into the rolling elements. This makes it a critical component for enclosed mechanical systems like large-scale transmissions and oil-bath gearboxes, where operating temperatures and extreme mechanical stress require constant, unhindered lubrication to maintain optimal performance.

Developed to endure extreme mechanical stress and high-impact industrial applications, the 6419-ZZ is a massive, heavy-duty deep groove ball bearing belonging to the robust 6400 series. Integrated with twin pressed-steel shields (ZZ), it forms an effective defense mechanism against airborne grit, slag, and workshop dust while safely encasing the specialized factory grease. Because these structural metal shields do not touch the inner ring, the 6419-ZZ experiences virtually zero added rotational resistance or frictional drag, positioning it as a top-tier choice for massive 95mm shaft systems found in industrial gearboxes, heavy-duty electric motors, and mining equipment.
