Zkl Four Point Contact Ball Bearings

ZKL Four-Point Contact Ball Bearing, Inner Dia 120 mm, Outer Dia 260 mm, Width 55 mm, QJ324N2MA Four point contact Bearing are single row, non self-retaining radial ball Bearing. They are similar in their structure to single row radial angular contact ball Bearing; the raceways on the inner rings are, however, designed such that they can support axial loads in both directions

A ZKL Four-Point Contact Ball Bearing Inner Dia 220 mm Outer Dia 340 mm Width 56 mm, QJ1044N2MA C3 is a specialized type of rolling-element bearing designed to support both radial and axial loads by providing contact between the balls and the raceways at four points rather than two points as in typical radial ball bearings. This unique design allows for greater axial load capacity and axial stiffness while still maintaining radial load support. Four-point contact ball bearings are commonly used in applications where both radial and axial loads are present, such as in slewing rings, turntables, and robotics. Here are the key features and components of a four-point contact ball bearing: Inner Ring: The inner ring of a four-point contact ball bearing is typically mounted onto a shaft and provides a mating surface for the balls. It contains a raceway or groove along its circumference, which guides the balls and allows them to roll smoothly. Outer Ring: The outer ring of a four-point contact ball bearing is mounted within a housing or support structure and provides support and alignment for the bearing assembly. It contains a complementary raceway or groove to the inner ring to guide the balls and facilitate smooth rotation. Ball Bearings: Four-point contact ball bearings contain spherical ball bearings arranged in a circular raceway between the inner and outer rings. These ball bearings transmit both radial and axial loads by making contact with the raceways at four points. The four-point contact design allows for greater axial load capacity and axial stiffness compared to typical radial ball bearings. Cage or Separator: The cage or separator holds the ball bearings in place within the bearing assembly, ensuring proper spacing and alignment between the balls. It prevents the balls from coming into contact with each other, reducing friction and wear. The cage may be made of steel, brass, or other materials, depending on the application and operating conditions. Raceways: The raceways are grooves or channels machined into the inner and outer rings of the four-point contact ball bearing. These raceways provide a smooth and precise path for the balls to roll along, transmitting radial and axial loads from one ring to the other. Four-Point Contact Design: The four-point contact design of the bearing allows for contact between the balls and the raceways at four points rather than two points as in typical radial ball bearings. This design distributes the load more evenly and efficiently, resulting in greater axial load capacity and axial stiffness. Axial Load Capacity: Four-point contact ball bearings are optimized for handling axial loads in both directions, making them ideal for applications where axial loading is significant. The four-point contact design ensures that the bearing can withstand higher axial loads without sacrificing radial load support. Radial Load Capacity: While primarily designed to support axial loads, four-point contact ball bearings can also accommodate radial loads to a certain extent. However, their radial load-carrying capacity is lower compared to dedicated radial ball bearings. Overall, four-point contact ball bearings offer a unique combination of radial and axial load support, making them suitable for a wide range of applications where both types of loads are present. By providing efficient load distribution and high stiffness, four-point contact ball bearings contribute to the reliability and performance of machinery and equipment in various industries.
