The BSB035072-T (sometimes written as BSD3572C) is a specific type of ball screw support bearing, often categorized as a thrust angular contact ball bearing. These bearings are designed to support the axial load and provide precise linear motion in ball screw applications, typically found in machinery and equipment where high precision and minimal backlash are required.
Size: The bearing has a standardized size of 35mm (inner diameter), 72mm (outer diameter), and a height of 15mm. These measurements are critical as they must match the corresponding dimensions of the ball screw shaft and housing for proper installation.
Angular Contact Ball Bearings: This type of bearing uses angular contact ball bearings to support axial (thrust) loads. Angular contact bearings are designed to handle both axial and radial loads, but in this application, they primarily deal with axial loads.
Thrust Bearing: It is specifically designed to handle thrust or axial loads, which means it's optimized to support loads applied parallel to the shaft's axis. This is essential in ball screw applications where precise linear motion is required.
Ball Screw Support: These bearings are commonly used in conjunction with ball screws. Ball screws are a type of linear motion mechanism that uses recirculating ball bearings to convert rotary motion into linear motion and vice versa. The ball screw support bearing ensures smooth and precise motion along the shaft.
High Precision: Ball screw support bearings are engineered for high precision, which is crucial in applications where accuracy and repeatability are essential.
Minimal Backlash: These bearings are designed to minimize backlash or play in the system. Backlash is the amount of clearance or "looseness" in the system and can affect the precision of the linear motion. The BSB035072-T is designed to reduce this effect.
Lubrication: Proper lubrication is essential to ensure the smooth operation and longevity of the bearing. The type of lubrication and maintenance requirements may vary based on the manufacturer's specifications.
Mounting: Proper mounting is crucial to ensure the bearing's effectiveness and longevity. Bearings like the BSB035072-T should be properly preloaded and aligned to meet the application's requirements.
Applications: These bearings are commonly used in various industrial machinery and automation equipment, such as CNC machines, robotics, and other applications where precise linear motion is essential.
When selecting ball screw support bearings like the BSB035072-T, it's important to consider factors such as the load requirements, speed, precision, and any environmental conditions that may affect the bearing's performance. Additionally, manufacturers often provide detailed technical specifications and guidelines for their products to ensure proper selection and installation.
