This bearing is particularly suitable for high-performance machinery, such as machine tools and precision equipment. How an angular contact ball bearing is made An angular contact ball bearing is made up of the following elements: Inner ring: It is mounted on the machine shaft and rotates with it. Outer ring: It is housed in the support and generally remains fixed. Balls: These are the rolling elements that allow movement between the inner and outer rings, reducing friction. Cage: Keeps the balls equidistant and guides their movement. Contact angle: A specific characteristic of this type of bearing, which allows it to support axial loads in only one direction, in addition to radial loads. How to calculate the dimensions of a bearing The main bearing dimensions are: Inner diameter (d): Measures the diameter of the central bore of the bearing, which in this case is 460 mm. Outer diameter (D): Measures the outside diameter of the outer ring, here 580 mm. Width (B): Measures the overall width of the bearing, equal to 56 mm. These dimensions can be obtained using precision measuring instruments such as calipers or micrometers, or by consulting the technical data sheets provided by the manufacturer. How to use an angular contact ball bearing This type of bearing is used in applications where it is necessary to support combined radial and axial loads, often in high-speed machinery. The contact angle between the balls and the raceways determines the ability to support axial loads. It is often mounted in pairs or in more complex configurations to handle axial loads in both directions. Formulas for calculating their correct use Equivalent dynamic load rating (P): 𝑃 = 𝑋 ⋅ 𝐹 𝑟 + 𝑌 ⋅ 𝐹 𝑎 P=X⋅F r ​ +Y⋅F a ​ Where: 𝐹 𝑟 F r ​ is the radial load. 𝐹 𝑎 F a ​ is the axial load. 𝑋 X and 𝑌 Y are bearing-specific factors provided by the manufacturer. Rating life (L10): 𝐿 10 = ( 𝐶 𝑃 ) 𝑝 L 10 ​ =( PC ​ ) p Where: 𝐶 C is the dynamic load rating. 𝑃 P is the equivalent load. 𝑝 p is an exponent equal to 3 for ball bearings. Limiting speed (n_lim): Indicated in the technical specifications, it is the maximum speed at which the bearing can operate without overheating or prematurely wearing. How to mount an angular contact ball bearing Cleaning: Make sure all mounting surfaces are clean. Alignment: The shaft and mounting hole must be perfectly aligned. Hot mounting: If necessary, heat the inner ring uniformly (not exceeding 120°C) to facilitate its insertion onto the shaft. Force Application: Apply a uniform, consistent force to the ring being mounted, using appropriate tools to avoid damage. Lubrication: Use an appropriate lubricant to ensure smooth operation and prevent wear. Types of Angular Contact Ball Bearings Single-row ball bearings: Such as the FAG 71892-MP-P5-UL, for axial loads in one direction. Double-row ball bearings: For axial loads in both directions and radial loads. High-precision bearings: Used in applications such as machine tool spindles.
