FOR SALE NEW BEARINGS 71892-MP-P5-UL FAG Brand FAG Item number 71892-MP-P5-ULFAG Category Single row angular contact ball bearing Weight and dimensions Internal (d) MM 460 External (D) MM 580 Width (B ) MM 56 Weight (kg) 32.2 Product Properties Foca No seal Cage type M - Brass cage Accuracy Accuracy P5 (better than P6) Contact angle 30 degrees Association G - Universal fit Axial internal clearance/preload UL - Universal design for mounting as a pair, the bearing pair has a slight preload in the O and precision and the ability to support combined loads (both radial and axial). 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 consists of the following elements: Inner ring: It is mounted on the machine shaft and rotates with it. Outer ring: 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: Specific characteristic of this type of bearing, which allows it to support axial loads in one direction only, in addition to radial loads. How to obtain the measurements of a bearing The main measurements of the bearing are: Internal diameter (d): Measures the diameter of the central hole of the bearing, which in this case is 460 mm. Outside Diameter (D): Measures the outside diameter of the outer ring, here 580mm. 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 combined radial and axial loads need to be accommodated, often in high-speed machinery. The contact angle between the balls and the races 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 to calculate their correct use Equivalent dynamic load capacity (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. Nominal life (L10): 𝐿 10 = ( 𝐶 𝑃 ) 𝑝 L 10 ​ =( PC ​ ) p Where: 𝐶 C is the dynamic load capacity. 𝑃 P is the equivalent load. 𝑝 p is an exponent that is 3 for ball bearings. Limit speed (n_lim): Indicated in the technical specifications, it is the maximum speed at which the bearing can operate without overheating or wearing prematurely. How an angular contact ball bearing is mounted Cleaning: Make sure all mounting surfaces are clean. Alignment: The shaft and mounting hole must be perfectly aligned. Hot assembly: If necessary, heat the inner ring evenly (not above 120°C) to facilitate insertion onto the shaft. Application of force: Apply uniform and constant force to the ring to be 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: Same as 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. Why it is better to buy new FAG 71892-MP-P5-UL bearings in stock Cost savings: Buying in stock reduces the cost per unit, especially for high quality bearings such as FAG ones. Immediate availability: Having a warehouse with available bearings reduces machine downtime. Maintaining quality: FAG bearings are known for their high quality, and purchasing them in stock ensures the availability of reliable components. Operational Efficiency: Reduces the need for frequent orders and minimizes maintenance delays. Buying FAG 71892-MP-P5-UL bearings in stock is an advantageous strategy for those who need high-precision components and want to avoid downtime in production.
