Description
SKF 7311 BEC86P is a angular contact ball bearing reference, within Bearings. Request a quote for 7311 BEC86P via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SKF angular contact bearing is a component designed to withstand combined radial and axial loads. Its design with offset raceways and contact angle allows it to work with stresses in one main direction. It is used in applications requiring high precision and rigidity, such as machine tool spindles, pumps and gearboxes. At MR Accesorios Industriales we carry this line for the Argentine market, with personalized technical advice.
The designation of these bearings is interpreted from the series and suffixes. For example, 7311 BEC86P corresponds to series 73, which indicates a medium-section angular contact design. The suffix B indicates a 40° contact angle, while EC refers to a high-performance polyamide cage. The number 86 may indicate a special internal clearance and the P a precision tolerance. Each combination of letters and numbers defines specific characteristics that must be verified in the complete part number at the time of inquiry.
These bearings are used in industries such as metalworking, petrochemical, food and power generation. In Argentina, they are common in milling machine and lathe spindles, centrifugal pumps, screw compressors and gearboxes. Their ability to withstand combined loads makes them suitable for equipment where precision and rigidity are critical. They are also used in applications with high speeds and low-friction requirements, such as high-performance electric motors.
To correctly select an angular contact bearing, take into account the predominant load direction, operating speed and environmental conditions. Sealing or shields must be chosen according to contamination and the need for lubricant retention. Internal clearance and preload influence rigidity and service life. During mounting, it is essential to align the rings and apply the preload recommended by the manufacturer. Proper lubrication, whether grease or oil, and temperature control are key for reliable performance.
Regarding equivalences and interchangeability, SKF angular contact bearings can be replaced by products from other brands that follow the same dimensions and standardized designations. However, tolerances and internal clearance may vary between manufacturers, so it is always recommended to verify the complete part number and technical specifications before replacing a bearing. Dimensional interchangeability does not guarantee the same performance in all applications.

Frequently Asked Questions
- What does the BEC suffix mean in an SKF bearing?
- The BEC suffix indicates a 40° contact angle and a high-performance polyamide cage. These characteristics allow it to withstand significant axial loads and high speeds. Always verify the complete part number, as it may include other suffixes that modify clearance or tolerance.
- How do I choose between an angular contact bearing and a deep groove ball bearing?
- The angular contact bearing withstands combined radial and axial loads in one direction, while the deep groove ball bearing is limited to mainly radial loads. If your application has significant axial stresses, the angular contact bearing is the right option. Consult us with your equipment data.
- What should I take into account when mounting an angular contact bearing?
- It is key to respect the orientation of the raceways, apply the correct preload and ensure precise alignment. Lubrication must be as indicated and axial adjustment must be controlled according to the manufacturer. Incorrect mounting can reduce bearing service life. We advise you via WhatsApp.
