Rulment cu role sferice SKF 22314 EK/VA405

Rulmenții cu bile pe role joacă un rol cheie în buna funcționare a instalațiilor supuse unor solicitări mecanice intense. Designul lor robust asigură o performanță fiabilă și continuă, chiar și atunci când condițiile de funcționare sunt instabile sau dificile.

This SKF spherical roller bearing is a high-performance solution designed for industrial applications subject to vibration. It offers exceptional reliability thanks to its self-aligning capability and its design optimized to withstand heavy loads.

Features:
This SKF bearing features two symmetrical rows of rollers, allowing it to compensate for misalignment and shaft deflection. Its advanced E-design, with hardened sheet steel cages, optimizes load distribution and reduces inertia, thereby enabling high rotational speeds. The tapered bore facilitates precise mounting, with or without a locking collar, for optimal adjustment of the internal clearance. This type of self-aligning ball bearing features an annular groove and lubrication holes on the outer ring, simplifying relubrication. The C4 internal radial clearance, standard on VA405 versions, offers better tolerance to thermal expansion and high speeds, ensuring smooth rotation even under load.

Maintenance:
This bearing requires special attention regarding maintenance due to its open design. Regular relubrication is crucial to maintain its performance and extend its service life. The annular groove and lubrication holes facilitate the even application of lubricant. It is essential to use a high-quality grease suitable for the specific loads and operating conditions. The maximum operating temperature of the bearing itself is high (approximately 200 °C), but it is limited by the chosen lubricant.

Sealing:
This bearing model is of the open type, meaning it has no built-in seals. This characteristic makes it susceptible to external contaminants such as dust, particles, and moisture. However, the absence of seals minimizes internal friction, contributing to reduced energy consumption and higher rotational speeds.

Brand Information:
Founded in 1907 in Sweden, SKF is a global leader in rotating technology. With a presence in over 130 countries and thousands of distributors, SKF is dedicated to reducing friction and driving sustainable innovation. The brand invests significantly in R&D to develop higher-performance, energy-efficient solutions for more than 40 industrial sectors, from automotive to aerospace.

Key Benefits:
- High load capacity: withstands heavy radial and axial loads in both directions.
- Self-alignment: effectively compensates for misalignment and shaft deflection.
- Increased robustness: designed to withstand intense vibrations and high centrifugal forces (VA405).
- High speed: optimized design (E-type, C4 clearance, sheet metal cage) for high rotational speeds.
- Wear resistance: hardened sheet metal cage for improved durability, especially in the presence of contaminants.
- Easy maintenance: integrated lubrication system for efficient relubrication.
- Precise mounting: tapered bore for a tight fit and tight tolerance control

Applications:
This type of bearing is particularly well-suited for applications subjected to severe conditions, including heavy loads and significant vibrations. It excels in equipment such as road rollers, industrial saw frames, vibrating screens, and other heavy industrial machinery. Its robust design makes it ideal for environments where loads, speeds, accelerations, and centrifugal forces are very high, ensuring reliable performance where a standard rigid ball bearing might not suffice.
