SKF 22205 EK 25x52x18 - Spherical Roller Bearing (Self-Aligning)

Applications & Use Cases

The SKF 22205 EK is a robust spherical roller bearing engineered for demanding industrial systems. Its self-aligning capability allows it to accept shaft misalignment and deflection with minimal friction increase. This makes it particularly suitable for heavy machinery, gearboxes, motors, gear drives, conveyors, and readiness for integration with bearing housings or bearing units.

The EK suffix indicates a tapered bore (commonly 1:12), which simplifies mounting using taper adapter sleeves — a preferred mechanism in industrial applications requiring precise installation and reliable performance.

Key Advantages & Characteristics

• Self-aligning design: The dual-row barrel rollers and spherical outer ring geometry permit angular misalignment without undue stresses on rollers or races.

• High radial and axial load capacity: Handles strong radial loads and axial forces in both directions thanks to its dual-row configuration.

• Tapered bore (EK): Enables secure and precise mounting with adapter sleeves, facilitating adjustment and axial positioning.

• Durability and stability: Made from high-grade bearing steel with precision manufacturing to withstand cyclic loads, vibrations, and thermal changes.

• Low friction and thermal stability: Engineering of rollers and guiding rings ensures minimal frictional heating under load.

• Flexible arrangement: Compatible with multiple housing styles, lubrication systems, and industrial environments.

Technical Data

FAQ

Q: What does the “EK” designation mean?
The “EK” suffix denotes a tapered bore (usually 1:12), enabling use of adapter sleeves for precise mounting.

Q: Can the 22205 EK bear axial loads?
Yes — by virtue of its dual-row design, it supports both radial and axial loads (in both directions) under proper layout.

Q: How much misalignment can it tolerate?
Because of its spherical design, it tolerates a modest angular misalignment between shaft and housing without loss of performance.

Q: What types of industrial systems typically use this bearing?
Used in heavy-duty gearboxes, motors, rolling mills, conveyors, industrial drives, and any system requiring reliable load support and alignment tolerance.

Q: How is it mounted?
Use of taper adapter sleeves or appropriate locating devices is recommended to ensure correct axial positioning and preload.
