Technical details and manufacturing context for Vibration Bearings

Definition

Vibration bearings are precision components used in vibration systems to support rotating shafts while allowing controlled movement and damping of oscillatory forces. They are critical for isolating vibration transmission, reducing wear, and maintaining system stability in applications where mechanical oscillations are inherent or intentionally generated, such as vibratory screens, compactors, and shakers. These bearings are engineered to operate under dynamic loads while preserving alignment and preventing resonance buildup that could damage equipment.

Vibration bearings are available in materials including chrome steel, stainless steel, and ceramic, each offering different properties for corrosion resistance, hardness, and weight. The standard metric series covers bore diameters from 20 to 200 mm, outside diameters from 47 to 360 mm, and widths from 14 to 75 mm, per ISO 15. Dynamic load ratings range from 12.5 to 292 kN, static load ratings from 8.0 to 200 kN, and fatigue load limits from 0.5 to 8.0 kN, based on ISO 76 and ISO 281. Limiting speeds for oil lubrication are 3000 to 12000 r/min per ISO 15312. Radial clearance is typically C3 per ISO 5753-1, and tolerance class is P6 per ISO 492. Operating temperature ranges from -40°C to 150°C, with special grease required above 150°C. Vibration acceleration level is ≤50 dB per ISO 15242-1, and noise level is ≤30 dB(A) per ISO 15242-2. Mass ranges from 0.1 to 15 kg.

These parameters serve as directory references and must be verified with the legal manufacturer or supplier for specific models and applications. Standards listed are procurement references and do not imply certification or compliance of any product or supplier. Always confirm model-specific values and standards before selection or installation.

Working Principle

Vibration bearings operate by providing a low-friction interface between moving parts while incorporating design features such as specialized cage designs, damping materials, or clearance adjustments that absorb and dissipate vibrational energy. They maintain alignment under dynamic loads and prevent resonance buildup that could damage equipment. The bearings allow controlled movement and damping of oscillatory forces, isolating vibration transmission and reducing wear in mechanical systems.
