Features:
 
Prioritizing quiet operation and user comfort, these flanged miniature bearings are designed for applications where noise reduction is a key requirement. They are extensively used in office equipment, household appliances, medical devices near patients, and other noise-sensitive environments.
 
✅ Flange-Enhanced Acoustic Dampening
The flange design adds mass and rigidity at the mounting point, helping to absorb vibrations that are a primary source of audible noise in rotating assemblies.
✅ Optimized for Low Noise Emission
Through precision manufacturing and a carefully selected cage design, these bearings operate with exceptionally low acoustic signatures, contributing to the quiet performance of devices like MRI machines, computer cooling fans, and document printers.
✅ Smooth Raceway Finishing
A specialized finishing process on the raceways and balls minimizes surface imperfections that can cause vibration and noise, ensuring whisper-quiet operation in luxury appliances and audio equipment.
✅ Maintenance-Free Longevity
Pre-lubricated with a long-life grease and effectively sealed, these bearings require no maintenance over the entire life of the product, ensuring consistent quiet performance in embedded applications like HVAC actuators and powered furniture.
 
By minimizing auditory disturbance, these bearings enhance the user experience in a wide array of consumer and professional products.
