Ligero 627 7x22x7mm Plastic Miniature Deep Groove Ball Bearing

627 Plastic Deep Groove Ball Bearing – The Maintenance-Free, Lightweight Solution for Wet and Sensitive Environments

El 627 plastic bearing utilizes advanced engineering polymer materials that solve four fundamental industrial problems: corrosión, sanitary contamination from lubricants, electrical conductivity, and weight. Fabricated from premium acetal (polyoxymethylene, POM) resin for the raceways, with precision glass balls and a PA66 glass-fiber reinforced cage, this bearing operates effectively under conditions that would rapidly destroy an all-metal bearing

Key Advantages

• No Lubrication Required
  POM (acetal) is inherently self-lubricating; it doesn’t need external oil or grease to reduce friction between the rolling elements and raceways. The bearing runs completely dry while maintaining a low coefficient of friction and smooth rotation.No risk of grease contamination of food products, medical instruments, or chemical processes.

• Extremely Lightweight
  El 627 plastic bearing weighs only about 2.5 a 4 grams — roughly 30 a 40 percent of the weight of a standard 627 steel bearing.Reduced overall equipment weight and lower power consumption.

• Non-Magnetic & Electrically Insulating
  Plastic bearings are completely non-magnetic and electrically insulating.Because the 627 plastic bearing uses plastic rings and glass balls, it creates no magnetic interference and provides complete electrical isolation between the shaft and housing.

• Bajo nivel de ruido & Low Vibration Operation
  El 627 plastic bearing’s acetal raceways dampen vibration, absorb impact energy, and drastically reduce operating noise compared to steel equivalents.This makes it particularly attractive in consumer electronics, office machinery, dispositivos médicos, and any application where quiet operation directly affects user comfort.

• Food-Contact Safety
  For food processing and pharmaceutical applications, lubricant contamination is a critical hazard. El 627 plastic bearing can be manufactured with FDA-approved materials and operates completely dry, eliminating the risk of grease contamination of food or drug products.
