Austrian bearing manufacturer NKE Austria has introduced a range of single row deep groove ball bearings called NKE POP, which offers several technical advantages, such as reduced running noise, longer lubricant service life, and low starting torque. The low running noise is achieved through the use of a new type of lubricant, which also minimises the bearing’s starting torque even at low operating temperatures. The lubricant has a long service life, and can be used from -50 to +150oC.
The bearings feature a pair of newly developed double-lip labyrinth seals, which provide better protection from contamination and improve grease retention in spite of the low friction. The raceways have an enhanced surface finish, which reduces wear and keeps the operating temperature low, while high-grade balls ensure smooth running and reduced noise compared with conventional deep groove ball bearings.
