The new NKE deep groove ball bearings are subject to stringent, documented quality inspections as well as 100 percent noise testing, which helps ensure their high precision and quiet operation. The low running noise is achieved through the use of a new type of lubricant, which also minimizes the bearing’s starting torque even at low operating temperatures. The lubricant has a long service life over a wide temperature range – from minus 50 to plus 150 degrees Celsius. The bearings feature a pair of newly developed double-lipped labyrinth seals, which provide better protection from contamination and improve grease retention in spite of the low friction. The bearings’ raceways have an enhanced surface finish, which reduces wear and keeps the operating temperature low. Their high-grade balls ensure smooth running and reduced noise compared to conventional deep groove ball bearings.
The new POP range of single row deep groove ball bearings is available from stock in the size ranges 6000 to 6012, 6200 to 6212 and 6300 to 6310 (with bore diameters from 10 mm to 60 mm or 50 mm), in open version, 2RS2 version (sealed with two synthetic rubber seals) and 2Z version (sealed with two steel shields) and with clearances CN (standard) and C3. Other versions and sizes are available on request.
