NKE's Ball Bearings Offer Low Running Noise
Austrian bearing manufacturer NKE Austria has released a range of single-row deep-groove ball bearings. As one of the most frequently used bearing types worldwide, single-row deep-groove ball bearings are used in an extensive range of applications, which places high demands on their performance and cost-effectiveness. The new NKE POP range of single-row, deep-groove ball bearings offers numerous technical advantages, such as reduced running noise, longer lubricant service life, a low starting torque and outstanding cost-effectiveness.
The ball bearings are subject to stringent, documented quality inspections as well as 100% 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 minimises the bearing's starting torque even at low operating temperatures.The lubricant has a long service life over a wide temperature range - from -50 to 150C.
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 to 60 or 50mm), in open versions 2RS2 version (sealed with two synthetic rubber seals) and 2Z version (sealed with two steel shields) and with clearances CN (standard) and C3.
