NKE Austria has introduced its range of single row deep groove ball bearings. As one of the most commonly used type of bearing, NKE's single-row deep groove ball bearings excel with their reduced running noise, longer relubrication intervals and a low starting torque, making them a highly cost-effective choice.
The deep groove 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 -50ºC to +150ºC. 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 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 10mm to 60mm or 50mm, 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.
