Tool performance is critical to manufacturers, but higher spindle speeds have created the need for a new spindle grease to prevent bearing failure and improve effi ciency. High-speed applications require specialist greases composed of base oils and thickeners, which enable the lubricant to remain in contact with the bearing at all times during operation. For this, Castrol Industrial has developed Castrol Longtime HS 1.5, the fi rst lubricant of its kind with a thickening system based on polymer-type technology. This replaces the traditional soap solution, which can lack stability when in contact with emlusions. Castrol Longtime HS 1.5 is a water- and chemical-resistant grease that offers new levels of reliability, cost savings through longer re-lubrication intervals and lower risk of bearing failure.
