Spindle Bearings

High speed spindles require stable bearing operation with minimum friction. Especially in metal processing, the used greases have to provide high thermal stability, withstand high and low operating speeds and be resistant towards water and coolants. To ensure consistent operating conditions of drilling and milling heads, LUBCON offers an assortment of customised lubrication solutions, specially designed for the lubrication of high speed spindle bearings. Our high performance greases feature an optimum base oil viscosity and mechanical thickener stability. Our products meet the bearing requirements in high-precision machine tools, particularly in combination with long-term solutions such as the automatic lubrication unit QuattroMax 30, for maintenance-free high speed spindle lubrication.

Speed factor up to 3 Mio. n • dm

Turmogrease Highspeed L 182

Ester/PAO based, low viscose grease with lithium soap thickener of consistency class 2 for maximum speeds up to 2.5 Mio. n • dm. The base oil viscosity at 40 °C is 18 mm2/s. It is particularly adhesive, resistant towards water and cooling liquids and prevents reliably noise as well as friction and wear. The grease is primarily used in spindle and cylinder roller bearings with an inner ring bore of d = 100 mm.

Turmogrease Highspeed L 252

Ester/PAO based, low viscose grease of consistency class 2-3 with lithium soap thickener for maximum speeds up to 2.2 Mio. n • dm. It is particularly adhesive, resistant towards water and cooling liquids and prevents reliably noise as well as friction and wear. The base oil viscosity at 40 °C is 25 mm2/s. The grease is suitable for life-time lubrication and is successfully utilised by machine tool, spindle and bearing manufacturers.

Speed factor up to 2.2 Mio. n • dm

Sintono N 75

Special PAO/ester lubricant for bearings with an inner ring (mounting diameter of < d = 100 mm). It minimises noise, is resistant towards water and cooling liquids and suitable for spindle bearings with maximum speeds up to 2.2 Mio. n • dm.

Speed factor up to 1.3 Mio. n • dm

Thermoplex 2 TML

Synthetic, long-term lubricant with highly viscose base oil and special EP additives. It is thus suitable for high loads and high operating temperatures. The grease is outstandingly stable at high and low operation speeds and can be used for the lubrication of spindle bearings at speeds up to 1.3 Mio. n • dm.

Speed factor up to 1 Mio. n • dm

Turmogrease Li 802 EP

Long-life grease with lithium soap thickener, combined with special additives for optimum performance in high speed spindles. The bearing grease offers very good lubricating properties and has been especially designed for high loads, temperatures and speeds (up to 1 Mio. n • dm).
