Alfred Jäger, more than 40 years of German expertise in high-frequency spindles

TLDR: Alfred Jäger GmbH SF-Elektromaschinenbau (Ober-Mörlen, Germany, more than 40 years of experience in spindle and application technology) offers a complete programme of high-frequency spindles together with the associated control and power supply systems, for very high precision machining work.

Based in Ober-Mörlen in Germany, Alfred Jäger GmbH SF-Elektromaschinenbau draws on more than 40 years of experience in spindle and application technology, with solid know-how and recognised reliability. A dedicated development and production team ensures that the exceptionally high performance criteria of the brand are met. Development, design and production, all carried out in Germany, guarantee the highest quality, with representatives worldwide providing optimal, customer-focused advice. The Jäger high-frequency spindle programme, combined with the necessary control and power supply systems, offers complete solutions for high-precision machining work.

A range of high-frequency spindles with hybrid bearings, up to 60,000 rpm

TLDR: Jäger spindles, such as the 42-2 W38 FS series or the Z33/Z42/Z62 range, use hybrid or steel ball bearings with lifetime lubrication, for rotation speeds of up to 60,000 rpm, with runout accuracy below 1 micron measured in the shaft taper.

Jäger precision spindles, such as the 42-2 W38 FS series, offer runout accuracy below 1 micron measured in the shaft taper, ensuring low-vibration operation and a long service life on CNC machines. These spindles, available with hybrid or steel ball double bearings combined with lifetime lubrication, cover rotation speeds of up to 60,000 rpm for housing diameters typically of 42 mm, with rated power from 0.3 to 2.5 kW depending on the configuration (S1-100%, S6-60%, or a 5-second peak). Tool changing can be manual (6D, 8/5° or 875 collet types) or by direct pneumatic change on the most automated models, with a typical clamping range up to 6 mm. A Hall-effect speed sensor and PTC motor protection are fitted on most configurations, with ESD protection on certain models.
