SPINDEL- UND Lagerungstechnik Fraureuth GMBH (SLF) may be tricky for non-Germans to pronounce. However, when it comes to manufacturing spindles and ball bearings, the company is “driven by precision” and dedicated to quality assurance in every department. And that’s a universal language everyone understands.

SLF has been making spindles and spindle bearings since 1993. True to its German heritage, SLF takes pride in product quality and means of production.

In August 2020, SLF acquired STI GmbH (STI) and expanded its product line with complex, customized engineered products and solutions that help strengthen its worldwide sourcing network and solidify its position as a major competitor on the global playing field.

Through an optimal combination of the most modern production technologies and the abilities of their engineers and technicians, SLF continues to fulfill its clients’ strict quality requirements, turning one-time buyers into long-term business relationships.

With clients covering machine construction, drive technology, electric motors and aerospace, the SLF team is continually learning new quality standards. Their DIN EN ISO 9001 certification means they fulfill all criteria and strive to decrease the ecological impact from production. The company believes its task is to produce products in a safe, cost-effective and environmentally friendly manner.

Spindle bearings

SLF understands spindles and spindle bearings and manufactures the bearings and the spindles that use them. That knowledge produces bearings uniquely designed for use in machine tools.

The sales engineers at Alpine are always looking for new bearings to distribute and new companies to work with. Recently they began a relationship with SLF and now stock their machine tool spindle bearings.

Alpine customers have machine shops or manufacturing houses using sophisticated CNC (computer numerical control) machines to run routers, mills, lathes, and grinders. These companies need high-quality machine tool spindle bearings to keep their equipment continually running at peak performance.

SLF produces well-crafted bearings that tolerate acute temperature swings, grueling conditions, extreme environments, and sustained use without lagging.
