C o n t e n t s The right product for any application Screw drive supports Page 4 Main spindles Direct drives Rotary tables Linear technology The right bearing support is a critical factor for the efficiency of a machine tool and the quality of the machined workpieces. For many years, Schaeffler has consistently contributed to the world-leading position of this market sector by means of products under the INA and FAG brands. Through our close partnership, often extending over decades, with the best-known manufacturers of machines, equipment and subsystems in all industrial sectors and our own...

Ready-to-fit compact bearing supports Electromechanical drive concepts for friction and high torsional strength, machine axes can be realized easily these double row axial angular contact and economically using maintenance- ball bearings are in considerable free INA and FAG screw drive support demand worldwide. Seals are already bearings. Based on a deep under- standing of details and systems in relation to this bearing position, a product range was developed that led, through the “ready-to-fit” approach, to demonstrable simplifications and savings in the machine tool as an entire system.

which are axially preloaded in order to compensate thermal expansion. A third row of balls supports the continuously increased levels of unilateral axial load that arise as a result of the tensioning forces. DKLFA bearings are extremely well suited to heavily loaded vertical axes in machine tools. The two flattened areas on the outer ring facilitate designs with extremely low section height. These are also “ready-to-fit”. Our range is rounded out by the high precision, single row FAG universal bearings 7602, 7603 and BSB. These can be used in any combination required for the specific operating...

Attractive solution for milling spindles The new series of high speed axial bearings (BAX) combines high axial load carrying capacity and rigidity with the suitability for high speeds of main spindle bearings. Bearings of this series are dimensionally compatible with spindle bearings of series 70 and have a contact angle of 30° (optionally 40°). When used in combination with modern, high speed cylindrical roller bearings of types N10 and NN30 in particular, it is possible to realize highly robust spindles with high axial and radial load carrying capacity and suitability for very high speeds....

... through to the system solution, matching customer requirements The I-D-E-A-S concept: Keeping the customer in mind Literally no other manufacturer can supply all the components for standardized or customer-specific system solutions for automation in manufacturing. Our systems specialists have access to one of the world’s most-comprehensive ranges of linear and rotary rolling bearing products. They provide a large variety of mechanical and mechatronic components as well as Schaeffler’s entire range of replacement part and aftersales services. Three options for system solutions Manufacturing...

The perfect drive system for any application they develop an extraordinary power density. These almost wear-free drives have a wide range of positive points including: • High speed as well as speed variance • Very good dynamic characteristics and rigidity • High final speeds • High acceleration and braking capacity • Very high positioning and repeat accuracy • Minimal power loss through heat dissipation In appropriate applications, IDAM direct drives have major advantages, Thread whirling machine with torque motor (type RI) in terms of energy consumption while achieving very high performance,...
