In the framework of the company´s AIP added-value programme, NSK recently helped an automotive component manufacturer to optimise the drive systems in its machining centres, a move that led to six times greater service life and annual savings of approximately €266,000.
High temperatures, coolants, strong forces and high precision:
machine tools make exceptional demands on ball screws.
At a factory in Spain producing automotive brake systems for the global marketplace, some 117 ball screws facilitate linear motion and tool table/changer positioning in a large number of CNC machining centres. However, because of stringent requirements and tough environmental conditions, the ball screws have an average service life of only six months. As a consequence, unscheduled downtimes were causing considerable additional costs to be incurred.
The supplier asked NSK for its expert advice to help to reduce the downtime frequency. In these situations, NSK offers support to customers in the framework of its proven AIP programme. A team of company specialists duly investigated the raceways and lubrication conditions in three faulty linear drives in order to determine failure causes. The result: a combination of high loads, penetrating cutting fluids and high ambient temperatures was responsible for the short lifespan.
To counter these issues, NSK recommended using ball screws that have been specially developed for high speeds and loads. This product range features a customer-specific nut that is tailored exactly to the application and provides greater axial stiffness, not just of the ball screw, but the entire powertrain, thus increasing machine precision. Moreover, as preload is spread over several balls, service life is increased considerably.
As recommended by NSK, the ball screws were equipped with the company´s proprietary X1 high-performance seals. These seals prevent any cutting fluid from penetrating the linear system and stop the ball screw lubricant from contaminating the machining centre’s cutting fluid or coolant. The X1 seal also has excellent grease-retention capabilities.
Optimal lubrication of the ball screw in tough operating conditions is assured by using the K1 lubrication unit, which enables the lubricant’s useful life to be considerably prolonged, again contributing to lower maintenance costs.
On a trial basis, two of the new NSK ball screws were fitted to the machining centres in Spain. The results were highly successful: ball screw lifespan increased by a factor of six. Furthermore, since installation, there have been no more failures.
The automotive supplier can now benefit from lower spare part costs and, above all, from significantly less
production downtime: total yearly cost savings of approximately €266,000 have been achieved.

from penetrating the ball screw.
IVT Expo 2019 to showcase innovative Altra powertrain solutions
From February 13th – 14th, visitors to the Industrial Vehicle Technology (IVT) Expo will be able to meet with leading brands of the Altra Industrial Motion Corp., to see first-hand a selection of high-performance power transmission components for industrial and off-highway vehicles. Taking place in Hall 11.1 of Köln Messe in Cologne, Germany, attendees will be able to discuss their specific powertrain requirements with Altra Industrial Motion Corp. representatives on Stand 2068.
Altra combines leading power transmission brands under one umbrella, providing original equipment manufacturers (OEMs) and vehicle manufacturers with access to standard and custom solutions including brakes, clutches, couplings and linear actuators. Able to support diesel, hybrid or electric powertrains, Altra manufactures all products in-house, ensuring consistent high quality plus plug-and-play integration between its products for reduced assembly times. The business even offers OEMs drivetrain torsional vibration analysis to prove performance for an application. Supported industries include agriculture, forestry, commercial and construction vehicles.
Altra’s breadth of expertise is reflected in the products on the stand. Stromag, a provider of industrial clutches, couplings and brakes since 1932, will be displaying a number of its innovative designs. First up is the KMB hydraulically released, spring applied brake, which can be specified in dry or wet configuration for lower maintenance requirements. Ideal for mobile applications, the range can be specified in braking torque ranges from 50 Nm to 50,000 Nm and above. Stromag also offers its customers the benefit of plug-and-play designs, either as part of finished assemblies or sub-assemblies for quick integration into axles or gearboxes. The KMB is a long-standing favourite of end users in the construction sector.
Along with brakes, Stromag is a leading manufacturer of clutches such as the MWU range. Favoured in agricultural machinery and municipal vehicles, the MWU features a single disc, backlash-free, electromagnetic design. Its compact dimensions, zero backlash characteristics and low power consumption makes this clutch ideal for hybrid and other powertrains. Different coil voltages and hub bore dimensions mean this clutch can be tailored to suit a new design or modified to be integrated in an existing vehicle drivetrain with increased ease.
Together with Stromag on the stand will be Warner Electric, a global leader in the development of electromagnetic clutches and brakes since 1927. Among the products on show will be fan drive clutches, which are engaged only when required. This feature results in improved fuel economy, quicker engine warm up and increased engine performance. Providing high torque in a small envelope, fan clutches can be specified in electromagnetic on/off and hydraulically actuated, multi-disc designs, with custom solutions to meet specific customer requirements.
Air conditioning compressor and fan clutches, well suited for busses, trucks and off highway equipment will also be present. Warner AC compressor and fan clutches offer dynamic engagement. Furthermore, customised designs are available for plug-and-play integration.
Regenerative braking is a technology that is enhancing the economy of all vehicles. Warner Electric’s PK (Pancake) brakes offers a cost competitive, highly efficient solution in this regard. These dry electromagnetic brakes work in conjunction with the AC motor and improve overall vehicle efficiency. Featuring a one-piece design for easy assembly, the PK brake combines low power consumption, increased battery life and reduced maintenance requirements. A compact footprint also ensures that the PK can be inserted into drive trains that offer minimal space, which in terms of the packaging typical of hybrid and electric vehicles, is a distinct advantage.
