Foreword

In many applications (for example in the handling and automation sector), small loads must be moved reliably, quickly and accurately. Furthermore, there is often very little space available to accommodate handling systems.For these applications, we have developed our new compact linear actuators of series MKUVS32.

High load capacity, rigid,cost-effective, precise

The new compact linear actuators are standard, ready-to-fit compact actuators with high rigidity and load carrying capacity.They can support forces from all directions (apart from the direction of motion) and moments about all axes.They contain a precise guidance system, a rigid support rail and a precise drive unit with a high precision spindle.

Accessories The comprehensive standard range can be further optimised by means of a range of accessories precisely matched to various application requirements.

Compact linear actuatorwith ball screw drive

Features Compact linear actuators MKUVS32 comprise a support rail,one or two carriages guided in the support rail and a high precision ball screw drive.The carriage is guided in the support rail by means of two or four linear recirculating ball bearing units KUVS32.Due to their wide base and small height, the linear actuators ofthe SLIVER series allow high performance within compact dimensions.These linear actuators allow accelerations of up to 30 m/s2

and travel speeds of up to 1 m/s.The maximum stroke length is 1022 mm.

Applications The compact linear actuators can support forces from all directions and moments about all axes. They offer high load carrying capacity with high precision.They are highly suitable for applications in:■ assembly systems, for example in semiconductor production■ inspection and measurement systems■ medical equipment■ electronic component manufacture■ handling systems■ automatic welding equipment.

Sealing In order to protect the linear guidance system and drive spindle against contamination, linear actuators MKUVS32 can be supplied with strip covers made from alloy sheet steel (suffix ADA). In this design, the carriages are produced with a covering strip guide on both end faces. As a result, the stroke length is reduced.



Support rail The support rail is a composite rail, Figure 1. It comprises a profiled carrier rail made from anodised aluminium and a guideway for the linear recirculating ball bearing units. The integral slots allow simple mounting of end position and zero point sensors.The maximum length of the support rail is 1100 mm.

Carriage The carriage consists of an anodised aluminium saddle plate,the spindle nut and two or four linear recirculating ball bearing units KUVS32, Figure 2. It is driven by means of the ball screw drive.The linear guidance system and the spindle nut can be relubricated via two lubrication nipples on each of the longitudinal faces.The carriage has an integrated magnet for Hall sensors.

Design andsafety guidelines

Maximum travel speedof carriage

Screw drives must not be allowed to run in the critical speed range. This is dependent on the spindle length, spindle diameterand mounting arrangement. The travel speed of the carriage is dependent on the spindle pitch and the profiled rail length L2, Figure 5.

Lubrication The guidance systems and the ball screw drive in the compact linear actuators are supplied with an initial grease filling of a high quality lithium complex soap grease KP2P–35 to DIN 51 825 and must be relubricated during operation.

Lubrication of the guidance systems The guidance systems and the ball screw drive (the contact zones between the rolling elements and raceways) must be lubricated.The relubrication intervals are essentially dependent on the carriage travel speed, the load, the operating temperature, the stroke length and the environmental conditions. The cleaner the environment,the lower the lubricant consumption.The carriage must be moved during the lubrication process.The carriage must be moved slowly during relubricationof the spindle nut (Figure 6 � or �).Relubrication should be carried out using a lithium or lithium complex soap grease with a mineral oil or poly-alpha-olefin base.If different greases are used, their miscibility and compatibilitymust be checked first.The viscosity of the base oil should be in the range ISO-VG 68to ISO-VG 100. The consistency corresponds to NLGI class 2.The grease must have particular anti-wear characteristics at loads of C/P � 8. This is indicated by the letter P in the DIN designation,for example: DIN 51 825–KP2P–35.Relubrication should be carried out wherever possible with several partial quantities at various times instead of the complete quantity at the time of the relubrication interval.Relubrication is carried out via three lubrication nipples onthe longitudinal faces of the carriage.Lubricant must be supplied to the guidance system from the leftand right (lubrication points � and �) and can be supplied tothe ball screw drive from the left or right (lubrication point � or �).

For relubrication, a conical or needlepoint grease nozzle must be used to press the lubricant into the lubrication nipple.

�, � Lubrication points for the spindle nut

The threads of the lubrication nipples can also be used for connection to a central lubrication system.The grease gun, lubrication nipple, vicinity of the lubrication nipple and grease must be clean.Lubrication should always be carried out with the linear actuator warm from operation.Move the carriage during lubrication.Move the carriage slowly during relubrication of the spindle nut(� or �).

Calculation of lubrication intervals Since it is not possible to calculate all the influencing factors,the time at which relubrication must be carried out and the quantity of lubricant which must be used can only be precisely determined under actual operating conditions.If no precise data are available, the values for many applications can be taken from the table.Relubrication must be carried out at the latest when fretting corrosion first occurs, which is visible as a reddish discolourationof the raceways. The subsequent lubrication intervals must be shortened.An approximation formula can be used, however, to determinea guide value for many applications.Detailed information on calculating the grease operating life is given in the Catalogue PF 1, Monorail Guidance Systems.

Relubrication quantityper lubrication point

Any lubrication method involves loss of lubricant.The used lubricant must be collected and disposed of by methods that help to protect the environment.The handling and use of lubricants is governed by national regulations for environmental protection and health and safetyat work as well as information from the lubricant manufacturers. These specifications must be observed.

Location of the support railLocation using clamping lugs Clamping lugs are suitable for location of the linear actuator on

the adjacent construction. If the actuator is fully supported,clamping lugs must be arranged at both ends of the support railand then on both sides at intervals of no more than 300 mm, Figure 7.For heavy load conditions are present, the quantity of clamping lugs must be increased!

Location using screws For location of the linear actuator on the adjacent construction,the underside of the support rail has threaded holes at intervalsof 40 mm, Figure 8.The end distance T2 is dependent on the profiled rail length and the number of holes. It is a minimum of 15 mm and a maximum of 35 mm.
