Product Overview

Product Background


eLINE Ball Screws are available from stock as complete assemblies,with screw-in or flanged nuts.The pre-finished machining is easily combined with the fixed bearing LGL(support block with bearing) as a complete package.The eLine products can simplify the choices for many customer-specifiedtransport applications.The part number specification and ordering process for new applicationscan also be handled more effectively.Relaxed tolerances provide very economical linear motion solutions. Everynut is assembled with clearance.With seals.Cost savings are always a priority with the eLINE.The load capacity of the support bearing is critical. By friction welding the

bearing forward, we were able to enlarge smaller screw diameters andincrease the load bearing capacity.

Advantages

Grooved Ball Bearingwith Safety Ring, LAD series

Storage with grooved Ball Bearings

Angular-contact thrust bearing with Nut, LAL seriesThe end bearing LGL with angular-contact ball bearing in an X arrangement makesan ideal accessory.

High load capacity Very easy mounting with the flanged housing Corrosion-resistant housing Seals provide protection from contaminants Simple preload of the fixed bearing Maintenance free for most application due to the large lubricant reservoir with

initial greasing

Economical turnkey solutions made easy.

Part Number

R3417 008 02

The nut has to be lubricated withlubricant via the lube port before the ballscrew is started.

The relubrication is valid for Ball ScrewAssemblies with seals.

DIN51825Rexroth

For lubrication, we recommend RexrothDynalub 510, a lithium-based high-

performance grease specially developedfor linear motion systems. It is notablefor offering excellent water resistanceand protection against corrosion.

Mounting

Storage

Condition as delivered

The various mounting steps aredescribed below. Proceed in reverseorder when removing the nut from thescrew. Take particular care not to

damage the nut, screw or internalcomponents, as this could result inthe premature failure of the ball screwassembly.

The nut unit may only be mounted using a mounting arbor. The outer diameter of thearbor should be approx. 0.1 mm smaller than the root diameter of the screw. Inmost cases, the transport arobor on which the nuts are delivered may be used tomount the nut. The end of the screw thread must be chamfered in order to preventdamage to the seal and the internal components of the nut unit.

Rexroth Ball Screw Assemblies arenormally lubricated with NLGl 2 grease

when specified. This initial lubricationallows for relubrication using either oilor grease. If you use a different type oflubrication, please ensure that the otherlubricant can be mixed. In special cases,you can specify a corrosion-preservedBall Screw Assembly.

Important:The selected lubricant must be in the nutbefore the machine is started.

Cleaning:Various cleaning agents can be used to

degrease and wash the assembly: Aqueous cleaning agents Organic cleaning agentsImmediately after cleaning, thoroughlydry all parts, then apply a preservativecoating or anti-corrosion oil.In all cases, take care to observe theappropriate legal regulations(environmental protection, health andsafety at work, etc.) as well as thespecifications for the cleaning agent(e.g. handling).

Ball screw assemblies are high-qualitysystems that must be treated with duecare. In order to prevent damage andcontamination, the elements should notbe removed from the protectivewrapping until immediately beforeinstallation. Once they have beenremoved from the packaging, they mustbe set down on V-shaped cradles.

The nut is to be mounted as follows:

Remove the rubber ring from one end ofthe mounting arbor.

Push the mounting arbor with nut until itengages with the end of the thread.The arbor must make contact with axialclearance.Carefully turn the nut unit onto thethread, applying only light axial pressure.

Mounting steps Installation in the MachineIt is not normally necessary to remove the

preservative coating before installation.

If the ball screw is contaminated itmust first be cleaned (seeCleaning) and reoiled

Push the nut unit into the mountingbore, taking care to avoid anyimpacts or misalignment.

Tighten the mounting screws using atorque wrench if necessary. Maximumtightening torque for the steel/steelmaterial pairing(Rm 370 N/mm2), see table.

For the steel/aluminium andaluminium/aluminium material pairings(Rm 280 N/mm2), the maximumtightening torques specified in thefollow table apply.When screwing into aluminium, thelength of thread engagement shouldbe at least 1.5 times the screwdiameter.
