LINE TECH – Swiss made Linear Technology

Bridge modules Product overview

LINE TECH bridge modules are precision, ready-to-install, modular linear systems with linear guide and two drive variants, ball screw and toothed belt drive. Cantilever axles and axles with higher intrinsic inertia are specific application areas. One size (BM4) is currently available.

Advantages

Structure

– Compact dimensions – Optimum running performance together with high load ratings and high level of rigidity with either one or two integrated, no-play linear guides – Either ball screw or toothed belt drive – Simple motor mounting by centering and thread on driving head – Greasing by central grease points – Design aligned to application possible

– Compact aluminium base profile – Ready-to-install bridge modules in any lengths – Carriages made of aluminium

LINE TECH bridge modules

Lubrication

Maintenance

LINE TECH bridge modules with ball screw or toothed belt drive are modular, ready-to-install linear units with drive.

Sealed rail guiding elements are employed.

Guides and drive are protected from external factors (such as dirt and chippings) by a steel strip / the toothed belt.

The base profile as well as the lateral profile are made of aluminium alloy and manufactured with the extrusion process.

Additional limit switches fitted on the outside, in conjunction with motors and a controller, ensure correct positioning of the carriage and provide protection against overrun.

The selected design provides for a high level of performance with the most compact dimensions.

LINE TECH bridge modules are lubricated with Microlube GBU Y 131 at the factory.

This quality grease offers outstanding properties for the guidance and screw drive elements as well.

Greasing should be carried out at regular intervals, depending on the load and area of operation. On an average, re-greasing is required every 500 hours.

All roller bearings are greased for life and thus do not require any maintenance.

Correct and adequate greasing can substantially prolong the life of bridge modules.

LINE TECH bridge modules are maintenance-free (apart from re-greasing required).

Service temperature The permissible operating temperature (between 5 and 80 °C) is determined by the synthetic materials used.

The specifications of the relevant manufacturers apply for motors and control units.

Note: Also follow here the instructions on the grease points, page 102.

Expedient load

Note on dynamic load ratings and torques The determination of dynamic load ratings and torques is based on a 50, 000 m stroke. If comparative values must be

70

calculated for a 100, 000 m stroke, the values for Mx, My, Mz and C must be divided by the factor 1.26.

With a view to serviceable life, loads of less than 20% of the dynamic load ratings have generally proved to be expedient.

Bridge modules Limit switch mounting

Limit switches

On request the following non standard limit switches are available:

The limit switches are used in conjunction with a control unit to limit the stroke (prevent overrunning of the carriage) and to define the reference position.

Note: At the factory the plus and minus limit switches are preset to a nominal stroke of 0 to +5 mm.

– PNP openers (PNP-NC) Supply: 10...30 V DC Current consumption off-load: < 10 mA Load: max. 200 mA

Limit switches / reference switch mounting overview

Note: If a lateral support rail (type LM… L/R) or a lateral profile (type BM...V/W) is selected, the limit switches can only be fitted on the opposite side.

Limit switch actuator

Special applications often require a separate reference point switch to be mounted between the positive and negative limit switches. The limit switch closest to the motor mounting (limit switch controller interface) is known as the forward limit switch.
