High-Pressure Liner Hoses and Modular Spray Nozzles

For demanding machining applications requiring boosted fluid pressures, Legrom provides Liner hoses with an internal reinforcement sleeve rated up to 15 bar. The nozzle program features round, flat fan, multi-hole tips and Outlineflex copper-core flexible lines for targeted jet aim.

High-pressure Liner assemblies rated up to 15 bar for deep-hole drilling cycles.
Round orifice nozzles with precision calibrated outlet diameters for spot cooling.
Flat fan spray nozzles for broad swath lubrication across milling cutter flutes.
Outlineflex copper-core flexible tubes that maintain position under fluid impulse.

Spindle Brakes and Textile Machinery Components

Legrom develops twin-shoe spindle stop brakes with concentric clamping geometry for ring spinning machinery. The balanced mechanism delivers shock-free deceleration of spindle shafts, while easyclick snap-in brake linings significantly reduce routine maintenance downtime.

Precision stainless steel transport aprons and belts for spinning machine frames.

Precision Polymer Rolling Bearing Cages

With over six decades of specialization, Legrom produces rolling bearing cages using high-grade thermoplastics including PA 6, PA 6.6, POM, PPA, PEEK and LCP. Reinforcement with carbon fiber, glass beads, graphite and PTFE lowers friction at high rotational velocity.

Configuring Modular Legrom Vario System Articulated Coolant Lines

Modular Legrom Vario System coolant lines manufactured from engineering polyoxymethylene POM are engineered to deliver precise cutting fluid streams directly into turning, milling and grinding tool engagement zones.

When specifying individual links or complete coolant assemblies, identify the required threaded connection to the machine manifold (NPT taper or BSPT pipe threads ranging from 1/8 to 3/4 inch), nominal pumping pressure and lubricant viscosity.

The ball-and-socket joints deliver high directional rigidity without shifting under severe machining vibrations or hydraulic pressure surges. Line assembly and segment length adjustments are performed using specialized Legrom assembly pliers without damaging segment rim profiles.

Calculating Flow Rates for 1/4, 1/2 and 3/4 Inch Hoses with Adapters

The Legrom Vario System is manufactured in three nominal bore configurations with inner diameters of 7.0 mm (1/4 inch), 12.7 mm (1/2 inch) and 18.5 mm (3/4 inch).

System sizing accounts for standard volumetric delivery: up to 16 l/min for 1/4 inch, up to 32 l/min for 1/2 inch and up to 72 l/min for 3/4 inch lines under operating pressures up to 6 bar.

To construct multi-stream cooling arrangements across large face milling cutters or wide grinding wheels, modular Y-junctions, in-line shut-off ball valves and step adapters allow fluid distribution from a single 3/4 inch header into multiple 1/2 or 1/4 inch flexible nozzle runs while maintaining hydrodynamic line pressure.

High-Pressure Liner Reinforcement Sleeves and Precision Spray Nozzles

For deep-hole drilling, high-feed milling of tough alloys and fluid circulation exceeding 6 bar line pressure, standard articulated links are fitted with an internal reinforcement Liner sleeve.

The protective Liner prevents segment separation during sudden pressure peaks up to 15 bar while preserving articulation flexibility and seal integrity.

The spray nozzle program includes round conical orifices from 1.5 to 9.5 mm diameter for concentrated jets, flat fan slots up to 60 mm wide for sweeping cutter flutes, multi-orifice shower nozzles and malleable Outlineflex copper-core polymer tubes that maintain custom bend angles under heavy fluid impulses.

Maintenance Protocols for Ring Spinning Machine Spindle Stop Brakes

For textile spinning mills, Legrom produces twin-shoe spindle stop brakes engineered with concentric shaft clamping. Unlike asymmetrical single-shoe stoppers, the balanced twin-shoe geometry eliminates radial bending moments on spindle bearings during emergency yarn interruption.

When scheduling routine brake replacements, specify the spindle shaft neck diameter and spindle rail pitch.

The Kniebremse easyclick variant incorporates a snap-in retention lock for rapid friction lining replacement without dismantling the actuating knee lever, significantly reducing scheduled machinery downtime across spinning room floors.

Specifying Thermoplastic Rolling Bearing Cages for High-Speed Units

Legrom rolling bearing cages are injection-molded from technical thermoplastics including PA 6, PA 6.6, POM, polyphthalamide PPA, polyetheretherketone PEEK and liquid crystal polymers LCP.

Polymer cages are substantially lighter than steel or bronze alternatives, lowering centrifugal forces on rolling elements and exhibiting low friction coefficients during momentary boundary lubrication.

Reinforcement with functional additives (carbon fibers, graphite, molybdenum disulfide, PTFE) enables dependable deployment in high-speed machine tool spindle bearings operating at continuous temperatures up to 200 °C with low heat generation.

Distinguishing German Manufacturer Legrom GmbH from Unrelated Homonyms
