Tschudin + Heid manufacturing development and precision facilities

Swiss manufacturing enterprise Tschudin + Heid AG has maintained continuous precision engineering production for over one hundred and thirty years. Founded in 1892 in Waldenburg within the Basel-Landschaft canton, the company originally focused on miniature precision clockwork parts.

Beginning in 1900, the factory manufactured under the registered name Tschudin + Heid, transitioning in 1931 into a joint-stock entity that remains an independent family-owned business.

Today the facility operates a fleet of multiaxis computer numerical control machining centers, high-accuracy grinding machines, and dedicated assembly lines, supplying high-grade mechanical components to machine tooling, instrumentation, and medical sectors.

Design principles and performance of TH cylindrical roller guides

Cylindrical longitudinal roller guides in the TH product line represent integrated structural modules for high-precision machine tools, measuring instruments, and tooling fixtures.

The standard assembly comprises an outer hardened guide bushing, a ground guide column, and a dedicated roller retainer.

The key engineering advantage of this roller architecture lies in the linear contact line along the rolling profile, enabling a TH profiled roller to support up to twelve times higher mechanical loads than a ball bearing of identical diameter.

This configuration ensures exceptional rigidity, elevated load-bearing capability, and play-free linear motion across heavy machine tool carriages.

Precision roller retainers engineered for smooth linear motion

Ready-to-install Rollenkaefige roller retainers produced by Tschudin + Heid serve as primary load-transmitting components in linear motion assemblies.

The factory manufactures retainer bodies from high-strength lightweight aluminum alloys, wear-resistant bronze, or specialized engineering polymers according to operational ambient requirements.

Accurate pocket geometry guarantees uniform spacing of rolling elements along the entire guide length, preventing roller skewing and localized stress spikes. These retainers minimize motion resistance and deliver vibration-free travel smoothness during rapid high-frequency machine reversals.

Custom cylindrical rollers to DIN 5402 for demanding mechanisms

The specialized cylindrical roller manufacturing portfolio of Tschudin + Heid includes standardized dimensions per DIN 5402 as well as tailor-made geometries built to customer drawings. Rolling elements are formed from high-alloy bearing steel subjected to thorough hardening and fine surface honing.

Roundness deviations are held within fractions of a micrometer, guaranteeing uniform pressure distribution across contact zones.

These precision rollers are widely integrated into heavy longitudinal guideways, rotary indexing tables on numerical milling machines, coordinate measuring systems, and critical aerospace motion assemblies.

Industrial FLM air blow nozzles and low-noise Silent series

Pneumatic air blow nozzles and handheld units across the FLM series provide efficient cleaning of machining zones, purging metal chips, grinding dust, and coolant residues from clamped workpieces.

The unit mounts directly onto flexible pneumatic hose ends and operates via intuitive lateral thumb pressure, allowing operators to smoothly meter air discharge.

The specialized FLM-1R V3 Silent modification incorporates an integrated acoustic diffuser that significantly reduces air jet decibels without diminishing blowing momentum. This design markedly improves ergonomic workplace conditions across machining and final assembly lines.

Technical selection guidelines and maintenance rules for TH guides

Ensuring extended service life for Tschudin + Heid cylindrical linear guides and retainers requires strict compliance with factory fit tolerances and lubrication schedules. Unit selection relies on column diameter, required stroke length, and calculated equivalent dynamic operating load.

During mounting of bushings and guide columns, technicians must verify alignment and parallelism of mounting surfaces to prevent edge loading on rolling elements.

Routine maintenance protocols mandate regular purging of swarf and contamination from raceways followed by application of recommended anti-wear industrial greases.
