Why Blister Packaging Machines in Germany Demand Superior Industrial Drive Shafts
German blister packaging machines operate at blister rates of 450+ per minute in clean-room environments. The main transmission shaft must guarantee exact indexing of forming, filling, sealing and punching stations while absorbing thermal expansion and vibration from high-speed cam drives. Our industrial cardan shafts deliver the torsional stiffness required for millimetre-accurate positioning, critical-speed safety for spans up to 3.2 m, and angle compensation up to 15° without inducing axial thrust on servo motors. Every shaft undergoes dynamic balancing to G6.3 and is tested for continuous duty at 90 °C ambient temperature typical of pharma lines in Baden-Württemberg and Bavaria.
Engineered from 42CrMo4 alloy steel with optional carbon-fibre composite tubes, these drive shafts reduce rotating mass by up to 40 % while raising the first critical speed beyond operating RPM. The result: zero resonance, minimal maintenance and full traceability to meet German VDMA and EU Machinery Regulation 2023/1230 requirements.

Full Compliance with German & EU Machinery Regulations
All shafts carry the CE mark according to Machinery Regulation (EU) 2023/1230. They meet VDMA 24320 guidelines for rotating power transmission components and DIN 743 shaft strength calculations. German plants in North Rhine-Westphalia and Bavaria also require ATEX compliance for solvent-based blister lines – we supply explosion-proof versions with stainless steel guards and non-sparking materials. Neighbouring Austria and Switzerland accept these certificates without additional testing under mutual recognition agreements.
- EU Machinery Regulation 2023/1230 – mandatory from 2027
- DIN 743 – shaft strength & fatigue
- ISO 1940-1 G6.3 balance

How to Select the Right Drive Shaft for Your Blister Packaging Machine
- Measure maximum indexing torque on your main cam shaft.
- Confirm required working angle and axial stroke.
- Choose torque limiter type: shear bolt for cost-sensitive lines, friction clutch for high-inertia punch stations.
- Select material: carbon fibre for machines exceeding 2.5 m span.
Step-by-Step Installation Guide
1. Align flanges to within 0.05 mm using laser tool.
2. Torque bolts to 180 Nm in star pattern.
3. Grease spline with high-temperature EP2 grease.
4. Verify guard rotation before start-up.
Matching Gearboxes for Complete Power Transmission Systems
Our industrial drive shafts are designed to work seamlessly with high-efficiency planetary and helical gearboxes commonly used in German blister packaging equipment. These gearboxes deliver precise speed reduction while our shafts transmit the torque with minimal angular deviation. Typical reduction ratios range from 5:1 to 20:1 depending on line speed. The gearboxes feature case-hardened gears with AGMA 12 precision and lifetime lubrication. When paired with our cardan shafts, the complete driveline achieves overall efficiency above 97 % and service life exceeding 60 000 hours under continuous duty.
For high-speed blister lines running at 400–600 cycles per minute, we recommend our compact inline planetary series with output torque up to 12 000 Nm and backlash under 3 arc-min. The output flange matches our Hirth-serration interface perfectly, eliminating any need for adapter plates. In pharmaceutical clean rooms the gearboxes are supplied with stainless steel housings and IP69K protection. Cooling options include forced-air fans or water jackets for ambient temperatures above 40 °C.
Helical bevel gearboxes are preferred when the drive motor is mounted at 90° to the main transmission shaft. These units offer high power density and quiet operation below 68 dB. Our shafts connect directly to the hollow output shaft via internal spline, removing any additional coupling. Torque limiters can be integrated inside the gearbox or on the shaft side for maximum protection of expensive forming tools.
All gearboxes carry CE marking and are manufactured according to the latest Machinery Regulation. They undergo 100 % run-testing at full load before shipment. Typical models used in blister lines include ratios 7.5:1 for forming stations and 12:1 for sealing stations. When you specify your blister machine model we can supply the complete matched driveline package – shaft plus gearbox – with a single part number and one warranty.
Maintenance intervals for the gearbox-shaft combination reach 12 000 hours when using synthetic EP lubricants. Temperature monitoring sensors can be factory fitted for Industry 4.0 predictive maintenance. In German plants this integration has reduced unplanned stoppages by more than 75 % compared with mixed-brand systems. We also offer custom gear ratios and output flange dimensions to retrofit older lines without machine frame modification.
For large-scale production facilities operating multiple blister lines, we can supply complete power transmission skids including motor, gearbox, drive shaft, torque limiter and safety guards. All components are pre-aligned and tested as a system. This turnkey approach saves engineering time and guarantees optimum performance from day one.
