Yes – spiral springs can be installed even while the shaft or spindle remains assembled in the machine. To do this, the spring is extended and positioned at a 45° angle relative to the shaft, then carefully wound onto the shaft laterally. This method allows for efficient retrofitting without disassembling critical components. Precision and controlled handling are important during this process.

After approximately 20 full extension/retraction cycles, the spring reaches its final shape. Only then should inner and outer diameters be measured in the fully extended state.

Yes – when installing spiral springs in vertical position, it's recommended to place the larger (outer) end of the spring at the top. This promotes a self-cleaning effect, as gravity helps particles and debris fall out of the spiral mechanism during operation. This setup improves long-term reliability, especially in environments with chips, dust, or fluid residue.

Depending on contamination levels, the spring should be cleaned daily or weekly. Apply a light technical oil film afterward. Do not use grease, as it restricts spring movement.

The installation orientation directly influences the spring’s construction and function. Each spring is made specifically for horizontal or vertical use. Switching the orientation afterward is not recommended.

VORPCOs Standard springs are rated for speeds up to 60 m/min which makes them suitable for Robotics and Automation. Higher speeds may require customised solutions—please contact us for options.

What should I pay attention to when unpacking the spring? The spring is shipped in a tensioned (compressed) state, held in place by steel fixation straps. Do not release these straps before the spring is secured on the machine or with a fixation clamp. Always: Ensure the spring is properly supported or guided during unpacking Wear protective gloves and eye protection Avoid releasing the spring in free air — uncontrolled opening can lead to injury or damage Fully extended springs may over extend and lose shape Every spring is supplied with handling and safety instructions — these must be followed carefully.

In horizontal installation, the spring is manufactured with greater coil overlap to reduce sagging. In vertical orientation, longer extension lengths are possible, but the spring requires more initial force to operate reliably against gravity.

Use hardened carbon spring steel with surface treatment for dry environments. In areas with moisture or coolant exposure, stainless steel is recommended. Keep in mind that stainless versions offer lower spring force and are not available in all sizes.

The inner diameter of the spring should be at least 6 mm larger than the outer diameter of the machine part being protected (e.g., a spindle or shaft). This ensures enough clearance for centering flanges and allows the spring to move freely. We’re happy to assist with precise sizing.
