hsi SPRÄÅ»YNA ROZCIĄGANA Z 2 OCZKAMI 3×150 mm tension spring (HS 394100)

hsi SPRÄŻYNA ROZCIĄGANA Z 2 OCZKAMI 3×150 mm tension spring (HS 394100) is an extension spring designed for mechanical assemblies and repair tasks where a compact spring with looped ends is required. The spring has a coil profile and two end loops that allow secure mounting in a wide range of devices. Its 3×150 mm designation indicates the wire/coiling and overall length characteristics suited to light- to medium-duty tension applications.

Advantages

The spring provides reliable tensile force with predictable elastic performance over repeated cycles and features looped ends for straightforward attachment and removal. Its compact 150 mm length and consistent coil winding enable space-efficient installation and accurate force transfer. The steel coil construction delivers dimensional stability and practical lifetime for common maintenance and replacement tasks.

Suitable for

• Small mechanical linkages and levers
• Appliance door or latch tensioning
• Replacement spring in garden and power tools
• Repair and maintenance of industrial assemblies with limited space

Key specifications

• Type: extension (tension) spring with two looped ends
• Nominal wire/coil designation: 3×150 mm
• Overall free length: approximately 150 mm
• End fittings: closed loop eyes on both ends for hooking or pin mounting
• Material: steel coil suitable for mechanical tension use

How to use

Install the spring by hooking the looped ends onto pins, hooks or mounting points in the assembly so that the spring is under tension when the mechanism is in its operational position. Ensure attachment points are aligned and able to bear the spring load without lateral stress. Avoid forcing the spring beyond its elastic limit; always use the correct mounting orientation so the coils are free to extend and retract without interference.

Usage recommendations

Before installation, check that mounting pins and hooks match the loop diameter and that surrounding components do not abrade the coils during movement. For safety and longevity, inspect the spring periodically for corrosion, deformation or loss of elasticity and replace when wear is evident. When used in environments with higher moisture or chemical exposure, consider protective coatings or a corrosion-resistant alternative.
