What Kaller does

Kaller is a Sweden-based industrial brand specializing in nitrogen gas springs and gas hydraulic suspension systems for tool-and-die, automotive, and defense applications. The company was founded in 1876 and markets itself as the original gas spring brand in press tools, with products compliant with ISO standards and several major OEM specifications (FCA Fiat-Chrysler 075.90.60, GM 90.25.08, Ford WDX, Renault). Its core product portfolio covers a wide force range from 1,700 N to 200,000 N across multiple gas spring series (X, XG, XF, XMS, TX, TU, TUS, TUR, TMS), supplemented by delayed return units, piercing/forming/roller cam units, lifters, manifold systems, industrial counterbalance cylinders, gas hydraulic suspension systems (including defense applications such as the Patria AMV Nordic IFV concept), and an IoT-enabled Remote Pressure Monitoring system with sensors, base stations, handheld readers, and Toolmind repeaters.

All Kaller products are manufactured exclusively by Strömsholmen in Tranås, Sweden. In early 2025, Strömsholmen was acquired by a new owner, which the company describes as the start of a new chapter of growth and investment. Kaller sells through a global distributor network plus direct sales from headquarters, and supports customers with a self-service digital ecosystem including a free Gas Spring Database of approximately 2,000 products, 3D CAD files, calculators, the KALLER Academy e-learning platform, and a Die Follow-Up service. The customer base spans tool-and-die shops, hot stamping operations, electric vehicle manufacturers, white goods and HVAC producers, automotive OEMs, drill rig builders, agriculture and construction equipment makers, actuator and automation system integrators, and military vehicle programs.

The business model is B2B specialty industrial component sales with quote-based, non-publicly-disclosed pricing distributed through authorized resellers and direct enterprise engagement. Revenue mechanics are not publicly disclosed; monetization appears driven by unit sales of gas springs and related components, with the newer Remote Pressure Monitoring product line introducing a potential recurring-data or service layer on top of the installed base.
