What Reliance Precision does

Reliance Precision Limited is a UK-headquartered, family-owned precision engineering company founded in 1920 and controlled by the Selka family through Reliance RG Limited. Operating from its Rowley Mills headquarters in Huddersfield, UK, with a wholly-owned manufacturing subsidiary in Bandon, County Cork, Ireland, the company designs and manufactures micron-precision electro-mechanical components and sub-assemblies for two primary verticals: Defence & Space and Life Sciences. It celebrated its centenary in 2020 and currently employs between 251 and 500 people.

The company's core product portfolio under the Reliance Technology brand includes precision gears, worm gears, racks and pinions, rack actuators, Reli-a-Flex flexible couplings, and quadrupole mass filters. Manufacturing capability is anchored by an ISO 7 optical cleanroom with laminar flow to ISO 4, coordinate measuring machines (CMMs), and proprietary Ion Flight Modelling software that simulates ion trajectories to accelerate quadrupole mass filter design. The company manufactures quadrupole mass filters to 3-5 micron parallelism and is positioned as the largest independent manufacturer of these process-critical components used in mass spectrometry. Sub-brands include Reliance Technology (standard product range) and Reli-a-Flex (couplings).

Reliance generates revenue through direct B2B sales of hardware (components and sub-assemblies) to enterprise OEMs and system integrators, with pricing negotiated per customer project. Go-to-market relies on enterprise field sales, an active trade show presence at Precisiebeurs, the Engineering Design Show, Analytica, and Space-Comm Expo, and inbound enquiries through the company website. The company operates an in-house apprenticeship scheme that has run for over 60 years and currently supplies approximately 34% of its workforce, including senior operational leaders who began as apprentices. Named customers include Airbus (defence and space contracts) and Malvern Panalytical (analytical instrumentation).
