What Denecke Leuzinger AG does

Denecke + Leuzinger AG is a privately held, family-owned Swiss distributor specializing in mechanical power transmission components. Founded in 1949 in Glarus and now headquartered in Schwanden (Canton of Glarus), the company operates as a third-generation family business under the Leuzinger family, with a wholly owned branch in Granges/Sierre (Valais) opened in 2015. The product portfolio spans approximately 40,000 standard articles organized around V-belts, timing belts, V-ribbed belts, roller chains, couplings, roller and spherical plain bearings, sealing elements, rubber-metal anti-vibration mounts, and ancillary drive accessories such as pulleys, clamping bushes, and tensioning tools. Denecke + Leuzinger holds Swiss representation rights for several major international manufacturers, including ContiTech (since 1995), Bando (since 2018), SWR/SANWU (since 2001), PIX Transmissions, Timken Europe (since 2025), and Arntz Optibelt (from 2026).

The firm's underlying technology is conventional industrial distribution combined with in-house customization: an on-site workshop performs polyurethane timing-belt welding, CNC cutting, and modification of standard parts to customer-specified lengths or configurations. Inventory is held across approximately 2,200 m² of warehouse space at the Schwanden headquarters, supported by a roughly 600 m² facility in Granges that focuses on bearings and general industrial supplies. Distribution is conducted through direct field sales at both physical locations, a B2B online shop for registered customers, downloadable product catalogs in four languages (German, French, Italian, English), and telephone/email consultation including drive calculations. Pricing is not publicly disclosed and is quotation-based, with 30-day payment terms and unit pricing for the standard catalog of 40,000 articles.

Revenue is generated exclusively through hardware sales of mechanical drive components and related accessories to industrial customers in manufacturing, maintenance, and repair operations across Switzerland. The company serves as a one-stop mechanical-power-transmission supplier, combining breadth of stock, custom modification capability, technical consultation, and manufacturer representation. The firm operates without external investors, has no disclosed funding rounds, and reports headcount in the 1-10 range, with no publicly available revenue figure.

Products and services

• V-belts Trapezoidal drive belts that non-positively transmit torques in mechanical drive systems, available as encased or raw edged variants with profile, length, and material options varying by application requirements.
• Coupling belts / Reverse idler belts Black reverse idler belts designed for use with reverse idlers without controlled slip, and grey coupling belts designed for controlled slip and silent coupling engagement.
• Power belts / Composite V-belts Drive belts for high impact and non-uniform loads that ensure safe transmission of high torques and power at large centre distances, consisting of interconnected individual belt strands with cover plate.
• V-belt pulleys Grooved pulleys and machine elements that are important components of V-belt drives, including standard or taper V-belt pulleys, aluminium cone pulleys, variator and fixed pulleys for wide V-belts, and adjustable V-belt pulleys.
• Roller bearings / Spherical plain bearings High quality roller and spherical plain bearings from manufacturers including NTN, SNR, SKF, FAG, NKE, Timken, DURBAL and others, with economical alternatives available on request.
• Timing belts / Clamping plates Modern timing belts consisting of tension member, teeth, back and protective fabric, available in rubber or polyurethane, manufactured endless or by the meter with polyurethane meter material welded to desired length in-house.
• Timing belt pulleys Precision components manufactured using milling tools for accurate pitch ensuring precise tooth engagement, available ex stock either pre-bored or with taper clamping bush system.
• Timing bars / Flanged pulleys Toothed cylinders used as blanks for producing customized timing belt pulleys, made of steel or aluminium depending on profile.
• V-ribbed belts Also known as ribbed belts, Poly-V belts, Micro-V belts or Multirib belts, non-positively transmitting torques with relatively small profile height reducing bending resistance for high transmission ratios.
• V-ribbed belt pulleys Mechanical drive components also known as poly-V-pulleys or ribbed pulleys, used for high transmission ratios with small pulley diameters, reverse idlers and high belt speeds.
• Roller chains / Sprockets for roller chains Positive-locked drive elements usually made of steel that transmit high torques without slip and have very long service life, with popular sprockets, chains, sprocket sets, chain tensioners, gliders and links supplied from warehouse stock.
• Elastic and rigid couplings Machine elements that transmit torques and rotational speeds between two shafts, with connections that can be rigid, separable or elastic, including elastic couplings, matching spacers, bolts, buffers, sleeves and clamping bushes.
• Clamping bushes / Bolt-on hubs / Weld-on hubs / Intermediate sleeves (Taper system) Machine elements establishing replaceable clamping connections between shaft and hub for V-belt pulleys, toothed belt pulleys, chain wheels, and couplings, with taper system clamping bushes always supplied with keyway.
• Clamping sets (type DL) Standardized machine elements (type DL) establishing non-positive and backlash-free connections between shaft and hub, where torques and axial forces are frictionally engaged, similar in design to Ringspann, KTR, Bonfix and Bikon models.
• Motor clamping slides / Motor clamping rails Ideal mounting base for any motor enabling easy, correct pre-tensioning of belt drives.
• Tensioning rollers / Idler pulleys / Universal tensioners Tension rollers, sprocket sets, chain slides and belt tensioning pulleys used to adjust preload force in rotary drives with fixed shafts; do not transmit power but can improve performance.
• Flat belt pulleys / Flat belts Machine elements and important components of flat belt drives where power is non-positively transmitted by friction, manufactured as arm-type pulleys, floor pulleys or solid pulleys, all with crown to prevent belt slipping.
• Belt accessories Tools for correct belt installation and maintenance including VSM-1 tension gauge for frequency measurement of V-belts and timing belts, Optikrik tension gauge, Krikit tension gauge for V-ribbed belts, and Conti Laser Aligner for alignment checking.
• Sealing elements Comprehensive range including radial shaft sealing rings (Simmerrings), O-rings, V-rings, axial shaft sealing rings (gamma rings), rubber gaskets, sealing paper, round rubber cord, VK closure caps, and SKF Speedi-Sleeve shaft repair sleeves.
• Rubber-metal anti-vibration mounts Standard elements for vibration damping manufactured from rubber mix (NBR 55 degree Shore A) and steel (galvanised St 37), used for resilient mounting of drives, motors, pumps, and compressors, including round buffers and stop buffers in various forms.
