Temper

What Temper does

Temper Corporation is a privately held, family-owned custom precision-manufacturing company founded in 1969 and headquartered in Fonda, New York. It designs and produces specialized mechanical components — constant force adjustable spacers (Load Rings), high-temperature metal seals rated to 2000°F, Speed Sense magnet rings for motion and position sensing, precision machined parts, and Doctor Preload bearing adjustment tools — primarily for aerospace and defense, heavy equipment and off-highway vehicles, oil and gas, power generation, and motion-control customers. Core manufacturing is performed in-house at an ISO 9001:2015 certified facility using CNC machining, cylindrical grinding, EDM, wire EDM, laser cutting and etching, form rolling, and heat treating, with tolerances as tight as 0.0001 inches. The firm holds four granted US patents and one pending application covering its core inventions.

The business operates on a direct-to-customer, quote-based model with custom engineering consultation delivered by the Director of Manufacturing and Director of Engineering. Revenue is generated primarily through one-time hardware sales of custom-engineered components, supplemented by in-house machining and design/engineering services. Distribution is direct (phone, email, website) with no intermediaries, and channel reach is extended through industry trade shows (MINExpo, AeroDef, ConExpo, Mid-America Trucking Show) and technical content marketing. The firm is a registered US Federal Contractor and a certified Women-Owned Small Business (WOSB), and operates a wholly-owned subsidiary, Temper Axle Products Corporation, focused on railway-axle load rings. With 11-50 employees and production capacity of over 2 million rings per year, Temper is a small but technically specialized niche manufacturer with a 50+ year operating history under current ownership of Cynthia DeKuiper.

• High Temperature Metal Seals Roll-formed single and multi-convolute spring seals designed for temperatures up to 2000°F, using Inconel and Hastelloy materials with optional silver or gold coating. Used in commercial and military aircraft, oil refineries, nuclear reactors, and fuel cells.
• Precision Machined Parts Custom precision machining services including CNC turning and milling, cylindrical grinding, EDM, heat treating, laser cutting and etching, multi-spindle lathes, and surface grinders, with tolerances as tight as 0.0001 inches.
• Temper Constant Force Adjustable Spacers (Load Rings) Precision rings that function as predictable, constant force elements, fabricated from ductile, high-strength stainless alloys. Compress at constant force and provide repeatable spring back, eliminating the need for measuring and shimming bearings.
• Speed Sense Magnet Rings Low-profile, patented magnet rings used in speed control, direction sensing, and counting applications. Constructed with stainless steel outer shield and strontium ferrite magnet bonded with nitrile rubber; perform in temperatures up to 250°F, high pressure, and corrosive environments.
• Elevator Magnet Wheel Assembly Captured magnet ring wheel assembly used as a replacement part for elevator control systems, specifically designed for use with Motion Control Engineering, Inc. (MCE) elevator controllers.
• Temper Axle – Doctor Preload Bearing Adjustment Tool Patented bearing adjustment tools and Temper-Loc spindle nuts that allow technicians to quickly and accurately adjust wheel end bearings to SAE standard light preload settings while measuring preload forces; fleets report up to 30% increases in tire life.
• New Product Development (Belleville Springs, Adjustaville Hybrid Springs, High Force Spacers) Custom product development services for new spring and spacer products, including Belleville Springs, Adjustaville hybrid springs combining Temper adjustable spacer and Belleville spring design, high force spacers with hardened faces (Rockwell C60), and self-interlocking stacking Belleville discs.
• Temper Smart Press Automation Equipment Custom designed hydraulic Smart Presses using Baldor servomotors and Direct Automation controllers for high force, super-accurate bearing-adjusting applications, with capacities up to 300,000 pounds.

Broad incumbents

• John Crane (Smiths Group): Global leader in mechanical seals, seal support systems, and reliability technologies for oil & gas, power, and chemical processing — overlaps with Temper's high-temperature refinery and nuclear sealing products but operates at much broader scale across global Tier 1 process-industry customers.
• Garlock (EnPro Industries): Large industrial sealing manufacturer (gaskets, packing, expansion joints) with broad chemical/energy/industrial coverage — overlaps with Temper's high-temperature metal seal line but at significantly larger scale and product breadth, including polymer- and graphite-based sealing where Temper does not compete.
• Trelleborg Sealing Solutions: Global leader in polymer and elastomer sealing, bearing, and damping products for aerospace, automotive, and industrial OEMs — adjacent to Temper's aerospace/defense high-temperature seal opportunities but with a much broader polymer-based product portfolio and global footprint.
• MW Industries: Holding company over multiple precision spring, fastener, and engineered component manufacturers (including Century Spring, Lee Spring, Boker's adjacent brands) — broad incumbent peer grouping with direct technical overlap to Temper's Load Ring, Belleville, and custom machined components businesses.

• Lee Spring: Custom and stock spring manufacturer offering Belleville disc springs, wave springs, and compression springs — directly comparable to Temper's 'Adjustaville' hybrid Belleville/load-ring products and other engineered spring/spacer offerings for industrial assemblies.
• Bunting Magnetics: Manufactures bonded and sintered magnetic products, magnetic assemblies, and sensor magnets for industrial motion control and speed sensing — the closest direct peer to Temper's Speed Sense magnet ring product line used in hydraulic, elevator, and heavy-equipment feedback applications.
• Rotor Clip: Manufacturer of retaining rings, constant-section rings, and wave springs used in bearing and mechanical assemblies — comparable to Temper's roll-formed ring/spacer products, particularly the Load Ring and high-temperature seal rings, in overlapping industrial customer applications.
• Smalley Steel Ring Company: Manufactures wave springs, constant-force springs, and retaining rings from coiled strip stock — direct technical parallel to Temper's Load Ring family, which is also a roll-formed constant-force spacer/spring device serving bearing preloading and similar assembly applications.
• Bal Seal Engineering: Custom-engineered sealing, spring-energized seals, and conductive elastomer products for aerospace, medical, and industrial markets — directly comparable to Temper's high-temperature metal seals and engineered spacer products, with similar application-engineering sales motion.
• Boker's, Inc. Manufacturer of precision metal stampings, shims, washers, and spacers serving OEM industrial customers — directly comparable to Temper's spacer/shim business and custom precision machined parts, with similar small-batch-to-high-volume flexibility.
