What PT Tech, Inc. does

PT Tech, Inc., operating as PT Tech by Timken, is an industrial power transmission component manufacturer founded in 1978 and headquartered in Sharon Center/Wadsworth, Ohio. The company designs and produces a focused portfolio of heavy-duty drivetrain components — Hydraulic Power Take-Off (HPTO) clutches, multiple torque limiter series (FMD, UJT, SLQ, SL, CMD), caliper disc brakes (CDB, HCDB), motor-mounted brakes (NBE, VFDB), enclosed wet brakes, combination gearboxes with integrated clutches and brakes up to 1200 HP, and over-running clutch couplings (SGK, SGS, KDK) — together with the AeroTorque wind turbine torsional control product line. Underlying technology centers on proprietary microprocessor-controlled engagement systems, custom friction materials, patented torque-limiting mechanisms with tamperproof color-coded spring settings, and a Generation3 controls platform with Bluetooth diagnostics, HPTOLink App, and SAE J1939 CANbus integration.

The company serves B2B OEM customers in mining, aggregates, tunnel boring, metals/steel, wind energy, material processing, wood-waste recycling, marine/offshore, and mud-pumps/fracking end markets, supplying components designed into the drivetrains of crushing equipment, scoops, shield haulers, TBM cutterheads, rolling mills, wind turbine gearboxes, kilns, conveyors, and grinders. PT Tech does not sell replacement parts directly to end users; distribution is through authorized OEM and distributor channels, with international reach provided by the global Timken network following the 2017 acquisition by The Timken Company (NYSE: TKR). Operations include a primary manufacturing facility in Ohio, regional offices in Wuxi, China and São Paulo, Brazil, ISO 9001 w/Design certification, and a headcount of 101-250 employees.

Revenue is generated through direct OEM sales of custom-engineered hardware and through authorized distributors, with quote-based pricing tied to application specifications, quantities, and integration requirements. No public pricing or revenue figures are disclosed. The company has built a 45-year track record of industry-first product launches, including the first zero-maintenance friction torque limiter (1980), first TBM clutches used in the Channel Tunnel (1986), first microprocessor-controlled wet HPTO (1999), and the WindTC asymmetric torsional control system (post-2013 AeroTorque launch).

Products and services

• HPTO® Hydraulic Power Take-Off Clutches Hydraulically applied friction clutches for diesel engines and electric motors, available in dry and wet disc pack configurations from 80 HP to 1600 HP, featuring microprocessor-controlled push-button engagement with patented software for consistent startup and operator abuse protection. The Gen3 Series adds Bluetooth connectivity, data logging, HPTOLink App support, and tapered bearing designs combining transverse and direct drive configurations.
• Torque Limiters (FMD, UJT, SLQ, SL, CMD Series) Continuously engaged friction-type torque limiters with tamper-proof, color-coded spring cup torque settings that require no resetting after shockloads. FMD series handles high horsepower and limited space applications on the high-speed side of drive systems. UJT series is maintenance-free with factory pre-set torque. SLQ offers economical standard torque and energy protection. SL fits mining applications with hollow motor shaft mounting. CMD provides compact multiple disc design for levelers and flatteners on steel processing lines.
• Combination Gearboxes with Integrated Clutches and Brakes Custom gearboxes with internal wet clutches and integrated wet brakes up to 1200 HP (895 kW), available with integrated hydraulic pump, filter, manifold, and clutch controller for simplified system packaging. The PTT-477 Series offers enclosed wet brake on intermediate shaft with increased durability and same mounting footprint as retrofitted legacy gearboxes.
• Caliper Disc Brakes (CDB and HCDB Series) Industrial caliper disc brakes outperforming drum brakes with greater thermal capacity and resistance to heat checking, fitting AIST standard mounts with easy one-wrench adjustment and friction puck replacement. The HCDB hydraulic series features wear-compensating design with consistent operating clearance and quick friction puck replacement, directly replacing existing drum brakes.
• Motor Mounted Brakes (NBE and VFDB Series) Dynamic motor brakes maintaining full torque at high speeds and addressing low frequency friction-induced vibration issues. NBE series operates in dynamic situations where typical motor brakes would sacrifice dynamic friction coefficient. VFDB series provides variable frequency dynamic motor braking for high-speed stopping scenarios where holding brakes are insufficient, with higher maximum engagement speeds than competitive products.
• Enclosed Wet Brakes (WBLT Series) Oil-cooled hydraulic brakes performing dual functions as spring-set parking brakes and master cylinder operated dynamic service brakes for underground mining vehicles, including models such as the WBLT-517-381-0.
• MCB Hydraulic Service Brakes Hydraulic service brakes for off-highway vehicles, designed to brake equipment up to 33,000 kg with multiple caliper per wheel configuration.
• Clutch Couplings (SGK, SGS, KDK Series) Over-running clutch couplings combining sprag-type overrunning clutches with gear couplings, with SGK offering dropout center section for ease of service and up to 1.5° angular misalignment per gear half. SGS series serves creeper drives, inspection drives, inching drives, and turning gear applications in power plants and mills. KDK kiln drive couplings prevent centrifugal explosion from uncontrolled reverse rotation of kilns.
• Conveyor Braking Systems Custom conveyor braking packages available with standard open loop systems or smart closed loop systems using PLC-controlled proportional valves for consistent stopping time regardless of belt load, integrating Sime and Deliner caliper technology with Allen-Bradley PLCs and PID loop control.
• WindTC™ Torsional Control System Asymmetric torsional control device for wind turbines that treats forward and reverse torques differently, reducing loading from torsional reversals by 40% and reducing drivetrain oscillations by 50-70%, protecting gearboxes and bearings from damaging negative torque loads and extending gearbox life.
• WindTM Torque Monitoring Service Service that monitors and records torque loads in wind turbines for both forward and reverse torque during 3-6 week trial periods, storing the 100 worst events in each direction for diagnostics and drivetrain protection planning.
