Trusted by Industry Leaders
Complete FEAD System Design & Validation
Full-system integration of serpentine belts, automatic tensioners, and idlers ensures optimal belt alignment, tension maintenance, and accessory drive performance across the engine's entire speed range.
Low-Friction Engine Sealing Technology
Fenner's proprietary seal lip design reduces frictional torque by up to 20% compared to conventional oil seals, contributing directly to measurable improvements in engine fuel efficiency.
Durable Elastomer Compounds for Aggressive Engine Oils
Seal and belt compounds formulated using HNBR, ACM, AEM, and FKM withstand aggressive synthetic engine oils, high-temperature oxidation, and additive packages used in modern downsized turbocharged engines.
Programmable DVPR Test Rig Validation
In-house test rigs simulate customer-specific durability and performance validation requirements (DVPR), reducing OEM qualification cycles and ensuring first-time-right production launches.
NVH-Optimized Tensioner Design
Automatic belt tensioners with tuned damping characteristics maintain consistent belt tension while reducing noise, vibration, and harshness (NVH) perceived by vehicle occupants.
IATF 16949-Certified Manufacturing with Full Traceability
All engine system products are manufactured under IATF 16949 quality management, with complete lot traceability and PPAP documentation as standard for automotive OEM supply.
Why Choose JK Fenner as Your Automotive Engine Systems Partner
JK Fenner's Automotive Product Division (APD) has earned preferred supplier status with some of the world's largest automotive manufacturers through a relentless focus on quality, delivery, and collaborative engineering. Unlike catalogue-based component suppliers, Fenner works from the earliest stages of engine development programs — contributing material selection expertise, seal lip geometry optimization, and belt-tensioner dynamic simulation to help OEMs achieve their performance, durability, and NVH targets. With three dedicated R&D centres, 120+ design and validation professionals, and manufacturing facilities in Chennai, Madurai, and Hyderabad, Fenner combines global-standard engineering depth with the responsiveness and flexibility of an India-based Tier-1 supplier.
Applications Across Engine Platforms
JK Fenner engine system solutions are deployed across passenger car petrol and diesel engines, commercial vehicle powertrains, agricultural tractor engines, off-road and construction equipment, and two-wheeler/three-wheeler engines. FEAD systems drive alternators, power steering pumps, air conditioning compressors, and water pumps via single serpentine belt configurations. Timing belts provide precise camshaft synchronization in interference and non-interference engine designs. Crankshaft front and rear seals, camshaft seals, and valve stem seals ensure oil retention and contamination exclusion in critical engine locations. J.K. Fenner supplies these solutions to customers including Hero MotoCorp, TVS Motor Company, Ashok Leyland, and Wabco, among others.
