KTR BAUMANNEX 65 Resilient Ring Coupling — Dust and Shock Resistant for Saudi Mining OperationsThe KTR BAUMANNEX 65 is a resilient ring coupling specifically designed for mining and aggregate processing applications where dust, shock loads, and high ambient vibration are constant challenges. The rubber ring elements absorb both torsional vibration and radial shock loads, extending coupling and bearing life in Saudi mining equipment where other coupling types fail within months.Ma aden phosphate mining operations in Ras Az Zawr use BAUMANNEX 65 on primary crusher drives and conveyor head drives where the combination of high shock loads and abrasive dust would quickly destroy precision-engineered couplings.Product SpecificationsManufacturer: KTR Kupplungstechnik GmbH. Torque: 200–450 Nm. Design: Resilient rubber ring. Hub: steel. Bore range: 14–55mm. Max speed: 6,500 RPM. Temperature: -30C to +80C.Frequently Asked QuestionsQ1: In high-dust/high-shock mining, inspect every 3 months, replace every 12–18 months.Q2: Yes — designed specifically for conveyor head drives, stacker/reclaimer drives, and crusher feeder conveyors in open-pit mining.

Non-standard bores: 2–3 weeks from Germany.Q4: BOWEX 65 handles reversing operation without additional wear. Up to 1 million reversing cycles.Q5: Yes — AISI 316 stainless versions available for Red Sea coastal applications and offshore platforms.

KTR BOWEX 80 Curved Tooth Coupling — Medium Power Applications Across Saudi Industrial SectorsThe KTR BOWEX 80 delivers 450–900 Nm torque capacity in a curved tooth design, bridging the gap between compact couplings and heavy industrial shaft couplings. For Saudi industrial operators — cement plants, steel mills, and water treatment facilities — the BOWEX 80 provides misalignment tolerance and torsional flexibility for heavy pump and fan drives.The BOWEX 80 external tooth geometry allows up to 75mm bore capacity, accommodating large pump shafts in municipal water treatment plants and desalination facilities across Saudi Arabia.Product SpecificationsManufacturer: KTR Kupplungstechnik GmbH. Torque: 450–900 Nm. Hub: case-hardened steel. External diameter: 140mm. Bore range: 20–75mm. Max speed: 5,600 RPM. Misalignment: 1 degree angular, 0.7mm radial.Frequently Asked QuestionsQ1: 75mm with keyway. For larger shafts, specify BOWEX 100 or BOWEX 120.Q2: Yes — the curved tooth design handles VFD-generated torsional vibration without coupling failure.Q3: Inspect teeth for dust ingress every 6 months. Replace complete set every 3–5 years.

KTR CURVFLEX 65 Disc Coupling — All-Metal Flexible Coupling for Extreme Temperature Saudi ApplicationsThe KTR CURVFLEX 65 is an all-metal flexible disc coupling designed for extreme temperature applications (up to 280C) where polyurethane or rubber elements would degrade rapidly. For Saudi steel industry, glass manufacturing, and heat treatment facilities — where process temperatures exceed rubber coupling limits — CURVFLEX 65 delivers flexible shaft connection without thermal degradation.Saudi steel re-rolling mills in Jeddah and Jubail use CURVFLEX 65 on furnace conveyor drives where ambient temperatures reach 150C+ near the furnace.Product SpecificationsManufacturer: KTR Kupplungstechnik GmbH. Torque: 160–450 Nm. Design: All-metal disc pack (stainless steel). Temperature: up to 280C. Bore range: 14–55mm. Max speed: 8,000 RPM.Frequently Asked QuestionsQ1: Above 120C ambient, polyurethane elements degrade rapidly. CURVFLEX 65 is recommended above 100C continuous operation.Q2: 0.5 degree angular — similar to standard jaw couplings. For higher misalignment, specify CURVFLEX 80 with 1 degree angular capacity.

KTR FLENDER N-EUPEX A+ 90 Pin Coupling — Extended Service Life for Long-Duration Saudi Heavy IndustryThe KTR FLENDER N-EUPEX A+ 90 is the extended-service-life version of the N-EUPEX pin coupling — featuring larger diameter pins and reinforced rubber bushings that provide 2x the service life in continuous-duty heavy industrial applications.SABIC affiliates using N-EUPEX A+ 90 on large process pump drives report 4–6 year coupling replacement intervals vs. 2–3 years for standard pin couplings — significant maintenance cost reduction in large plants with 50+ process pumps each.Product SpecificationsManufacturer: KTR (FLENDER brand). Torque: 450–1,000 Nm. Design: Reinforced pin and bushing (A+ version). Hub: nodular cast iron. Bore range: 25–85mm. Max speed: 4,200 RPM. Service life: 2x standard N-EUPEX.Frequently Asked QuestionsQ1: A+ version is approximately 30–40% higher cost but delivers 2x the service life — net cost per year is lower. RAZZ recommends A+ for continuous-duty critical applications.Q2: Yes — ATEX Zone 1, 2, 21, 22 versions available for hazardous area process pump applications.

KTR FLENDER N-EUPEX DS 80 Heavy Duty Pin and Bushing Coupling — Maximum Durability for Saudi Cement and SteelThe KTR FLENDER N-EUPEX DS 80 is the heavy-duty version of the classic pin coupling design — double-segment pin and bushing arrangement delivers maximum durability for the harshest industrial environments. For Saudi cement plants, steel mills, and heavy mining equipment — where equipment operates 24/7 under high shock loads — the N-EUPEX DS 80 is the long-life choice.Saudi cement operators at Southern Province Cement and Yanbu Cement use N-EUPEX DS 80 on kiln drive auxiliary systems and preheater fan drives where maintenance windows are short and coupling failure is extremely costly.Product SpecificationsManufacturer: KTR (FLENDER brand). Torque: 500–1,000 Nm. Design: Double-segment pin and bushing. Hub: nodular cast iron. Bore range: 25–80mm. Max speed: 4,000 RPM.Frequently Asked QuestionsQ1: The double-segment pin provides 2x the pin count, doubling torque capacity and extending fatigue life. For cement kiln drives, this means 5+ year coupling life vs. 18 months for standard pins.Q2: Yes — pin bushing replacement takes under 30 minutes with the coupling installed.
