XL2 Straight-Bore Jaw Flexible Coupling, for Pumps and General Industrial Transmission

The FLC XL2 jaw coupling uses a classic straight-bore design made up of two metal jaw hubs and a polyurethane (PU) spider elastomer. Compact and maintenance-free, it is built for general industrial transmission at medium speed, medium torque, and with frequent starts and stops, and is a highly cost-effective power connection solution.

Item Specification
Model XL2FLC jaw coupling
Type Straight-bore jaw flexible coupling
Body material Cast iron / aluminum alloy / 45# steel optional
Surface treatment Black phosphating, black oxide
Elastomer material Polyurethane spider (wear-resistant, oil-resistant, anti-aging)
Function Compensates axial, radial, and angular misalignment; damps vibration and cushions shock
Suitable conditions Medium speed, medium torque, equipment with frequent starts/stops and forward/reverse operation
Machining Custom bores and keyways; laser marking of customer LOGO supported
Packaging Export solid-wood crate; neutral packing and customer shipping marks available

1. Excellent vibration damping and cushioning: The polyurethane spider sits between the jaws, not only transmitting torque but also effectively absorbing vibration and shock loads during operation, protecting the motor and driven machinery and greatly lowering the failure rate of the whole machine.
2. Strong misalignment compensation: Allows relatively large axial, radial, and angular installation misalignment, greatly relaxing the demanding alignment accuracy required at installation and making on-site assembly more efficient.
3. Insulating and maintenance-free design: The elastomer is electrically insulating, effectively blocking shaft currents from damaging bearings through electrical erosion. No lubricating oil is needed, and daily maintenance only requires checking the condition of the spider, saving time and effort.
4. Flexible materials, strong adaptability: The body is available in cast iron, aluminum alloy, or 45# steel. Aluminum alloy suits lightweight, high-speed needs, while cast iron/steel meets heavy-load, shock-resistant needs; custom non-standard bores and keyways are supported.

A cushioning tool for "frequent start-stop conditions": The wear-resistant, aging-resistant PU spider resists deformation under alternating forward/reverse and frequent starts and stops, with a life far exceeding ordinary rubber blocks.
A cost-effective universal replacement part: Standard straight-bore sizes cover a wide range and are well stocked, making it the first choice for pump and fan repair and replacement.

Pumps and fans: Drives of all kinds of centrifugal pumps, water pumps, and small ventilators.
Light industry and packaging: Packaging machinery, dyeing equipment, and assembly-line conveying mechanisms.
Automation: Auxiliary axes of CNC machine tools and input ends of small-to-medium gear reducers.
