Torsionally rigid couplings
FLENDER brand torsionally rigid couplings provide backlash-free, efficient torque transmission while compensating for small radial and angular shaft misalignments.
Precision couplings
Essential for applications requiring accurate torque transmission, especially in harsh industrial environments. They are ideal for machine drive systems such as mills, conveyor belts and hoists, where minimising backlash is key to maintaining efficiency and reducing downtime.

Performance |
the N-ARPEX provides an optimum price/performance ratio, continuing the success of the ARPEX series |
|
Higher productivity, lower costs |
N-ARPEX provides lower operating costs |
|
Low bearing loads |
the coupling’s lightweight design reduces bearing loads, which contributes to longer component life |
|
Offset compensation |
high capacity to compensate for offsets of up to 1° |
|
Optimising storage costs |
combining the ARPEX ARS, ARC and ARP series into one N-ARPEX ARN series reduces the number of couplings, making selection easier and reducing storage costs |
