CL99QD - Single Cartridge Seal -

The patented cartridge design features innovative dropproof springs, thereby speeding installation and maintenance.
Lightweight and balanced construction for optimal performance.
Self-aligning compensates for shaft runout up to ±0.8 mm, increasing operational reliability.
Stationary and divorced from the process media, the springs have prolonged service life.
Our jumbo coil springs have better wear resistance than many other brands.
All applied O-rings are micro-polished to ensure smooth and anti-stick surfaces.
Monolithic sealing faces with precise dimensions and excellent resistance to wear.
The CarLife family shares the major parts.
