An integral part of many Hilliard motion control products is their roller-ramp design. The use of hardened cams and precision-machined rollers, and outer member maximizes service life. There is almost no wear during free wheeling operations because rollers are free to rotate between the outer member and inner cam. When the rollers are engaged, the load falls at random positions on the rollers. the result is superior service life and reliability. The MTR is similar to the MT design except...

The Lechler Ramp Bottom Hollow Cone spray nozzle creates as fine a spray (i.e., the smallest droplets) for given flow rates as is possible without the use of compressed air. This nozzle gets its name from its unique design which contains a ramp in the bottom of the internal chamber which projects the fluid into a swirl chamber from which it exits the nozzle orifice. The resulting spray is uniform in distribution with the smallest droplets possible for its flow rate and without using compressed... (read more)Browse Nozzles Datasheets for Lechler, Inc. -
Superior strength, impact, and vibration resistance facilitate smooth vehicle loading.
