Crossed roller bearings
with ground raceways
Type LEW

Product image Crossed roller bearings with ground raceways Type LEW

Description

Franke bearing elements type LEW are suitable for medium rotational speeds and accuracies. They convince by smooth running even under tilt moment loads, high rigidity and compact installation space. The crosswise arranged rollers can support high loads from all directions. Bearing elements of model LEW are insensitive to shock and vibration. They offer the greatest possible flexibility in terms of preload, running characteristics and diameter ranges.
