Specifications/Overview

■Features of dust seal type and non-contact seal type
·Dust seal type has built-in contact seals which prevent small dust from entering sliding contact surface.
·For sliding resistance of dust seal type, refer to sliding resistance test data.
·Non-contact seal type prevents large size dust entry.
Clearance between shafts and bushings (approximately 0.1 mm) lowers the sliding resistance than dust seal type.
