[Features]
· Since the NB slide bushing uses a round shaft as a guide, space can be used efficiently, making it suitable for compact mechanism designs.
· NB Slide Bushings are available in standard and corrosion-resistant specifications. In addition, retainers are standardized in both steel, which is highly resistant to harsh conditions, and resin, which offers low noise and cost-effectiveness, allowing you to select the optimal combination according to your usage conditions.
· NB slide bushings offer complete compatibility and can be used interchangeably with shafts in random combinations.
· Available in a wide variety of flange types, including the double square flange type
· The outer housing and flange are integrated, making installation easy
[Applications]
· Because linear motion with low friction can be achieved with a simple mechanism, they are used in a wide range of applications such as transfer equipment, food machinery, and semiconductor manufacturing equipment.
