Bellow couplings / grub screw / bellows: phosphor bronze / body: brass / NB / NIHON MINIATURE (Part Numbers - CAD Download)

Promotional pricing ends 30/11/2024

Low cost bellows coupling, using phosphor bronze for bellows, and brass for boss part. Nickel plating treatment.

[Features]
· NB series bellows coupling is made with phosphor bronze (PBP3-0), with brass bracket (BsBM) used, both fixed with solder.
· No backlash, low inertia, high torsional rigidity, compact coupling with flexibility.
· Model number is no. 4, with shaft diameter from 2 mm to 10 mm, and always in stock with all shaft diameter combinations (inner diameter tapping processed).
