Rigid coupling GN 2260

stainless steelsteelfor shafts

Product description
Rigid couplings GN 2260 connect supported shafts or are used as couplings for shaft extensions. They transmit angular positions and high torques precisely and with zero backlash, without compensating for alignment errors and runout tolerances. The slotted design makes installation quick and straightforward.

Installation notes
With bore code K the keyway is integrated into both bores d2 and d3. For applications subject to strong vibrations, use thread locking on the clamping screws is recommended.

Specification

• Coupling materials and finishes: Steel — designation ST — blackened; Stainless steel — designation NI — AISI 303, plain finish
• Socket cap screws: ISO 4762 — steel, blackened for ST; stainless steel for NI
• Operating temperature range: -40 °C to +175 °C
• RoHS: Yes
