NBK MOS/MOS-C

Specifications Catalog Number Max.Bore(mm) Rated Torque […]

Small Eccentric Reaction Force
Allowable Misalignment
Vibration Absorption
Oldham type flexible coupling
Compact coupling with short overall length
Slippage between hubs and spacer allows high parallel and angular misalignments
Minimized load on shaft caused by misalignments.
Simple configuration enables ease of assembly
Protruded spacer design enables high allowable angular misalignment
Exhibits excellent electrical insulation
Operational Temperature: -20℃~80℃
Finished products featuring two different end bore diameters available in stock
Oldham coupling with no protrusions feature low allowable misalignment (1〜1.5°) due to interference between the spacer and hubs at the proximity of the outside diameter.
A bending moment is generated as well.
The MOS series features a high maximum angular misalignment (3°), enabled by the protrusions which act as points of support.
No bending moment is generated and the shaft load is minimized.
