Rigid Couplings suit motion control applications.
Offered in aluminum, black oxide carbon steel, and stainless steel, 1- and 2-piece Rigid Couplings come in straight and step bore combinations to fit shaft sizes from 1/8-2 in. and 3-50 mm. Featuring precision-honed bores, couplings are torsionally rigid with virtually zero windup under torque loads, but are also rigid under loads caused by misalignment. Screws have Nypatch treatment to prevent...

Plastic Shaft Collars suit wash-down environments.
Made of acetal with stainless steel hardware for food processing environments, collars are offered in 1- and 2-piece clamp-style designs as well as set screw style. Clamp-style collars will not mar shaft, and design wraps around shaft for optimal holding power. Featuring forged socket hardware, products are single point faced to ensure perpendicularity and proper alignment. Bore sizes range from...

Miniature Couplings are suited for micro applications.
Available in aluminum or stainless steel, single-piece beam couplings feature multiple spiral cuts to accommodate angular and parallel misalignment as well as axial motion. They come in 20 sizes with ODs as small as 3/8 in. and bores as small as 3/32 in. Offered in 7 sizes of set screw or clamp style hubs, Oldham couplings are comprised of 2 aluminum hubs with drive tenons that mate with floating...

Beam Couplings are offered in 303 stainless steel.
Flexbeam couplings are one-piece components that incorporate spiral cuts to accommodate angular misalignment, parallel misalignment, and axial motion. Single-piece design and cut pattern ensure zero backlash and minimal wind-up. Flexbeam-2 and -3 couplings incorporate 2 sets of 2 spiral cuts; latter suits light-duty power transmission applications. Couplings are offered in 20 body sizes with ODs...

Oldham Couplings operate with zero backlash.
Featuring balanced design for reduced vibration, Paradrive oldham couplings are comprised of 2 hubs and acetal or nylon floating center disk. Torque transmission is accomplished by mating slots in center disk with drive tenons on hubs; slots fit with slight press. Disks are electrically isolating and can act as mechanical fuses. Couplings are offered in 7 sizes of set screw or Nomar clamp style...
