BF1 Series 10-28mm Aluminum Alloy Full Encoder Coupling - OD55mm* L78mm

With one hole diameter measuring 10mm and the opposite hole diameter measuring 28mm, this full encoder coupling is the reliable and economic solution for the connection of shafts, allowing for the transmission of power. This critical connector piece features a durable aluminum construction offering resistance to wear and tear and reliable, long-term performance. This particular coupling features an outer diameter of 55mm and a length of 78mm.


Fail-safe — will still perform if elastomer fails

No metal to metal contact

Resistant to oil, dirt, sand, moisture and grease

More than 850,000 combinations of bore sizes

Most types available from stock in 24 hours

The Jaw Type couplings from YUMO are offered in the industry’s largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications.


Include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers, and conveyors.YUMO’s Jaw Type couplings are available in 24 sizes from a minimum torque rating of 3.5 in–lbs (0.4 Nm) to a maximum torque rating of 170,004 in–lbs (19209 Nm) and a bore range of .125 inches (4.45mm) to 7 inches (178mm). Lovejoy’s standard bore program covers AGMA, SAE, and DIN bore/keyway and spline bore combinations.

YUMO Jaw Type couplings generally consist of two hubs (available in sintered metal, aluminum, bronze, steel, stainless steel, and ductile iron), and an elastomer element, known as a spider or cushion (materials available include NBR SOX rubber, Urethane, Hytrel, and Bronze).
