Tag Archives: Farm PTO uni joints

PTO couplings are all universal joint based, which means constant greasing and replacing of worn bearings. Farming is tough on universal joints, Mud, dust, water and debris all cause contamination of the bearings. Agriculture U joints range in sizes up to Category 6. Twin Spring Coupling range offers both PTO couplings (Z6, Z20,Z21 teeth) 1 3/8″ and 1 3/4″ shaft size.

No internal components to maintain or replace, a one piece design means a longer lasting coupling

Cardan Joints or Universal joints, how about something better

Cardan Joints or Hooke joints? The Cardan joint was invented by Gerolamo Cardano in the 15th century, or at least the gimbal mountings that a modern day Universal joint contains. The Cardan joint gimbals are what we see today in the cross or bearings cross of a universal joint, the actual universal joints themselves were […]

Weasler PTO couplings – Replace them with a maintenance free alternative

Weasler PTO couplings Weasler PTO couplings are a brand well known in the agriculture u-joints, Walterscheid and Bondioli as well . They all rely on the underlying universal joint technology to work. The only real difference is the Weasler PTO couplings are made using larger uni joints, revolving around technology like the Spicer 1310/ Spicer […]
