Pin-and-Block Joint |
A good choice when you need accurate and repeatable motion, these U-joints have zero backlash (no play), so there’s no motion lost when your shafts change direction. This keeps machines running smoothly. They’re single U-joints, so they connect and transfer torque between shafts that are misaligned at an angle.
Your shafts’ misalignment will affect the speed and torque the U-joint will be able to transmit. The more the shafts are misaligned, the less speed and torque the U-joint will be able to transmit.
Pin-and-Block Joint—Pin-and-block U-joints work well in most applications since they handle higher torque at lower speeds than joints with ball bearings.
Acetal—Acetal U-joints weigh less than metal U-joints. They protect components in your system from stray electrical currents by blocking the flow of electricity between your shafts.
Set-Screw Shaft Mount—U-joints that connect with set screws don’t require you to drill any holes.
Lubrication Not Required—U-joints that don’t require lubrication are often used with optical devices and other sensitive equipment because they're less likely to attract dust and debris compared to lubricated U-joints. They’re also easier to maintain.
