Pin & Block universal joints are simple, cost-efficient, and can carry high loads at low bearing speeds. However, pin joints tend to be more difficult to lubricate and heat generated by the friction can be a problem down the road due to wear or galling. If so, self-lubricating or porous & lube-soaked materials can be an effective option. Plain bearings can be adapted to the application by using materials such as alloys, stainless steel, or a combination of harder & softer materials like Brass, Bronze, or PTFE.
- Available design options are Heavy Duty, High Strength, Stainless Steel, Leveler Strength, Military Standard & Pin & Block Needle-Bearing
- Pin joints contain two yokes and the center block, secured with pins, snap rings or rivets (as shown in the first picture)
- Pin & Block Needle-Bearing joints feature roller bearings and bushings in the pin and block design (as shown in the second picture)
