What is a Universal Joint (U-Joint)?
A universal joint, also known as a U-joint, is a mechanical component used to connect two
shafts at an angle to transmit rotational motion. It allows for the transmission of torque
and rotational movement between shafts that are not in a straight line and may be offset or
angled relative to each other.
According to wikipedia, A universal joint (also called a universal coupling or U-joint) is a joint or coupling connecting rigid shafts whose axes are inclined to each other.
Structure and Function:
- Cross-Shaped Design: The basic design of a universal joint consists of a cross-shaped yoke
with four arms. Each pair of arms is connected to the ends of two shafts that intersect at an
angle.
-
Bearings: At the ends of each arm of the yoke, there are needle bearings or bushings that
allow the joint to pivot smoothly and transmit torque.
-
Cross-Coupling: The center of the cross-shaped yoke contains a mechanism (often a spherical
bearing or trunnion) that allows the joint to accommodate angular misalignment between the
connected shafts.

6. How do I know when to replace a universal joint?
Look for vibration, clicking noises, or visible wear on cross bearings. Our joints include zerk fittings for easy maintenance.
7. Can you make u-joints with metric/imperial hybrids?
Yes! We specialize in custom hybrid universal joints for international equipment compatibility.
8. How often should I grease universal joints?
For needle-bearing U-joints:
- ● Normal use: Every 500 operating hours
- ● Harsh conditions (dust/water): Every 200 hours
9. What’s the max operating angle for a U-joint?
Standard joints work at ≤15°. For 15°–45° angles, use high-angle joints with special bearings.
10. Can I replace just the cross bearing?
Yes! We sell cross & bearing kits for common sizes (e.g., 1-inch bore, Series 5).
11. Why is my U-joint vibrating at high RPM?
Likely due to:
- ● Imbalance (Use dynamically balanced joints)
- ● Worn bearings (Inspect for pitting/spalling)
- ● Misaligned yokes (Laser-align shafts)
12. Do you make metric-to-imperial hybrid U-joints?
Yes! Example: 20mm bore (metric) with 3/4" keyway (imperial).
