1 1 4 Female Thread Rod End Swivel Ball Joint Bearing assy for Profile Cutting Machine. The ball joint bearing assembly consists of a housing with an internal threaded bore and an inner ball or spherical surface.
1.High positioning accuracy, high repeatability of Female rod end ball joints
The Female rod end ball joints is a design of rolling motion with a low friction coeffi cient, and the difference between dynamic and static friction is very small.
2.Low frictional resistance, high precision of swivel ball joint rod end maintained for long period
With a swivel ball joint rod end, a well lubrication can be easily achieved by supplying grease through the grease nipple on carriage or utilizing a centralized oil pumping system, thus the frictional resistance is decreased and the accuracy of swivel ball joint rod end could be maintained for long period.
3. Female rod end bearing is suitable for high speed operation
Due to the characteristic of low frictional resistance of female rod end bearing, the required driving force is much lower than in other systems, thus the power consumption of female rod end bearing is small.
4.Easy installation with interchangeability of female rod end bearing
Compared with the high-skill required scrapping process of conventional slide guide, the ball joint bearing can offer high precision even if the mounting surface is machined by milling or grinding.
1 1 4 rod ends is a high-precision ball joint bearing for joint and motion control. 1 1 4 rod ends are commonly used in mechanical systems requiring multidirectional motion and angular adjustment. The ball joint bearing can withstand high loads in radial and axial directions. 1 1 4 rod ends have flexible rotation and oscillation ability. And 1 1 4 rod ends are widely used in industrial machinery, automotive suspension systems and hydraulic equipment.
1 1 4 rod ends refer to bearings with a 1 1/4 inch thread diameter for applications requiring high strength and large load carrying capacity. The larger thread size of 1 1 4 rod ends provide a stronger mechanical connection, ensuring a stable and secure connection between the bearing and other mechanical components under heavy loads. Female rod end bearing is widely used in demanding mechanical systems, such as heavy equipment, hydraulic cylinders, and industrial arms.
The swivel and oscillating function of the swivel ball joint rod end provides flexible directional adjustment and angular compensation in complex movements. This enables 1 1 4 rod ends to cushion vibrations, absorb shocks and maintain system stability when used in dynamic mechanical systems. Whether it is a rotating arm in an industrial machine or a transmission in a hydraulic system, this 1 1 4 rod ends can significantly improve the efficiency and durability of the equipment.
1 1 4 rod ends and swivel ball joint rod end are premium quality ball joint bearing that combines high load carrying capacity with flexible swivel and angular adjustment. 1 1 4 rod ends' internal threaded design allows for easy mounting and dismounting, making 1 1 4 rod ends particularly suitable for industrial applications where high loads and high precision are required. The flexibility and durability of the ball joint bearing ensures stable operation under various complex working conditions and 1 1 4 rod ends is a key component in industrial equipment and mechanical systems.

Load capacity is determined by dynamic (C) and static (C₀) load ratings. For example: A 6205 deep groove ball bearing has a dynamic load rating of 14 kN, suitable for small motors. For heavy loads, choose tapered roller bearings (e.g., 32208 with C=90 kN). Recommendation: Share your equipment’s load analysis for optimal bearing selection.
Materials: Stainless steel (440C/316) or coatings (nickel plating, DLC). Seals: Double rubber seals (2RS) or PTFE seals. Example: Seawater pumps often use 316 stainless steel bearings with lifelong grease.
Speed limits depend on bearing type and lubrication: Standard 608ZZ ball bearings: ~18,000 rpm. Hybrid ceramic bearings (Si3N4 balls): 30–50% higher speeds. Solution: For high-speed applications, opt for oil lubrication or low-friction design.
Theoretical lifespan: Based on load calculations (see Q1). Real-world factors: Lubrication intervals (e.g., grease replenishment every 100km). Mounting surface flatness (≤0.01mm/m required). Tool: Free lifespan calculation software available.
Must-check: Slider hole spacing (e.g., 45mm×45mm). Rail width (15/20/25mm, etc.). Slider height (impacts machine space). Pro tip: Old slider model numbers are often engraved on the side.
Of course, we provide customized service, including add customers’ logo on the products, customized size of linear guide rail.
