Needle bearing universal joints feature high-quality needle-roller bearings, precision-machined trunnions with hardened and ground journals, and the option of alloy or stainless-steel yokes to minimize friction and enhance performance in applications demanding precision and prolonged durability.
These needle bearings come pre-lubricated and necessitate no maintenance, effectively minimizing machine downtime and extending the service life. The majority of u-joints are equipped with dust seals for the bearings.
Customizable bores are available for blind configurations, preventing shaft penetration into the central joint components and delivering extra protection against contamination.
Needle-bearing universal joints from Runsom Precision are ideal for applications necessitating elevated speeds, low-to-moderate loads, and extended service life in industries like medical, packaging, and robotics.
Runsom Precision innovative ‘hybrid’ pin and block type needle-bearing design merges the superior torque capacity of friction-bearing (pin and block) joints with the needle-bearing’s capability to function continuously at higher speeds with minimal wear and reduced backlash. This design is more suitable for accommodating high side-loads and operating angles.
Our needle-bearing universal joints are offered in outer diameter sizes ranging from 3/4” to 2” with plain bore or bore with keyway options available in sizes from 3/8” to 1” or 8mm to 25mm. All bore types can be equipped with a single set screw.
Customization for Needle Bearing Universal Joints
The customization of universal joints can encompass various aspects such as bores, keyways, and special hub configurations. These joints can be crafted from a diverse range of materials and can be finished with specialized coatings and platings.
Additionally, components can be equipped with lubricant-retaining boots that house specialty lubricants tailored to a variety of industries and applications.
Upon request, special materials, machining options, coatings and platings, lubricant retaining boot covers, and other customizations are available.
