The Non-telescopic Universal Joint is a pure angle compensation transmission component that is distinct from telescopic universal joints. It has no axial extension function and is specifically designed to solve the problems of misalignment of two shafts and non-coaxial transmission in equipment. As a core basic component of the mechanical transmission system, this product relies on a precise hinge structure to achieve stable and efficient power transmission in equipment with fixed installation spacing and no need for axial displacement adjustment.
Our factory offers a complete range of products, covering single-section, double-section, and quick-release locking structures, as well as two configurations of sliding bearings and needle bearings, corresponding to different upper speed limits. It can be adapted to a maximum speed of 4000 r/min for high-speed operations. At the same time, it supports various high-precision shaft hole customizations, making it the preferred transmission component for standardized general construction machinery.

- General construction machinery equipment: The non-telescopic universal joint can be compatible with various conventional construction machinery transmission systems and operates stably in conditions where the installation spacing is fixed and no axial displacement compensation is required.
- Medium and low-speed conventional transmission equipment: The sliding bearing model is suitable for equipment with medium and low speeds within 1000 r/min, running smoothly, durable and suitable for long-term continuous conventional operations.
- High-speed precision transmission equipment: The needle roller bearing model can meet the requirements for high-speed operation of 4000 r/min, suitable for transmission scenarios of precision and high-speed automated equipment.
- Equipment requiring quick disassembly and assembly: The quick disassembly locking series is suitable for production lines and supporting equipment that require frequent maintenance and disassembly, effectively improving maintenance efficiency.
Q1: Can the fixed universal joint compensate for axial displacement?
A1: The Non-telescopic universal joint is a non-extendable fixed structure. It only supports angle deviation compensation and has no axial extension function. It is only applicable to working conditions where the equipment's axle spacing is fixed and there is no axial movement.
Q2: How to select the type of sliding bearings and needle roller bearings?
A2: For medium and low-speed applications with normal load conditions within 1000 r/min, choose the G, GD, and GR types of sliding bearings; for high-speed transmission scenarios within the range of 1000 - 4000 r/min, preferentially select the GZ, GDZ, and HR types of needle roller bearings.
Q3: Does the quick-release universal joint support customization of any hole type?
A3: It does not support non-standard customization. The quick-release structure is only compatible with H7 standard holes, DIN standard flat key slots or hexagonal holes, ensuring locking accuracy and structural stability.
Q4: How can we distinguish between single-joint and double-joint universal joints based on their application scenarios?
A4: The single-joint design is compact and suitable for small-angle offset conditions; the double-joint can accommodate larger overall angle deviations and is suitable for complex space transmission layouts.
As a local origin factory in China, Jiteng independently completes the precision processing, assembly and inspection of Non-telescopic universal joints, strictly following industrial standards to ensure the quality and stability of the products.
- Full range of models: The factory always has multiple series of models in stock, including high and low speed, single and double sections, and quick disassembly models. There is no need for external procurement, and all transmission components can be fully equipped in one step.
- High precision customization capability: Supports H7 precision holes, national standard keyways, and special holes customization. The processing tolerances are strictly controlled, making the products highly interchangeable and with high installation compatibility.
- Strict verification of working conditions parameters: Each unit is inspected one by one for speed limits, hinge angles, and fit accuracy to ensure stable operation under both high and low speed conditions, without jitter or abnormal wear.
- Professional selection and delivery services: Can precisely match models based on the customer's equipment speed, angle, and installation method. Common models are available for direct shipment, and non-standard specifications can be quickly customized and delivered.
