CPWD Series High-Speed Precision Aluminum Universal Joint – Single/Double/Telescopic with Needle Bearings

Factory direct | High-strength aluminum alloy | Needle roller bearings – 4000 RPM | 45° operating angle per joint | Low backlash | Anodized finish | Clamping screw fastening | OEM/ODM/OBM

The Apexcoupling CPWD series is a high-speed precision universal joint engineered for demanding power transmission applications where lightweight construction, high rotational speed, and angular flexibility are critical. Available in single joint (CPWG), double joint (CPWX), and telescopic (CPWS) configurations, this coupling features precision needle roller bearings that enable smooth operation at speeds up to 4000 RPM – significantly outperforming sliding bearing designs [0†L10][3†L15-L16]. Constructed from high-strength aluminum alloy with an anodized surface treatment, it offers excellent strength-to-weight ratio, corrosion resistance, and durability. With 45° angular compensation per joint, low backlash for precise positioning, and clamping screw fastening for secure shaft attachment, the CPWD series is the ideal solution for packaging machinery, printing equipment, robotics, CNC machines, semiconductor manufacturing, and high-speed automation.

✅ Needle bearing design – up to 4000 RPM, low friction, maintenance-free. Lightweight aluminum construction – high strength-to-weight ratio. Single, double, or telescopic – choose your configuration. 45° angle per joint – large angular compensation.

Why Choose Apex Coupling for CPWD Universal Joints?

FAQ

Q: What is the maximum speed of the CPWD series?
A: With needle roller bearings, the CPWD series can operate at speeds up to 4000 RPM [0†L5][3†L15-L16]. This is significantly higher than sliding bearing designs (1000 RPM) [0†L10].

Q: What is the difference between CPWG, CPWX, and CPWS?
A: CPWG is a single joint for angular misalignment only. CPWX is a double joint for both angular and parallel offset. CPWS is a telescopic (sliding) type that allows axial length adjustment.

Q: What is the maximum operating angle?
A: Each joint can operate at angles up to 45° [0†L12]. For double joint (CPWX), total articulation can reach 90°.

Q: What materials are used?
A: The body is made of high-strength aluminum alloy with an anodized surface treatment for corrosion resistance and durability.

Q: What type of bearings are used?
A: The CPWD series uses needle roller bearings – providing high dynamic load capacity, low friction, and maintenance-free operation [0†L7-L8][3†L40-L41].

Q: Is the coupling maintenance-free?
A: Yes. The needle bearings are sealed and lubricated for life – no regular maintenance required [3†L40-L41].

Q: Does the coupling have backlash?
A: The CPWD series features low backlash due to the precision needle bearing design – ensuring accurate positioning for automation and robotics applications [2†L9].

Q: Can I get a custom coupling?
A: Yes. We offer OEM, ODM, and OBM support – custom bores, finishes, and configurations available.

Q: What industries is this coupling suitable for?
A: Packaging machinery, printing equipment, robotics, CNC machines, semiconductor manufacturing, food & beverage, and general automation.
