New Energy Compressor – Composite Bearing with a Pin Shaft

Features: Designed for the rod‑end of piston compressors; compared with crankshaft bearings, the load at this location is relatively lower. However, due to space constraints, the bearing size cannot be excessively large, and axial positioning is required. In early multi‑cylinder engines, customers typically opted for either deep‑groove ball bearings or full‑complement needle roller bearings, but both approaches presented certain drawbacks. Deep‑groove ball bearings are larger in size yet offer limited load capacity, while needle roller bearings lack reliable axial retention and struggle to maintain effective grease lubrication. Our company employs a composite rod‑end bearing with a pin, featuring two structural designs: thickened inner and outer rings, an enlarged inner raceway diameter, and a widened interference fit on the axial retaining snap ring. This configuration ensures smoother operation under impact loads and prevents axial movement that could lead to frame distortion. Regarding the cage, it undergoes special treatment to achieve superior wear resistance, while maintaining adequate plasticity and rigidity in the core, thereby enhancing impact‑resistance. Alternatively, high‑performance polymer composites may be used to reduce weight and improve operational stability, facilitating oil‑film formation. For lubrication, we utilize German‑imported high‑temperature grease containing nano‑scale solid additive particles, making it well suited for high‑temperature, heavy‑load, and fretting‑wear conditions. This product can also be applied in electric vehicles, gearboxes, and other industries.

Product Description

Composite bearing with a shaft pin for new-energy compressors

Features: Applied to the rod‑end of piston compressors; compared with the crankshaft bearing, the load at this location is relatively modest. However, due to space constraints, the bearing size cannot be excessive, and axial positioning is required. In early multi‑cylinder machines, customers considered two bearing arrangements—deep‑groove ball bearings and full‑complement needle roller bearings—but both presented certain challenges. Deep‑groove ball bearings are larger in size yet offer limited load capacity, while needle roller bearings cannot provide reliable axial locating and struggle to retain lubricant effectively. Our company employs a composite rod‑end bearing with a pin, featuring two structural variants: thickened inner and outer rings, an enlarged diameter of the inner raceway, and a widened interference fit on the axial retaining ring. This design ensures smoother operation under impact loads and prevents axial movement that could lead to frame distortion. Regarding the cage, it undergoes special treatment to achieve superior wear resistance, while maintaining adequate plasticity and rigidity in the core, thereby enhancing impact‑resistance. Alternatively, high‑performance polymer composites may be used to reduce weight and improve operational stability, facilitating oil‑film formation. For lubrication, we utilize German‑imported high‑temperature grease containing nano‑scale solid additives, ideally suited for high‑temperature, heavy‑load, and fretting‑wear conditions.

It can also be applied in industries such as electric vehicles and gear reducers.

Single-row deep groove ball bearing

It is the most typical structural form among rolling bearings and finds wide application. In addition to supporting radial loads, it can also accommodate axial loads in both directions. With a low friction torque, it is ideally suited for applications requiring high-speed rotation, low noise, and minimal vibration.

Angular contact ball bearing

They are primarily used in high-speed rotating applications with relatively light loads and can withstand combined radial and axial loads. When installed in pairs, angular contact ball bearings can handle combined radial and axial loads, with the radial component being dominant, and they can also accommodate purely radial loads. In a tandem arrangement, they can only support axial loads in one direction, whereas the other two arrangements can accommodate axial loads in either direction.

Cylindrical roller bearing

Cylindrical roller bearings are line-contact bearings. They offer high load-carrying capacity and primarily support radial loads. The rolling elements experience low friction against the raceway shoulders, making them well suited for high-speed operation. Depending on whether the rings are equipped with shoulders, they can be classified into single-row cylindrical roller bearings—such as NU, NJ, NUP, N, and NF—and double-row cylindrical roller bearings—such as NNU and NN.
