To help you understand PHS type rod end bearings more comprehensively and in depth, the following will elaborate on product definition, performance, specifications and other aspects combined with the above core points, clearly presenting the core value and application details of the product.

PHS series rod end bearings are female threaded, bushed, oil-lubricated spherical plain bearings, designed specifically for low-speed oscillation, angular deflection and compound load working conditions. They are widely used in connecting rod and control mechanisms of automation equipment, machine tools, construction machinery, textile and packaging equipment, and are core basic components for high-precision transmission and connection.

Product Definition and Structure

PHS is a female threaded rod end bearing (male threaded corresponds to POS series), adopting a classic three-piece structure: the rod end is forged from high-quality carbon steel with anti-rust treatment on the surface; the spherical inner ring is made of high-hardness bearing steel with mirror polishing; the inner bushing is made of wear-resistant copper alloy; the thread is standard metric female thread, with right-hand thread as the conventional type and left-hand thread marked with suffix "L" (e.g., PHS10L). The overall structure forms a steel-copper friction pair, which realizes long-term lubrication and stable operation with oil channels and grease nipples.

Core Performance Advantages

1. Strong Self-Aligning Capacity: The spherical sliding structure allows a large angular deflection, which can compensate for installation errors and misalignment, ensuring smooth operation of the mechanism.

2. Compound Load Bearing: It can bear radial load and bidirectional axial load simultaneously, with impact resistance and vibration resistance, achieving high load with small volume.

3. Wear Resistance and Long Service Life: The copper alloy bushing combined with the bearing steel spherical surface has low friction coefficient and little wear, suitable for frequent oscillation and intermittent movement.

4. Easy Installation and Maintenance: The female thread can be directly connected to lead screws, connecting rods and joints; models with grease nipples can be refueled online to extend service life.

5. Standardized Interchangeability: The dimensions comply with international general standards, which can be directly interchanged with the same model of mainstream brands, making selection and replacement more convenient.

Usage Notes

It is recommended to apply grease before installation; avoid exceeding the rated load and deflection angle; regular grease replenishment is recommended for heavy load/high frequency working conditions; special models such as left-hand thread, stainless steel and self-lubricating can be customized on demand.

Summary

PHS type rod end bearings take high rigidity, strong self-alignment, easy installation and long service life as their core advantages, and are a mature solution for solving oscillation, deflection and alignment compensation in industrial transmission. The standardized design, stable performance and wide adaptability make it a reliable choice for equipment connecting rod and control mechanisms.
