Many maintenance teams face the same frustration: bearings in hydraulic cylinders or construction machinery failing prematurely due to misalignment or poor lubrication. Sourcing the right replacement often means navigating disjointed supplier networks, especially when dealing with mixed brand requirements. This is where a reliable rod end bearing that balances performance and availability becomes critical.
The POS22 self-aligning rod end bearing addresses these challenges with its self-lubricating design, eliminating the need for frequent grease injections in hard-to-reach locations. Our ISO 9001-certified production ensures consistent quality, while our extensive network covers both自有 brand and international standard bearings—meaning you can source this 22mm bore rod end alongside other required models from a single supplier.
This radial spherical plain bearing excels in applications with oscillating motion and moderate misalignment, such as engineering hydraulic cylinders and construction machinery articulation points. With a dynamic load capacity of 37400 N and static load capacity of 41700 N, it reliably handles the radial and axial forces common in forging machines and automation equipment, even under continuous operation.
The POS22’s bearing steel construction provides the hardness needed to resist wear in high-stress environments, while the whole outer ring design enhances structural integrity during shock loads. Its M22*1.5 thread size ensures compatibility with standard hydraulic cylinder rod ends, simplifying replacement. The self-lubricating sliding contact reduces friction coefficients, extending maintenance intervals compared to traditional greased bearings. At 28mm thickness and 0.435kg weight, it offers a compact, lightweight solution without compromising load capacity.
Choosing a bearing that matches both load requirements and maintenance capabilities directly impacts equipment uptime. A misselected rod end can lead to excessive vibration, accelerated wear on adjacent components, and unplanned shutdowns—costing far more than the initial bearing investment. The POS22’s precision dimensions (20*101*25mm specification) and self-aligning properties minimize installation errors, while its robust construction aligns with ISO 281 fatigue life standards, ensuring predictable performance in critical applications.
Our production process adheres to ISO 9001 standards, with raw material inspection and finished product testing for dimensions, hardness, and surface treatment. Every POS22 bearing comes with a质保期 against manufacturing defects, ensuring you receive a product that meets stated performance specifications. We maintain flexibility to supply bearings according to customer-specified standards, and our diverse sourcing network supports both standard and specialized requirements.
Whether you need a single replacement or bulk quantities of the POS22 self-aligning rod end bearing, provide your exact specifications and quantity, and we’ll deliver a competitive quote with lead time. Our team can also assist with cross-referencing other brands or models to ensure compatibility with your existing equipment.
Q: Do you supply bearings from other brands besides your own?
A: Yes, we support sourcing across all major international and domestic brands. Simply provide the required model or specifications, and we’ll handle procurement according to your preferences.
Q: How can I confirm if the POS22 is compatible with my equipment?
A: Share your equipment’s bearing dimensions (inner diameter, outer diameter, width), thread size, and load requirements. Our technical team will verify compatibility against your application needs.
Q: What is the warranty period for the POS22 bearing?
A: We provide a质保期 covering manufacturing defects. Specific terms are detailed in our sales contract, with replacement or refund available for products failing under normal operating conditions.
Q: What is the minimum order quantity for this bearing?
A: We offer low minimum order quantities, including single-unit purchases, to support both maintenance needs and small-batch production.
Q: How quickly can you ship the POS22 bearing after order placement?
A: For in-stock items, we dispatch within 1-2 business days. Shipping time depends on the selected method—express courier typically takes 3-5 days, while air or sea freight varies by destination.
Q: Can you produce custom rod end bearings according to specific drawings?
A: Yes, we support OEM/ODM customization. Provide your technical drawings or modified specifications, and we’ll evaluate production feasibility and lead time.
