Finding the right needle roller bearings for heavy machinery often means sifting through dozens of models, checking dimensions against worn parts, and worrying if the materials will hold up under load. Many buyers face delays when suppliers don’t stock the exact size, or end up with bearings that fail prematurely due to substandard steel or poor cage design.
Our BDL Needle Roller Bearings NA4822, NA4824, and NA4826 address these challenges with ISO 9001-certified manufacturing processes and a focus on critical performance features. Designed for medium to large applications (120-190mm outer dimension), these bearings combine bearing steel construction with precision-machined steel or brass cages to handle radial loads in industrial settings like hydraulic systems and conveyor equipment. With both OEM and ODM services available, we can match your exact specifications, whether you need standard sizes or custom solutions.
These needle roller bearings excel in applications where space is limited but load capacity is critical. The single-row design and separated structure allow for easy installation and maintenance, while the radial load orientation makes them ideal for rotating components in engineering machinery and mining equipment. Operating within typical industrial temperature ranges, they maintain consistent performance in dusty, high-vibration environments—common pain points where lesser bearings fail.
The bearing steel material provides the hardness (typically 58-62 HRC) needed to resist wear under heavy loads, ensuring a longer service life compared to softer alloys. The choice between steel and brass cages offers flexibility: steel cages handle higher temperatures and shock loads, while brass cages reduce friction and are better suited for high-speed applications. The precise 100*210*67 mm specification (for model 29420) ensures compatibility with international standards, making replacement straightforward without reworking adjacent components. Additionally, the separated design allows for quick disassembly during maintenance, reducing downtime in critical operations.
Investing in quality needle roller bearings like these BDL models reduces long-term costs by minimizing premature failures. A bearing with subpar material or imprecise dimensions can cause shaft wear, misalignment, and even damage to connected parts—leading to unplanned downtime and expensive repairs. By contrast, these bearings meet strict dimensional and hardness standards, supporting reliable operation that aligns with ISO 281 fatigue life calculations. When multiplied across multiple machines, the savings from reduced maintenance and longer service intervals far outweigh the initial investment.
Every BDL needle roller bearing undergoes comprehensive quality checks, from raw material inspection to final dimensional and hardness testing. Our ISO 9001 certification ensures consistent production processes, and we stand behind our products with a warranty against manufacturing defects. Whether you need the NA4822, NA4824, NA4826, or other models, we source from established production lines and can provide test reports upon request. With a focus on transparency and reliability, we help you avoid the risks of counterfeit or substandard bearings.
Whether you need NA4822, NA4824, NA4826, or custom-sized needle roller bearings, we can provide competitive pricing and fast lead times. Simply share the model number, dimensions, and quantity, and our team will confirm availability or assist with specifications. The sooner you order, the sooner we can ship—keeping your machinery running with minimal disruption.
Q: Do you supply bearings from other brands besides BDL?
A: Yes, we offer a full range of bearing brands, including international and domestic options. We can source specific models as per your requirements.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment’s make, model, or the bearing dimensions (bore, outer diameter, width), and our technical team will verify compatibility.
Q: What is your warranty policy?
A: We provide a warranty against manufacturing defects. The specific terms are outlined in our sales contract, typically covering material and workmanship issues.
Q: What is the minimum order quantity?
A: We accept low minimum orders, making it easy to source small quantities for repairs or larger volumes for production.
Q: How long does shipping take?
A: In-stock items ship within 1-3 business days. Shipping time depends on the method: courier (3-7 days), air freight (5-10 days), or sea freight (20-40 days).
