Finding the right bearing for mining and agricultural machines often means wading through countless models, dealing with mismatched dimensions, or settling for low-quality options that fail prematurely. When equipment downtime costs hours of productivity, choosing a reliable bearing that fits your exact specifications isn’t just a purchase—it’s a critical operational decision.
This self-aligning spherical roller bearing is engineered to address the challenges of heavy-duty applications like mining and agriculture. With interchangeable dimensions following international standards (DIN, ISO, JIS), it eliminates the hassle of cross-referencing complex model systems. Our ISO 9001-certified production process ensures each unit meets strict quality benchmarks, from raw material inspection to final hardness testing. Whether you need a single replacement or bulk orders, our现货库存 (ready stock) allows for quick fulfillment, reducing machine idle time.
Designed to handle radial loads with a contact angle of 0°, this bearing excels in scenarios where shafts may experience minor misalignment—a common issue in agricultural tillers or mining conveyors. The non-aligning design maintains stability under variable loads, while the choice of seals (Zz, 2RS, Open) lets you tailor protection to your environment, from dusty fields to wet mining sites. With vibration ratings up to Z3V3, it minimizes operational noise and extends equipment lifespan.
The bearing’s construction from high-grade bearing steel ensures surface hardness and wear resistance critical for heavy machinery. Precision ratings from P0 to P2 allow you to balance performance needs with budget—P5 or P4 grades for high-speed applications, P0 for general use. The unseparated design simplifies installation, while lubrication flexibility (grease or oil) lets you adapt to maintenance schedules. At 0.65 kg, it offers a lightweight solution without compromising load capacity, making it ideal for mobile agricultural equipment.
Opting for a precision-engineered bearing like this model reduces hidden costs associated with frequent replacements. Poorly made bearings often fail due to material fatigue or imprecise dimensions, leading to unplanned downtime, repair labor, and potential damage to adjacent components. By adhering to ISO standards and undergoing rigorous testing (vibration, hardness, dimensional accuracy), this bearing delivers consistent performance, lowering long-term operational expenses. Choosing the correct seals and lubrication further extends service intervals, maximizing productivity.
Our commitment to quality starts with ISO 9001-certified manufacturing, ensuring every bearing meets global standards. Raw materials are inspected for purity and strength, while finished products undergo dimensional checks, hardness testing, and surface treatment evaluations. We stand behind our products with a warranty against manufacturing defects, providing peace of mind for critical applications. With access to both our own brand (BDL) and international brands, we can source or produce bearings to your exact specifications, whether you need OEM/ODM customization or standard models.
Whether you need the 21305 model or another specification, we can help. Provide your required model number, dimensions (d x D x B), and quantity, and our team will quickly confirm availability and pricing. With our extensive inventory and global sourcing network, we ensure you get the right bearing when you need it.
Q: Do you supply bearings from other brands or models?
A: Yes, we support inquiries for all bearing brands and models, and can supply according to your specified brand or technical requirements.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment’s required bearing dimensions (d, D, B) or original model number, and our technical team will verify compatibility.
Q: What is your warranty policy?
A: We offer a warranty against manufacturing defects; specific terms are detailed in each sales contract.
Q: What is the minimum order quantity?
A: We accept low minimum order quantities, including small trial orders for testing.
Q: How long does shipping take?
A: In-stock items ship immediately; delivery time depends on your location and chosen shipping method (courier, air, or sea).
Q: Do you offer OEM/ODM services?
A: Yes, we provide OEM/ODM customization based on your drawings or technical specifications.
