Finding the right cylindrical roller bearing for your equipment can be a hassle—mismatched dimensions lead to installation delays, while low-quality bearings cause premature wear and unexpected downtime. With so many brands and models on the market, coordinating multiple suppliers to compare availability and lead times only adds to the frustration.
Our cylindrical roller bearings, including models like 6305-2RS1, 6305-2RZ, and 6305-2Z, address these challenges head-on. Backed by ISO 9001-certified production processes and a comprehensive inventory of both自有品牌 and international brands like NTN, NSK, and Timken, we ensure you get the right bearing when you need it. Whether for automotive transmissions, industrial conveyor systems, or hydraulic pumps, these bearings are built to handle radial loads and high-speed operations with minimal maintenance.
Designed with precision tolerances (25x62x17mm specification), these cylindrical roller bearings excel in applications requiring smooth rotation under radial loads. The Z1V1 to Z3V3 vibration classes ensure stable operation, making them ideal for electric motors and automation equipment where vibration control is critical. Their versatile lubrication options—grease or oil—allow adaptation to operating temperatures and speeds, from moderate industrial settings to more demanding mechanical systems.
The 6305 series incorporates several critical design elements that enhance performance. The high-grade grease technology reduces friction and wear, extending service life even in hard-to-maintain locations. The double-sealed (2RS1, 2RZ) and double-shielded (2Z) variants provide protection against contaminants, making them suitable for dusty or moist environments. Additionally, the bearings’ surface hardness and precision machining ensure consistent load distribution, minimizing the risk of early failure due to misalignment or uneven stress.
Investing in quality cylindrical roller bearings reduces long-term expenses by minimizing downtime and replacement frequency. Inferior bearings often fail prematurely due to subpar materials or imprecise manufacturing, leading to unplanned maintenance and production losses. Our bearings, tested for dimensional accuracy and hardness, align with international standards to ensure compatibility and reliability. By selecting the correct model—whether 2RS1 for sealed applications or 2Z for high-speed scenarios—you avoid the hidden costs of frequent replacements and equipment damage.
Our commitment to quality starts with rigorous raw material inspection and extends through every stage of production. Each bearing undergoes dimensional, hardness, and surface treatment testing to meet industry standards. We offer a warranty against manufacturing defects, ensuring peace of mind with every purchase. With access to a wide range of brands and models, we can source or produce bearings to your exact specifications, whether standard or custom OEM/ODM designs. Our rich stock levels mean most orders ship within days, reducing lead times and keeping your operations running smoothly.
Whether you need the 6305 series or another cylindrical roller bearing model, we’re here to help. Provide us with your required model number, dimensions, and quantity, and our team will respond within 0.5 hours with pricing and delivery details. With our extensive brand coverage and technical expertise, we simplify the采购 process so you can focus on what matters—keeping your equipment operational.
Q: Do you supply bearings from other brands besides those listed?
A: Yes, we support procurement of all major international and domestic brands. Simply specify your desired brand and model, and we will source it for you.
Q: How can I confirm if the 6305 bearing fits my equipment?
A: Provide your equipment’s required bore diameter (d), outside diameter (D), and width (B), or the original bearing model. Our technical team will verify compatibility with the 6305 series specifications (25x62x17mm).
Q: What is your warranty policy for these bearings?
A: We offer a warranty against manufacturing defects. Specific terms are detailed in each order contract, and defective products can be replaced or refunded within the warranty period.
Q: What is the minimum order quantity for the 6305 series?
A: We accept low minimum order quantities, including small sample orders, to support your testing and prototyping needs before full-scale procurement.
Q: How quickly can you ship the 6305 bearings?
A: With rich stock availability, most orders ship within 1-3 business days. Shipping time depends on the selected method: Express (1-5 days), Air (3-7 days), or Sea (20-40 days).
Q: Can you produce custom bearings with OEM/ODM requirements?
A: Yes, we offer OEM and ODM services. Provide your technical drawings or specifications, and we can manufacture bearings tailored to your application.
