Finding the right cylindrical roller bearing for automotive AC compressors often means sifting through incompatible dimensions or dealing with early wear from substandard materials. When a bearing fails, it leads to costly downtime and repairs—not just for the compressor, but potentially the entire cooling system.
The RN208M and RN208-E-XL-M1 cylindrical roller bearings are designed to address these challenges. With ISO 9001-certified production and rigorous material testing, they meet the radial load requirements of auto AC compressors while maintaining precise dimensions (40*70*18 mm) for seamless installation. Our extensive inventory ensures you can source this bearing quickly, whether you need a single unit or bulk quantities.
This cylindrical roller bearing excels in environments with high radial loads, such as the rotating shafts of AC compressors. Its separated structure allows for easy mounting and dismounting, simplifying maintenance. The non-aligning design ensures stability under consistent radial force, while the open seal type accommodates various lubrication methods to suit specific operating conditions.
The choice of materials directly influences bearing longevity: chrome steel and bearing steel options provide high hardness and wear resistance, critical for withstanding the continuous rotation in AC compressors. Precision ratings from P0 to P2 allow customization based on application tolerance needs—higher precision (P4/P2) reduces vibration (V1-V4 grades) for quieter operation. The iron, brass, or nylon cage options further tailor the bearing to temperature and load requirements, with brass cages offering superior heat resistance for under-hood environments.
Investing in a quality cylindrical roller bearing like the RN208M series reduces long-term costs. Inferior bearings with imprecise dimensions (outside diameter ranging from 35mm-180mm) or inadequate material hardness often fail prematurely, leading to compressor lock-up and system damage. By choosing a bearing that meets DIN, ISO, or JIS standards, you ensure compatibility with international equipment designs and minimize the risk of unplanned maintenance.
Our production process adheres to ISO 9001 standards, with raw material inspection and成品 testing for dimensions, hardness, and surface finish. We stand behind the quality of our bearings with a warranty against manufacturing defects, ensuring you receive reliable components. Whether you need our BDL brand or specific international brand equivalents, our procurement渠道 covers a wide range of options to meet your exact specifications.
Whether you need the RN208M, RN208-E-XL-M1, or any other cylindrical roller bearing, we can provide pricing and availability quickly. Share your required model, dimensions, and quantity, and our team will assist with your order.
Q: Do you supply bearings from other brands besides BDL?
A: Yes, we offer a wide range of bearings, including international and domestic brands, and can source specific models as per your requirements.
Q: How can I confirm if this bearing fits my AC compressor?
A: Provide your equipment model or the required dimensions (d x D x B), and our technical team will verify compatibility with the RN208M series.
Q: What is your warranty policy for these bearings?
A: We provide a warranty against manufacturing defects; terms are specified in the sales contract.
Q: What is the minimum order quantity for the RN208M bearing?
A: We accept low minimum orders, making it easy to test samples before placing bulk orders.
Q: How quickly can you ship after ordering?
A: In-stock items ship within 3-10 days; larger quantities may require additional production time.
Q: Do you offer OEM or ODM services for bearings?
A: Yes, we support custom bearing production based on your drawings or specifications.
