Product Description

NU1004 Chrome Steel Timken Cylindrical Roller Bearing 42mm OD 11mm Width Separable

Product Description:

The cylindrical roller bearing is an essential component in various mechanical applications, providing high load-bearing capacity in a compact design. This product summary will delve into the key attributes and specifications of our premium cylindrical roller bearings, particularly focusing on single row cylindrical roller bearings, FAG spherical roller bearings, and four row cylindrical roller bearings.

Our bearings come with a choice of cages, including steel, brass, and nylon options. The steel cage offers exceptional strength and durability, making it suitable for heavy-duty applications and high-speed operations. The brass cage is noted for its resistance to high temperatures and compatibility with high-speed applications where lubricant degradation is a concern. The nylon cage is lightweight and has a good balance of strength and flexibility, reducing inertia forces and lowering operating temperatures.

Regarding lubrication, these bearings are designed for both oil and grease lubrication. Oil lubrication is ideal for high-speed applications where cooling is necessary, as it can dissipate heat efficiently. Grease lubrication, on the other hand, is well-suited for applications where maintenance is difficult, as it provides a longer life span due to its ability to retain lubricants and protect against contaminants.

The material used for the cylindrical roller bearings is of utmost importance, affecting their durability and performance. Our bearings are available in chrome steel and carbon steel. Chrome steel is a high-carbon, chromium-containing alloy that provides excellent hardness and wear resistance, making it the standard choice for most roller bearing applications. Carbon steel is cost-effective and has high strength, making it suitable for applications where stress and load are significant factors.

Vibration level is critical for the performance of bearings in sensitive applications. Our bearings are engineered to have vibration levels ranging from V1, V2, V3, to V4, with V1 being the lowest and V4 the highest level of precision. Lower vibration levels are typically required for applications that demand high precision and smooth operation, such as in precision machinery and instruments.

The dimensions of our cylindrical roller bearings are precisely manufactured to a size of 42*20*12mm. This compact size allows for their integration into various applications without compromising on load capacity or performance.

Single row cylindrical roller bearings are the most widely used type and are characterized by their ability to accommodate radial loads and high speeds. They are designed with a single row of rollers, which allows for a high degree of rigidity and carrying capacity.

FAG spherical roller bearings represent the epitome of precision and quality. These bearings are designed to handle high radial loads and moderate axial loads in both directions. They can also accommodate misalignment and shaft deflections, thanks to their spherical shape of the rollers and the outer ring raceway.

Four row cylindrical roller bearings are especially suitable for heavy radial loads with high speeds and are typically used in rolling mill applications. Their four-row design provides maximum load capacity and radial stiffness, ensuring a high level of accuracy and performance under tough operating conditions.

In conclusion, our cylindrical roller bearings are meticulously engineered to meet the diverse needs of our clients, offering a blend of durability, efficiency, and precision. Whether it is the robust single row cylindrical roller bearings, the adaptable FAG spherical roller bearings, or the heavy-duty four row cylindrical roller bearings, our products are designed to enhance performance and reliability in your operations.

The cylindrical roller bearing is a critical component widely used in various applications, providing high radial load capacity and moderate thrust loads. They are ideal for occasions where high speeds and heavy loads are present. With a brand name that resonates with quality and reliability, such as OEM, SKF, FAG, HRB, and TIMKEN, customers can expect a product that adheres to the highest standards. Originating from China, these bearings come with the reputable ISO9001-2015, SGS, BV, CE, and IAF certifications, assuring global standards of quality and safety.

Our cylindrical roller bearings are available with a minimum order quantity of 10 units, and the price is negotiable to fit your budgetary requirements. Each bearing is meticulously packaged with independent packing to ensure the safety and integrity of the product during transit. With a prompt delivery time of about 5~8 days, your operations will experience minimal downtime. Transactions are secured through T/T in advance, and our impressive supply ability stands at 7.5KKPCS/Month, demonstrating our capacity to fulfill bulk orders with efficiency and punctuality.

These bearings feature an open seal type, which makes them suitable for applications where sealing is not a critical factor, and ease of maintenance is preferred. The weight of each bearing is a mere 0.09kg, making them a lightweight solution for your machinery. Additionally, the design is separable, which simplifies the process of installation, maintenance, and inspection. With two rows, these cylindrical roller bearings can handle a higher radial load, providing a robust performance in demanding scenarios.

Among the various types of bearings we offer, the IKO Cylindrical Roller Bearing is renowned for its precision engineering and durability. The FAG Spherical Roller Bearing is another exemplary product that offers high load capacity and the ability to accommodate misalignment. Furthermore, for applications requiring a high axial load capacity, the INA Cylindrical Roller Thrust Bearings are the go-to choice for many industries.

Our service extends beyond just providing premium bearings. As an agent, we offer comprehensive service solutions, ensuring that clients receive technical support and after-sales service that matches the high quality of our bearings. This customer-centric approach ensures that every purchase is not just a transaction but a long-term investment in reliability and performance for your machinery.
