The NU 315 ECP is a high-quality single-row cylindrical roller bearing built to deliver reliable and efficient performance in heavy-duty applications. With an inner diameter of 75 mm, an outer diameter of 160 mm, and a width of 37 mm, this bearing balances compactness with strong load-bearing capability.
Designed with an open, NU-type configuration — featuring a fixed outer ring (double-flanged) and a sliding inner ring — the NU 315 ECP allows axial movement of the shaft relative to the housing. This makes it ideal for machinery where thermal expansion or shaft displacement may occur.
A key advantage is its glass-fibre reinforced polyamide (PA66) cage, which keeps the rollers aligned, reduces friction, and supports smooth rotation even under heavy loads. The cage design, combined with optimized roller-end and flange contact geometry, promotes efficient lubricant film formation — leading to lower wear and extended service life.
With a dynamic load rating of approx. 280 kN and a static load rating around 265 kN, NU 315 ECP can handle substantial radial loads. Its speed rating (up to ~5300 rpm) keeps it suitable for moderately high-speed machinery. The separable design also allows for easier mounting, dismounting, and maintenance — a practical benefit in industrial setups.
Commonly used in gearboxes, industrial motors, heavy machinery, conveyors, and other mechanical systems where high radial loads, axial displacement, and reliable long-term performance are required.
In short: if your application demands a robust, high-capacity bearing with flexibility for axial displacement, low friction, durability, and easy installation/maintenance, the NU 315 ECP offers an excellent balance of size, performance, and reliability.
The 3312-2RS SDKF bearing is a high-performance double-row angular contact ball bearing designed to deliver exceptional strength, stability, and durability under demanding operating conditions. Built to handle high radial loadsalong with axial loads in both directions, it is widely used in machinery that requires reliable and smooth rotational performance.
A key advantage of this bearing is its 2RS sealing system, which features high-quality rubber seals on both sides. These seals effectively protect the bearing from dust, moisture, and other contaminants while locking in the lubricant. This ensures longer grease life, reduced wear, and minimal maintenance—ideal for equipment operating in harsh or dirty environments.
At the heart of its construction is a precision-engineered cage, typically made from pressed steel or reinforced polyamide, depending on the specific SDKF variant. This cage ensures optimal ball spacing, reduces friction, improves heat dissipation, and enhances overall operating efficiency. Its strong and stable structure helps the bearing run quietly and smoothly, even under heavy loads or higher speeds.
Crafted from premium bearing steel, the 3312-2RS SDKF offers excellent resistance to wear, deformation, and fatigue, ensuring long service life and consistent performance. Thanks to its dual-row design, it provides increased rigidity, making it ideal for applications with combined or fluctuating loads.
Common applications include industrial machinery, agricultural equipment, gearboxes, pumps, conveyors, and automated systems, where reliability and long-lasting performance are essential.
If you need a bearing that offers excellent load capacity, reliable sealing, smooth operation, and durable cage construction, the 3312-2RS SDKF is a dependable and widely trusted solution.
