GE 55 ES 2RS is a radial spherical plain bearing — meaning the inner ring has a spherical (convex) outer surface and the outer ring a matching concave surface. This lets it self-align, accommodating shaft misalignment, tilting or oscillating motion between the shaft and housing.
-
Its construction uses steel-on-steel sliding surfaces (inner and outer rings from high-carbon chromium bearing steel), giving high load capacity, good wear resistance, and strong performance under heavy, static, shock or alternating loads.
-
The “2RS” designation indicates the bearing has double-lip rubber seals on both sides, helping prevent dust, dirt, and moisture ingress — useful in dirty or humid environments — while protecting internal surfaces.
-
It also includes lubrication provisions (lubrication groove and holes), allowing relubrication to maintain smooth operation and prolong service life under load or oscillating motion.
-
GE 55 ES 2RS is built for heavy-duty applications where self-alignment, durability, and load-bearing capacity matter more than high–speed rotation — for example in hydraulic cylinders, heavy machinery linkages, suspension or pivot joints, and industrial equipment where movement or misalignment occurs.

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.
