NJ 310 MTM 50x110x27 Cylindrical Roller Bearing

Main Description:

The NJ 310 50x110x27 cylindrical roller bearing (MTM) is engineered for demanding industrial environments where high load capacity, long service life, and consistent shaft alignment are critical. Common English-language search queries reveal that engineers and procurement managers often use phrases such as “cylindrical roller bearing NJ 310”, “NJ 310 50x110x27 bearing”, “heavy-duty roller bearing 50x110x27”, “industrial bearing for gearbox”, or “NJ 310 MTM bearing replacement”. Such keywords reflect clear market demand for high-performance bearings in heavy machinery, drives, and industrial equipment.

This bearing belongs to the single-row cylindrical roller bearing family with the “NJ” configuration — meaning the inner ring has one flange while the outer ring has two flanges. This design allows for axial positioning of the shaft in one direction while providing excellent radial load capacity. It is especially suited for applications with high radial loads, such as gearboxes, presses, rollers, conveyors, heavy-duty conveyors, industrial pumps, and manufacturing equipment.

With precision dimensions — 50 mm inner diameter, 110 mm outer diameter, 27 mm width — this bearing fits standardized housings and bearing units, easing integration into existing systems or new builds. Its robust steel construction and optimized roller contact geometry ensure low friction, stable shaft guidance, and minimized wear under heavy load and continuous operation. This makes the NJ 310 bearing a preferred choice for demanding industrial use, where downtime is costly and reliability is essential.

For procurement teams, maintenance departments, and machine builders, NJ 310 50x110x27 stands out as a durable, maintenance-friendly, and cost-effective bearing option. Keywords like “industrial roller bearing,” “heavy duty bearing,” “cylindrical roller bearing 50x110x27,” “industrial gearbox bearing,” and “bearing unit for heavy loads” naturally align with this description, boosting SEO relevance and search visibility.

Durability, Maintenance and Supply-Chain Advantages:

The NJ 310 bearing’s heavy-duty design significantly reduces maintenance frequency thanks to its robust roller-to-race contact and optimized geometry, which limits wear and preserves bearing integrity under continuous load. For B2B buyers, the bearing’s standard dimensions and compatibility with common housings simplify logistics and spare-parts management. Its readiness for immediate dispatch supports fast repairs and minimal downtime — crucial in industrial settings where production continuity is key.

FAQ

Q1: What does “NJ” mean in the bearing designation?
A1: “NJ” indicates the internal flange configuration — one flange on the inner ring and two on the outer ring — allowing the shaft to be axially located in one direction while bearing high radial loads.

Q2: What dimensions define NJ 310 50x110x27?
A2: Inner diameter 50 mm, outer diameter 110 mm, width 27 mm — standard size for many industrial housings and bearing units.

Q3: For what kind of applications is this bearing best suited?
A3: Heavy-duty applications like gearboxes, rollers, conveyor systems, industrial presses, pumps, and other machinery requiring high radial load capacity and stable shaft positioning.

Q4: How does a cylindrical roller bearing compare to a ball bearing for heavy loads?
A4: Cylindrical roller bearings generally offer much higher radial load capacity, better stiffness, and longer service life under heavy load compared to ball bearings — making them better suited for industrial machines and heavy equipment.

Q5: What maintenance is needed for NJ 310 bearings?
A5: With correct lubrication and installation, they deliver long, low-maintenance service. Regular inspection and re-lubrication under heavy duty conditions are recommended to maximize lifespan.
