N311 Cylindrical Roller Bearing

N311 Cylindrical Roller Bearing | Professional Industrial Solution

Overview

The N311 Cylindrical Roller Bearing represents a precision-engineered solution for medium-duty industrial applications requiring high radial load capacity and operational reliability. This single-row bearing features a 55mm bore diameter, 120mm outer diameter, and 29mm width, making it ideal for equipment operating under heavy radial loads. The N311 designation indicates a specific flange configuration where the inner ring has double integral flanges while the outer ring remains flange-free, allowing axial displacement accommodation in both directions. This design effectively addresses thermal expansion challenges commonly encountered in electric motors, gearboxes, and industrial machinery.

Design Features and Working Principle

The N311 utilizes round and hollow rollers that make line contact with the internal and external ring raceways. This contact design disseminates loads over a bigger surface region compared to ball orientation, coming about in higher stack capacity and moved forward unbending nature. The roller course of action permits the bearing to handle considerable outspread strengths whereas keeping up smooth turn beneath different working conditions.

The rib arrangement plays a pivotal part in execution. The internal ring's twofold ribs direct the rollers absolutely amid turn, whereas the external ring's flange-free plan grants hub shaft development relative to the lodging. This coasting capability anticipates push concentration that seem lead to untimely disappointment in thermally dynamic environments.

The squeezed steel cage keeps up ideal roller dividing and gives satisfactory grease dispersion. The cage plan guarantees reliable roller situating all through the stack zone whereas permitting productive grease stream to basic contact ranges.

Performance Advantages

High Radial Load Capacity: The line contact design enables the N311 Cylindrical Roller Bearing to handle radial loads significantly higher than equivalent ball bearings. This capability makes it suitable for heavy-duty applications in mining equipment and large reducers.

Hub Uprooting Convenience: The N-type arrangement permits free pivotal development, making it perfect as a coasting bearing in frameworks where warm extension happens. This anticipates official and diminishes inside stretch buildup.

Separable Plan: The bearing components can be mounted and gotten off freely, decreasing establishment time and upkeep complexity. This include is especially important in expansive apparatus where availability is limited.

Operational Flexibility: Accessible accuracy classes from P0 to P4 permit determination based on particular application necessities, adjusting taken a toll and execution needs viably.

Primary Applications

The N311 finds extensive use in applications requiring robust radial load handling:

• Large Speed Reducers: Provides reliable support for gear systems in industrial transmission equipment
• Mining Machinery: Withstands heavy loads and shock conditions in crushers and conveyors
• Electric Motors: Serves as floating bearing to accommodate thermal expansion
• Industrial Gearboxes: Supports shaft systems in power transmission applications

Quality Assurance
