FAG QJ315-N2-MPA 75x160x37 mm Four-Point Contact Bearing

Applications in Industrial Systems

The FAG QJ315‑N2‑MPA 75x160x37 is a premium łożysko kulkowe skośne (four-point contact bearing) designed to meet the demands of heavy-duty industrial applications. With inner diameter 75 mm, outer diameter 160 mm and width 37 mm, this bearing supports both axial and radial loads and is ideal for units requiring a compact width but high load-capacity. Typical installation scenarios include bearing housings, large shaft drives, gearboxes, machine tool spindles and heavy rotating equipment where “units of bearing assembly” and “bearing housing” integrations are critical for reliable operation. The design ensures high durability and long service life for industrial applications where downtime and maintenance costs must be minimised.

Key Advantages & Technical Attributes

• The four-point contact configuration allows the bearing to handle axial loads in both directions plus radial loads, making it a true unit łożyskowa solution for dynamic systems.

• The designation “N2-MPA” means two locating grooves in the outer ring (“N2”) for secure mounting in the bearing housing and a brass cage (“MPA”) guided on the outer ring for enhanced durability, improved thermal performance and reduced friction.

• Dimensions 75x160x37 mm provide a great fit for systems where medium-size shafts are used but space in width is limited; suitable for robust industrial demands.

• High durability materials and construction ensure the bearing delivers reliable operation in harsh industrial environments, supporting phrases like “high durability”, “industrial applications”, “unity bearing unit”, and “bearing housing”.

• Optimised for heavy-duty environments: this bearing enables extended maintenance intervals, less wear, fewer replacements and overall lower total cost of ownership in B2B settings.

FAQ

Q1: What is a four-point contact (angular contact) bearing and when should it be used?
A: A four-point contact bearing allows a single bearing unit to carry both radial loads and axial loads in both directions. It is especially useful in applications where space is limited in width but combined load capacity is required. Standard single-row bearings don’t always carry axial loads in both directions effectively.

Q2: What does the code “N2-MPA” indicate on the bearing model?
A: The suffix “N2” refers to two mounting grooves on the outer ring, which assist in secure installation within the bearing housing and improve stability of the outer ring. “MPA” refers to the brass cage guided by the outer ring for enhanced durability and thermal behaviour.

Q3: How to select the correct bearing size for my bearing housing or bearing unit?
A: To choose correctly, match the shaft inner diameter to the bearing bore (75 mm), the housing bore to the bearing outer diameter (160 mm), and ensure that the available width (37 mm) is sufficient. Additionally, assess load types (axial, radial or combined), operating speed, temperature and mounting environment.

Q4: Is this bearing fit for industrial applications with high demands?
A: Yes. The QJ315-N2-MPA is specifically engineered for industrial and heavy-duty applications, bearing housings, large shaft systems and drives where reliability, high durability and capacity for axial + radial loads are crucial.
