The NSK Tapered Roller Bearing offers exceptional performance for a range of applications. Designed to accommodate both radial and axial loads, this bearing embodies precision engineering, ensuring longevity and reliability in demanding environments. With a bore diameter of 40 mm and an outside diameter of 90 mm, it is tailored for efficient operation under high-speed conditions. The Compact design, featuring minimum chamfer dimensions, facilitates optimum fitting in various machinery configurations. This bearing's sophisticated load ratings and lubrication capabilities ensure it meets the stringent demands of modern engineering, ultimately enhancing operational efficiency and equipment lifespan.

High Basic dynamic load rating of 111000 N for enhanced reliability

Effective load centre of 19.5 mm optimises performance in tight spaces

Minimum width requirements (3 mm and 5 mm for large and small side faces respectively) fit easily within housing constraints

Suitable for both grease and oil-bath lubrication catering to diverse operational needs

Compacted outer ring chamfer dimensions reduce stress concentrations enhancing durability

Minimal internal chamfer dimensions contribute to smooth rotational performance

Axial load factors of Y0 and Y1 ensure stability in dynamic applications

Low mass of 0.758 kg reduces overall equipment weight improving energy efficiency
