Overview

322 series Single-row tapered roller bearings;Main dimensions according to DIN 720, separable structure; comprise solid inner and outer rings with tapered raceways and tapered rollers with pressed sheet steel cages;window cage,roller-guided.Normal (ISO 492:2014) tolerance class.

Bore diameter-280 mm; Outside diameter-500 mm;Width-137 mm; Mass-110.5 kg;Cr=2700 kN;C0r=3950 kN;Cur=455 kN.

Similar bearing code No.32256-XL;32256 J2; 32256 are also available in stock.

The suffix J30PC in bearing model designations indicates that the surfaces of the bearing rings and rolling elements have undergone a chemical conversion treatment to form a black protective film.
Primary Functions: Enhanced Lubrication Performance-Under boundary lubrication or mixed friction conditions, it effectively prevents fretting wear and adhesive wear (seizing) on metal surfaces. Enhanced Corrosion Resistance-It provides a certain degree of rust protection. Improved Run-in Performance-It facilitates the formation of a robust lubricating oil film during the initial stages of bearing operation.

This suffix is typically used in conjunction with enhanced load-carrying capacity variants (designated by codes E or XL) and bearings with increased internal clearance (such as C3); a typical full model designation would be, for example, NJ328-E-XL-J30PC-C3.
