GQZ E5022NRNT Double Row Full Complement Cylindrical Roller Bearing 110×170×80mm For Crane Pulley Assemblies

E5022NRNT is double row full complement cylindrical roller bearing without cage. NR means outer ring with snap ring groove and equipped with retaining snap ring; NT stands for sealed reinforced structure. The full roller arrangement achieves maximum roller quantity, delivering extraordinary radial load capacity. It can withstand heavy radial load and limited bidirectional axial load. Widely adopted for crane pulleys, lifting sheaves, port hoisting machinery and heavy material handling equipment working under continuous heavy impact loads.

1. Full complement roller design, maximum number of rollers, ultra-high static & dynamic load capacity
2. NR structure: outer ring snap ring groove with retaining ring for reliable axial positioning
3. NT optimized side sealing structure, reduce foreign matter intrusion for outdoor lifting conditions
4. Mainly bears heavy radial load, also supports limited bidirectional axial load
5. Robust ring for enduring frequent impact and alternating loads on crane pulleys
6. Customizable options: OEM laser marking, special clearance, enhanced anti-corrosion treatment
   Effectively reduce premature fatigue failure and extend service life of hoisting pulley assemblies.
