NU2312-E-TVP2 Single Row Cylindrical Roller Bearing 60×130×46mm Fiberglass Polyamide Cage High Speed

The NU2312-E-TVP2 is single-row NU-type open cylindrical roller bearing with E upgraded roller geometry and TVP2 fiberglass reinforced polyamide window cage. Outer ring has double ribs while inner ring is rib-free, allowing axial floating displacement of inner ring to absorb shaft thermal expansion and prevent bearing seizure during continuous high-speed operation. It features ultra-high radial load capacity, low cage inertia and stable rotation performance, widely used as floating end bearing for industrial motors, medium-heavy gearboxes, compressors and general transmission equipment.

1. E logarithmic optimized roller profile reduces edge stress, improves load bearing capacity and extends service life under deflection and impact load
2. TVP2 lightweight polyamide cage features low rotational inertia, excellent self-lubricating property and stable high-speed operation up to 120℃ continuous temperature
3. NU floating inner ring design compensates thermal elongation of shaft, eliminates thermal stress and avoids bearing locking for long-time running equipment
4. Separable inner and outer ring structure simplifies installation, disassembly and routine maintenance inspection
5. Large radial load capacity fits medium-high speed heavy-duty industrial transmission working conditions
6. Customizable options include C3 extra clearance, OEM laser marking and special high-temperature lubricating grease
