Key Features & Benefits:

1. NU1052 bearing’s single-row cylindrical roller design with cage for higher-speed operation and reduced roller-to-roller contact, improving running smoothness
2. Solid inner and outer rings with a precision cage that keeps rollers separated, lowering friction and wear under continuous operation
3. High radial load capacity and rigid construction that provide stable support in heavy-duty and high-impact applications
4. NU design (outer ring with two ribs, inner ring without ribs) that permits controlled axial displacement of the shaft in both directions
5. Separable inner and outer rings simplify mounting and dismounting, speeding up installation and maintenance
6. Well suited for gearboxes, pumps, compressors, electric motors, and agricultural machinery where radial loads and shaft movement occur

FAQ:

Q1: What type of bearing is the NU1052-M1?
A: This bearing is a single-row cylindrical roller bearing with cage (NU design).

Q2: What loads does this bearing support?
A: It primarily supports heavy radial loads and provides high rigidity; it does not bear significant axial loads in service.

Q3: Does this bearing allow axial shaft movement?
A: Yes. As an NU-type bearing, it permits axial displacement of the shaft relative to the housing in both directions (suitable as a floating bearing).

Q4: What lubrication does this bearing require?
A: Use appropriate high-quality grease or oil lubrication per operating speed and temperature. Follow manufacturer lubrication recommendations and service intervals.

Q4: How can I inspect the NU 1052 EM for wear or damage?
A: Check for abnormal noise or vibration, rough rotation, discoloration from overheating, pitting, spalling, or visible roller/raceway damage. Replace if you observe these signs.
