NU1007EM Brass Cage Cylindrical Roller Bearing , NU1007M Single Row Roller Bearing 35*62*14mm

1. Product Overview

NU1007EM and NU1007M are single row separable cylindrical roller bearings with removable inner ring, unified metric boundary dimensions d35×D62×B14mm. The core difference lies in cage material: NU1007EM adopts solid brass machined cage; NU1007M uses stamped steel cage.

This NU10 single row series features two side ribs on outer ring and rib-free inner ring design, inner ring can be separated freely for easy independent installation of shaft and housing. Cylindrical rollers form line contact with raceway, delivering outstanding radial load capacity while adapting to medium-high speed continuous rotation. All rings and rollers are made of fully quenched GCr15 bearing steel with ultra-precision mirror grinding raceway, stable rotation precision, low vibration and low noise. Widely used for high-speed electric motors, gear reducers, hydraulic pumps, textile machinery and general industrial transmission shafts.

3. Core Advantages

1. Separable inner ring design, split assembly of shaft and bearing housing, greatly simplify maintenance disassembly process for long transmission shafts.
2. Two cage versions for differentiated selection: brass EM cage suits high-speed, high-temperature and long continuous operation; steel M cage reduces cost for standard general equipment.
3. Line contact cylindrical roller structure, excellent radial load bearing performance, stable operation under heavy radial impact load of gearbox and pump.
4. Ultra-smooth superfinished rolling surface, low friction coefficient, effectively control temperature rise during long-time high-speed rotation, avoid overheating failure.
5. GCr15 full quenching heat treatment, surface hardness HRC60-65, excellent anti-fatigue and wear resistance, extend service cycle of motor and transmission equipment.
6. No rib inner ring allows tiny axial sliding compensation, release thermal expansion stress of shaft during high-speed operation, prevent bearing locking.
7. Standard universal metric mounting size, fully interchangeable with global NU1007 series cylindrical roller bearings, no modification for existing shaft and housing.
8. Comprehensive customized service: P4/P5 high precision upgrade, C3 clearance adjustment, OEM laser marking, neutral export carton anti-rust packaging, special high temperature grease pre-filling.

8. FAQ

Q1: What is the difference between NU1007EM and NU1007M?
A1: The difference is cage material. NU1007EM is solid machined brass cage, suitable for high speed and high temperature working conditions; NU1007M is stamped steel cage, cost-effective for general medium-speed equipment.
Q2: What is the feature of NU series separable cylindrical roller bearing?
A2: Outer ring with double ribs, inner ring without rib, inner ring can be separated, convenient split installation of shaft and bearing seat, and allows small axial sliding of inner ring to absorb shaft thermal expansion.
Q3: Can NU1007 series bear axial load?
A3: Mainly bear pure radial load, can only withstand tiny incidental axial force, if large axial load exists, matched thrust bearing is required.
