Crossed Cylindrical Roller Slewing Bearing XU05 0077 Charactors and Applications

XU05 0077 Crossed Cylindrical Roller Slewing Bearing

Basic dimensions: 

Inner diameter: 40 mm

Outer diameter: 112 mm

Width: 22 mm

Weight: 1.4 kg

Structure: Integrated inner & outer ring, pre-drilled mounting holes, gearless crossed cylindrical roller slewing bearing, 90° alternately arranged cylindrical rollers

Bearing Characteristics

1. Multi-direction load capacity: Can bear radial load, axial load and overturning moment simultaneously in one compact unit
2. High rigidity & high rotational accuracy: Preloaded design, precision grade P4 / P5 / P6 available; small rotation torque, stable positioning accuracy
3. Compact thin-section design: Save installation space; no need for extra flanges or support seats, easy assembly. Both inner ring rotation and outer ring rotation are supported
4. Sealed structure with grease nipple: Good dust-proof performance, convenient lubrication maintenance
5. Material: Chrome steel / 42CrMo; working temperature range approx -25℃ ~ +80℃
