30mm Bore Flange Pillow Block Bearing SUCP206

UCP206 bearing is an industrial standard component designed by integrating an outer spherical ball bearing and a cast bearing seat. It adopts a spherical outer surface structure to achieve automatic centering function Its inner diameter is 30mm, outer diameter is 42.9mm, and total height is 165mm. It is suitable for various mechanical installation scenarios through top wire or eccentric sleeve fixation. This model is suitable for supporting structures in industrial fields such as mining, metallurgy, machine tools, and engineering machinery, and has technical characteristics such as perfect sealing and strong load-bearing capacity.
Structural Design
Adopting a dual integrated structure of outer spherical bearings and cast bearing seats, the inner ring width is greater than the outer ring to form an axial positioning reference. The outer spherical surface is matched with the spherical inner hole of the bearing seat, allowing for a ± 2 ° adjustment angle to compensate for installation errors The sealing structure adopts double-sided contact seals
Technical Specifications
The core dimensions include an inner diameter of 30mm ± 0.002mm, an outer diameter of 42.9mm, and a total height of 165mm. The installation dimensions cover:
Base height H2: 83mm
Installation hole distance A: 48mm Rated dynamic load 12.3kN, static load 6.65kN, ultimate speed 3400r/min (grease lubrication condition)
Product Features
Compared with ordinary deep groove ball bearings, it has three technical advantages:
Heart regulating function reduces eccentric load damage caused by axial bending
Integrated structure reduces installation complexity
Cast iron bearing seat enhances radial load bearing capacity
Installation specifications
The mating surface of the shaft must meet the h6 level tolerance and be kept clean. Follow the steps below during installation:
1. Remove burrs and rust from the surface of the shaft
2. Push the bearing axially into the installation position
3. Use a torque wrench to tighten the top thread (recommended torque of 12N · m)
4. Inject lithium based grease to 30% of the cavity volume. It is strictly prohibited to directly hammer the outer ring or bearing seat to avoid structural deformation
