Project Details
Basic Attributes Model 4V-4164, Steel Flange Terminal Sleeve Bearing, Quantity 1–4 pieces per unit, used for sensor/valve terminals, radial support for small shaft systems, suitable for light load (≤1 kN), low speed (≤1500 rpm) conditions
Key Dimensions Inner diameter 10 mm, outer diameter 22 mm, flange diameter 28 mm, total length 18 mm, flange thickness 3 mm, sleeve wall thickness 6 mm, suitable shaft diameter 10 mm (h6 tolerance), mounting hole diameter 22 mm (H7 tolerance)
Material and Process SAE 1010/1020 low carbon steel, surface galvanized/passivated, flange integrally formed, sleeve inner wall Ra≤0.8 μm, suitable temperature -20℃ to +100℃
Performance Parameters Radial rated dynamic load ≈1.2 kN, radial rated static load ≈2.5 kN, friction coefficient ≤0.15, axial load ≤0.3 kN, assembly clearance 0.01–0.03 mm. Compatible models: Cat 305/306 mini excavators, small loaders (e.g., 226B), hydraulic control systems, sensor terminals, cable connector shafts.
Installation and maintenance points:
Clean the bearing and mounting holes before installation, ensuring no burrs or oil contamination. Mounting hole roundness ≤0.01 mm, surface roughness Ra ≤1.6 μm.
Use cold pressing assembly. Use specialized tooling to press evenly, avoiding hammering that could deform the flange or crack the sleeve.
The flange should fit snugly against the mounting surface without gaps. Radial runout after assembly should be ≤0.02 mm. It is recommended to check for looseness and wear every 1000 hours; replace if abnormal.
The compatible lubrication method is grease lubrication (e.g., Cat 106-9900 grease), with a filling amount of 1/3–1/2 of the bearing cavity volume.
