F‑201380.RNU Full‑Complement Cylindrical Roller Bearing 30.4*52*22mm Hydraulic Pump Printing Machine Precision Spare Part
- F‑201380.RNU is an open‑style full‑complement single‑row cylindrical‑roller bearing with no supplied inner‑ring. Its double‑flanged outer ring retains all rollers, and the hardened and finely‑ground shaft surface acts as the inner raceway. The full‑roller layout delivers outstanding radial‑load capacity and high‑speed performance. It occupies compact radial space and is widely used inside hydraulic pumps, printing‑machine spindles, gearboxes and precision‑transmission assemblies.

Q1: Why does F‑201380.RNU come without an inner ring?
A1: The hardened, finely‑ground shaft surface serves as the inner raceway to shrink overall installation dimension.
Q2: What kind of load can this full‑complement roller bearing carry?
A2: It is primarily designed to withstand heavy radial load and can bear limited minor axial force.
Q3: Which lubriion way reaches the higher limiting rotational‑speed?
A3: Oil lubriion can reach the maximum limiting speed of 14000 rpm.
Q4: What advantage does the full‑complement roller configuration bring?
A4: More installed rollers greatly raise the radial load rating compared to caged‑type bearings.
Q5: Does this precision bearing have built‑in sealing components?
A5: It adopts open‑type structure, and users need external dust‑proof measures under dusty working‑conditions.
