F-225035 Hydraulic Pump Crescent Bearings 22x50x27mm

Product Name

F‑225035 Hydraulic Pump Crescent Bearing 22×50×27 mm

Product Overview

The F‑225035 is a precision‑engineered full complement cylindrical roller bearing designed specifically for hydraulic pump applications. With a compact footprint of 22 mm (bore) × 50 mm (O.D.) × 27 mm (width), this single‑row, open‑type bearing features a cageless (full complement) design that maximises the number of rolling elements, delivering outstanding radial load capacity and rigidity. Its unique crescent‑type geometry makes it an ideal choice for internal gear pumps and other hydraulic systems where space is limited but reliability is critical.

Key Specifications

Performance Features

• Full complement design – no cage means more rollers, significantly increasing both dynamic and static load ratings compared to caged bearings of the same size.

• High radial rigidity – excellent resistance to deformation under heavy loads, essential for high‑pressure hydraulic environments.

• Crescent‑type configuration – specially shaped to fit the internal geometry of crescent pumps, ensuring smooth fluid displacement and stable operation.

• C3 internal clearance – accommodates thermal expansion and shaft misalignment, maintaining consistent performance over a wide temperature range.

• Open construction – facilitates easy lubrication (oil or grease) and routine maintenance.

• Compact dimensions – 22×50×27 mm, saving valuable space in pump assemblies.

Typical Applications

• Hydraulic pumps – particularly internal gear pumps (crescent‑type) used in construction machinery, agricultural equipment, and industrial systems.

• Power steering pumps – where high load capacity and compact size are required.

• Lubrication pumps – for reliable oil delivery under variable pressure conditions.

• Mobile and off‑highway hydraulic systems – subject to shock loads and continuous operation.
