Needle Roller Thrust Bearing AXK3552 by uxcell 35mm ID 52mm OD

Description

Product Overview

The uxcell Needle Roller Thrust Bearing model AXK3552 is engineered for high‑performance axial load handling in a compact form factor. Measuring 5.51 x 3.94 x 1.97 inches and weighing just 0.91 ounces, the bearing combines a robust chromium steel roller set with a precision‑machined steel cage, delivering exceptional durability while maintaining low friction. The inner diameter of 35 mm, outer diameter of 52 mm, and a base thickness of 2 mm (extended to 4 mm when paired with the included AS3552 washers) provide a versatile fit for a wide range of industrial components. With a static load capacity of 80.1 kN and a dynamic load capacity of 16.9 kN, the bearing can sustain heavy axial forces in one direction, making it ideal for applications such as gearboxes, conveyor systems, and high‑speed spindles. The maximum rotational speed of 5,500 RPM ensures reliable operation in demanding environments, while the chromium‑treated rollers resist heat buildup and wear, extending service intervals. The integrated washers act as supplemental raceways when adjacent parts cannot serve that function, simplifying installation and reducing the need for additional hardware. Designed to meet the rigorous standards of the industrial and scientific market, this bearing holds a best‑sellers rank of #67 in Needle Roller Bearings on Amazon, reflecting its popularity among engineers seeking dependable performance.

Usage

This thrust bearing excels in settings where axial loads dominate, such as in vertical shafts, hydraulic actuators, and precision machining equipment. Its compact dimensions allow it to be incorporated into tight spaces within robotic arms, CNC machines, and automated assembly lines. The chromium steel rollers provide excellent heat tolerance, making the bearing suitable for high‑speed applications that generate significant thermal energy. Users in the automotive aftermarket often employ this bearing in transmission assemblies and differential housings, where reliable load transfer and minimal vibration are critical. In the aerospace sector, the bearing’s low noise profile and high static load rating support lightweight structural components that must endure sustained forces without compromising performance. Maintenance technicians appreciate the ease of installation: the included washers eliminate the need for custom machined raceways, and the steel cage guides the rollers to reduce wear and maintain alignment over prolonged service periods. Whether mounted on a motor shaft, a pump housing, or a linear actuator, the AXK3552 delivers consistent, low‑maintenance operation across a broad temperature range.

FAQ

What is the maximum speed this bearing can handle?

The AXK3552 is rated for a maximum rotational speed of 5,500 RPM, which covers most high‑speed industrial applications while maintaining stability and low noise.

Can this bearing be used for bidirectional axial loads?

No. The needle roller thrust bearing is designed to accommodate axial loads in one direction only. For bidirectional loads, a different bearing type should be selected.

Do the included washers replace the need for custom raceways?

Yes. The AS3552 washers act as supplemental raceways, allowing the bearing to be installed even when adjacent components cannot serve as raceways, simplifying the mounting process.

What maintenance is required for optimal performance?

Regular visual inspection for signs of wear, lubrication according to the manufacturer’s recommendations, and ensuring the bearing operates within its temperature and speed limits will keep it performing at peak efficiency.

Is this bearing compatible with standard shaft sizes?

The bearing’s inner diameter of 35 mm matches common shaft sizes in many industrial machines. Verify your shaft dimensions before installation to ensure a proper fit.
