FAG 51184-MP Axial ball bearing 420x500x65mm

Buy online your FAG Axial ball bearing 420x500x65mm reference 51184-MP from US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This FAG 51184-MP is a heavy-duty axial ball thrust bearing designed to support high axial loads in one direction on CNC machines and industrial equipment. It is suitable for shaft end-thrust support, ballscrew assemblies, gear stages and rotary positioning systems where precise axial positioning, stable preload and reliable thrust capacity are required.

The bearing has a dimensional envelope of 420 x 500 x 65 mm, making it suitable for compatible housings designed for the 51184 series. Its machined brass MP cage provides stable ball guidance and supports reliable operation in large-bore thrust applications. Proper axial seating, lubrication and alignment of the mating surfaces are important for achieving reliable service life.

The 51184-MP is designed for single-direction axial loading and is not self-aligning, so accurate installation and correct housing and shaft fits are essential to prevent uneven loading. For applications requiring axial load capacity in both directions, a suitable paired bearing arrangement can be used according to the machine design.

Manufactured in Germany, this FAG thrust bearing is suitable as a CNC replacement component, industrial spare part, replacement bearing or emergency spare. It can be used on heavy machine tools, ballscrews, presses, extrusion equipment, industrial gearboxes and large rotary positioning systems where restoring axial support is critical.

Keeping a stocked spare bearing available can help reduce downtime following wear, brinelling, lubrication failure or damage to the existing thrust bearing assembly. The FAG 51184-MP is particularly suitable for maintenance, machine rebuilds and retrofit projects where the original bearing dimensions and load direction must be maintained.

Each unit supplied by Cnc-shopping can be visually inspected and dimensionally checked by qualified technicians, including verification of the bearing dimensions and smooth rotation when applicable. Products are protected against corrosion and securely packaged for industrial transportation, with a commercial warranty, fast dispatch depending on availability, worldwide shipping, obsolete-part sourcing, repair and exchange services available according to stock and condition.

Frequently asked questions about 51184-MP:

Is 51184-MP single or double direction?
It is a single-direction axial ball bearing. It carries thrust in one direction only and requires a paired arrangement if you need axial support both ways.

What are the main dimensions of this FAG unit?
The bearing measures 420 mm ID, 500 mm OD and 65 mm width, matching the standard 51184 series envelope for drop-in replacement.

Does it handle radial loads?
No. This design is intended for axial loads. Any radial load should be carried by a separate radial bearing in the assembly.

What does the MP suffix indicate?
MP designates a machined brass cage. This cage style provides robust ball guidance for large-bore thrust applications under sustained axial load.

Typical use in CNC machinery?
It is commonly found in large ballscrew thrust housings, heavy rotary tables and gearbox thrust stages where accurate axial positioning and high thrust capacity are required.
