When axial forces dominate and the shaft may not sit perfectly aligned with the housing, a spherical roller thrust bearing is often the right choice. Its spherical rollers running on a spherical seat raceway give the bearing self-aligning capability. NSK supplies this design for demanding machinery such as presses, cranes, ship propellers and large gearboxes.
Reading the code helps you identify what you are ordering. In a designation like 29488EM, the letters EM tell you the bearing has a one-piece machined brass cage guided by the inner ring, a construction that adds strength and helps with heat dissipation. The numeric portion, 29488, defines the size and load capacity. If any part of the code is unclear, check with a specialist before you order.
These bearings suit equipment where axial load is the main force and shaft deflection is a possibility: hydraulic presses, high-tonnage cranes, rotary tables, marine propellers, large speed reducers and overhead crane supports. They also appear in mills and crushers, where loads are severe and alignment is difficult to achieve.
Selection depends on the axial load's size and direction, the rotation speed and the operating environment. Lubrication is critical: grease or oil must form an adequate film to avoid premature wear. During mounting, make sure the outer ring's spherical raceway seats correctly in the housing. Initial alignment is less critical than with other bearing types, but check that the shaft is perpendicular to the base.
Interchangeability requires care. Spherical roller thrust bearings from different brands can differ in dimensions and capacities, so a similar code is not enough. Compare bore diameter, outer diameter, height and permissible load. If you have another brand's code, we can help you find the NSK equivalent. Always verify tolerances and internal clearance before substituting one manufacturer's bearing for another.

Frequently asked questions
- What does the EM suffix mean in an NSK bearing?
- EM indicates a one-piece machined brass cage, inner ring guided. This cage provides greater mechanical strength and better thermal behavior than stamped steel cages, particularly under high loads or moderate speeds.
- Where are spherical roller thrust bearings used?
- They are found in equipment with very high axial loads and possible misalignment: presses, cranes, rotary tables, marine propellers, large gearboxes and overhead crane supports. They also appear in steel plants, cement plants, mining operations and shipyards.
- How do I request a quote for an NSK spherical roller thrust bearing?
- Send us the complete code or the main dimensions: bore diameter, outer diameter and height. With that information we will quote promptly. If you have a code from another brand, we can also identify the equivalent NSK reference.
