As an important member of the thrust ball bearing family, the 51104 flat thrust bearing plays a key role in axial support across various mechanical fields. With its precise dimensional design and reliable performance, it provides solid guarantees for the stable operation of various equipment.
Basic Dimensions
Inner Diameter (d): 20mm - Carefully designed to fit numerous standard shaft diameters, ensuring tight coordination with the shaft for efficient transmission of axial force.
Outer Diameter (D): 35mm - Provides sufficient installation space for rolling elements and cage assembly while meeting compact layout requirements.
Thickness (T): 10mm - Balances load-bearing strength and operational flexibility while minimizing friction and heat generation.
Structural Features
Adopts a separable structure consisting of shaft washer (interference fit with shaft), housing washer (transition fit with equipment housing), and steel ball-cage assembly. This design allows individual installation and disassembly of components, simplifying equipment assembly and maintenance.
Note: The 51104 flat thrust bearing can only bear unidirectional axial loads and cannot withstand radial loads. Requires matching with radial support components for complete shafting support solutions.
Core Materials
Bearing Rings: High-carbon chromium bearing steel (SAE-52100 or GCr15) with hardness HRC 60-64. Stainless steel available for corrosive environments.
Rolling Elements: Precision-ground bearing steel balls with micron-level roundness control. Ceramic rolling elements (silicon nitride) available for high-temperature, high-speed applications.
Cages: Nylon materials (PA66) for conventional use; stamped steel or brass cages for high-speed or high-temperature environments.

Typical Application Fields
Small and Medium-sized Mechanical Equipment: Dental treatment chair lifting mechanisms, barcode printer paper-feeding shaft support, small elevator traction machine axial positioning
Transmission Systems: Reducer output shaft axial support, motor end covers, Roots pump rotor axial limit
Light Industry and Agricultural Equipment: Knitting machinery roller shafts, small tractor hydraulic systems, canning processing equipment main shafts
With its precise dimensions of 20mm inner diameter, 35mm outer diameter, and 10mm thickness, combined with separable structure, high-quality wear-resistant materials, and stable load-bearing performance, the 51104 flat thrust bearing has become an ideal choice for many small and medium-sized machinery requiring high axial support accuracy and space compactness.
