51104 Thrust Ball Bearing | Medium-Load Single Direction Axial Support Bearings
The 51104 thrust ball bearing is a medium-load single-direction axial bearing in the standard 5110 series, filling the performance gap between small-size 51103 and heavy-duty 51105 thrust bearings. Designed exclusively for unidirectional axial pressure and vertical shaft positioning, this open-style thrust bearing features balanced structural size, moderate load capacity and stable rotary performance. It supports versatile industrial material configurations, delivering tailored wear-resistant, rust-proof and anti-corrosion solutions for medium-load mechanical systems in conventional and moderately harsh working environments.
51104 Thrust Bearing Structure And Performance Benefits
Built with a detachable three-part structure including a shaft washer, housing washer and precision steel ball array, the 51104 thrust bearing boasts a fully open design for effortless installation, disassembly and routine lubrication upkeep. Its precision-polished raceway uniformly distributes axial stress, lowering rotational friction and mechanical wear during continuous cyclic operation. Strictly engineered to bear only axial loads with no radial load tolerance, it effectively controls shaft axial play, reduces operational vibration and ensures consistent vertical stability for medium-load industrial machinery.
51104 Bearing Material Properties And Industrial Applications
High Carbon Chrome Bearing Steel (GCr15): The universal standard material for 51104 industrial thrust bearings, featuring exceptional compressive rigidity, outstanding anti-fatigue and wear-resistant performance. It maintains long-term stable operation under continuous medium axial loads with high cost-effectiveness and low failure rates. Ideal for general industrial machinery, vertical rotating shafts, medium-duty lifting tools, packaging equipment and conventional mechanical axial support systems.
304 Stainless Steel: Offers reliable atmospheric oxidation resistance and inherent rust-proof capability, perfectly adapting to humid, dusty and ventilated working environments. It retains stable mechanical performance under regular loads, serving as a cost-effective anti-corrosion option for light industrial equipment, food processing auxiliary machinery, outdoor civilian mechanical fittings and general low-corrosion positioning components.
420 Stainless Steel: Balances high hardness and mechanical toughness with mild chemical corrosion resistance, effectively resisting daily friction wear and weak medium erosion. It delivers steady precision rotation under frequent start-stop cycles, widely used in precision detection instruments, light medical equipment, optical machinery and mid-range automated precision devices.
440C Stainless Steel: Features superior hardness and extreme abrasion resistance, with strong environmental adaptability to damp workshops and medium corrosive industrial conditions. It prevents bearing abrasion, jamming and rust aging during long-term operation, suitable for automated production equipment, hydraulic auxiliary systems, printing machinery and light chemical industrial facilities.
316 Stainless Steel: Premium corrosion-resistant grade with excellent salt spray, acid and alkali resistance, as well as high-temperature stability. It withstands severe corrosive and high-humidity working scenarios, making it the top choice for marine auxiliary equipment, sanitary food machinery, chemical test instruments and sterile medical industrial devices.
