51107 Thrust Ball Bearing | Premium Large Bore Single Direction Axial Bearings
The 51107 thrust ball bearing is a large-bore, high-load single-direction axial bearing belonging to the standard 5110 series. Engineered for heavy axial thrust and continuous industrial operation, this model features an enlarged inner bore and optimized internal rolling structure, offering higher load tolerance and structural stability than smaller 5110 series variants. Designed exclusively for unidirectional axial loads with no radial load capability, this open detachable thrust bearing supports multiple industrial material grades, delivering customized wear and corrosion resistance for heavy machinery and harsh operational environments.
51107 Thrust Bearing Structure And Key Performance
Constructed with a three-piece separable assembly including a precision shaft washer, housing washer and high-grade steel ball set, the 51107 thrust bearing enables tool-free installation, quick disassembly and straightforward routine lubrication. Its deepened precision-machined raceway evenly distributes concentrated axial pressure, effectively reducing rolling friction, mechanical vibration and long-term fatigue wear. The rigid open structure maintains consistent positioning accuracy under sustained heavy loads, making it a reliable core component for vertical shaft limiting, heavy lifting and fixed-axis rotating systems.
51107 Bearing Material Properties And Industrial Applications
High Carbon Chrome Bearing Steel (GCr15): The standard industrial material for 51107 heavy-duty thrust bearings, featuring exceptional compressive strength, outstanding anti-fatigue performance and superior wear resistance. It retains stable structural rigidity during long-duration heavy-load operation with minimal maintenance requirements and extended service life. Primarily used in heavy industrial machinery, vertical rotating shafts, construction lifting equipment, mining machinery and general heavy-load axial support systems.
304 Stainless Steel: Delivers reliable atmospheric oxidation and rust resistance, perfectly suited for humid, dusty and open-air working conditions. It maintains stable mechanical performance under standard heavy axial loads, serving as an economical anti-corrosion alternative for light industrial machinery, food auxiliary equipment, outdoor mechanical assemblies and low-corrosion industrial positioning parts.
420 Stainless Steel: Combines high surface hardness and structural toughness with mild chemical corrosion resistance, effectively resisting cyclic mechanical wear and weak medium erosion. It ensures smooth and stable operation under frequent start-stop and variable-load working cycles, ideal for heavy-duty precision instruments, industrial optical equipment and high-end electromechanical positioning systems.
440C Stainless Steel: Boasts ultra-high hardness and excellent abrasion resistance, with strong adaptability to damp workshops and moderately corrosive industrial environments. It prevents bearing jamming, premature wear and rust aging in complex working conditions, widely applied in heavy-duty automated production lines, hydraulic support equipment, printing machinery and light chemical industrial devices.
316 Stainless Steel: High-end corrosion-resistant material with superior salt spray, acid and alkali resistance, plus excellent high-temperature oxidation stability. It withstands extreme corrosive and high-humidity scenarios, making it the optimal choice for marine heavy-duty accessories, food sanitary processing machinery, chemical test instruments and sterile medical industrial equipment.
Core Advantages And Industry Application Scope
The 51107 single-direction thrust ball bearing stands out with large-bore compatibility, excellent heavy-load capacity, low-friction stable operation and flexible multi-material customization. Its detachable split structure simplifies daily maintenance and reduces operational costs. Widely applicable in heavy industrial automation, precision detection equipment, food processing, marine engineering and chemical industries, it provides durable, high-precision axial load-bearing and shaft positioning solutions for various large vertical mechanical systems.
