Thrust Ball Bearing Large – Engineered for Heavy-Duty Axial Load Applications

For reliable heavy-duty axial load transmission, our Thrust Ball Bearing Large deliver proven stable performance. Designed with outer diameters ranging from 100 mm to 5,000 mm, these bearings withstand extreme axial loads for vertical pumps, wind turbines and shield tunneling machines.Manufactured from high-strength 42CrMo / 50Mn alloy steel with GCr15SiMn rolling elements, they are available in precision grades P0, P6, P5 and P4.Backed by over 20 years of professional engineering experience and ISO 9001 certification from Luoyang Hengguan Bearing, every large thrust ball bearing undergoes strict inspection to ensure stable operation under severe working conditions.

Thrust Ball Bearing Large Details

This type of rolling element bearing is specially engineered to support high unidirectional or bidirectional axial loads. It is widely adopted in scenarios dominated by vertical force, including large vertical pumps, marine propellers and crane slewing systems.

The standard structure consists of a Shaft washer (tight fit), housing washer (clearance fit), and high-precision ball and cage assembly. The modular design simplifies installation and daily maintenance, minimizing downtime and economic loss for large industrial equipment.

We supply custom large thrust ball bearings with diameters from 100 mm to 5,000 mm. Rich size flexibility allows accurate selection according to project demands, avoiding over-design and unnecessary cost waste

Technical Specifications

Features and Benefits

Separable Design

Shaft washers and housing washers are fully separable for easy disassembly. It simplifies daily maintenance and reduces downtime for vertical pump stations and gearbox equipment.

High Load Capacity

Constructed from premium 42CrMo and 50Mn alloy steel, the bearing withstands extreme axial loads without deformation. It keeps equipment stable and balanced even under peak operating pressure.

Precision Rolling Elements

GCr15SiMn steel balls feature a minimum hardness of HRC 60 and Grade 100 precision. This ensures low vibration, quiet operation and extended service life.

Wide Size Range

Available in outer diameters from 100 mm to 5,000 mm, perfectly matching shield tunneling machines, wind turbine yaw systems, marine thrusters and other large equipment with zero compromise.

Multi-Grade Precision

Select P0 for general industrial use, or specify P4 for applications requiring ultra-tight tolerances. You only pay for the precision your project actually needs.

Corrosion Resistance

Optimized heat treatment and premium material selection provide reliable protection against moisture and chemical exposure, suitable for harsh working conditions such as offshore platforms and hydropower stations.

Applications

Our thrust ball bearing large products excel in heavy industrial applications where axial load bearing performance is critical. Construction machinery relies on these bearings for excavator swing mechanisms, crane turntables and heavy lifting equipment. Energy sector applications include wind turbine yaw systems, hydroelectric generators and industrial turbomachinery.

Manufacturing facilities adopt these bearings in heavy-duty presses, rolling mills and large rotating machinery. The mining industry depends on them for conveyor systems, crushers and extraction equipment, where long-term reliability is non-negotiable.

Installation Guide

Correct installation ensures optimal performance and extended bearing service life. Thoroughly clean all mating surfaces and inspect for damage or abnormal wear. Verify shaft and housing tolerances meet technical specifications before assembly.

Use professional lifting tools for large-diameter bearings. Apply a thin, uniform film of recommended grease to all contact surfaces. Install the bearing correctly with standard tools to avoid damage to raceways and rolling elements.

Check alignment strictly and confirm proper internal clearances. Follow standard torque values for mounting bolts, and ensure sufficient lubrication before official operation.

Exhibition

We attend many famous international exhibitions such as Shanghai International Maritime Exhibition,Mining World Russia, bauma China, CTT Russia, etc

Partners

Your trust, we cherish in heart all times and will reciprocate that trust with unwavering quality.

Testing & Certification

Every bearing passes through our quality control process:

· Coordinate Measuring Machines verify dimensional accuracy

· Vibration Testers catch imbalance issues before shipment

· Life Testing Machines simulate years of operation in compressed timeframes

We maintain ISO9001 certification and ensure RoHS compliance for European markets. Full traceability from raw material to finished product gives you audit-ready documentation.

Maintenance and Care

Lubrication

Reapply grease every 500–1000 operating hours depending on load and speed. Use lithium-based EP2 grease or ISO VG 220 oil for circulating systems.

Inspection

Monitor vibration levels monthly. Rising readings indicate wear or contamination. Check for unusual noise during routine operation.

Cleaning

If disassembled, clean all components with petroleum solvent. Avoid abrasive methods that damage precision surfaces.

Storage

Store in a dry, temperature-controlled environment. Apply rust preventive if inactive for over six months.

FAQ
