Roller Slewing Bearing

Roller Slewing Bearing - Heavy-Duty Rotating Solution for Industrial Applications

Product Details

When your equipment requires reliable rotation under extreme loads, Roller Slewing Bearing  provide the performance you need. Unlike traditional ball slewing bearings, our products utilize cylindrical or conical rollers as rolling elements, achieving superior load distribution across the raceway surface. This design allows them to withstand axial, radial, and moment loads simultaneously, making them indispensable components in cranes, excavators, tunnel boring machines, and other heavy machinery where any failure is unacceptable.

Luoyang Hengguan Bearing Technology Co., Ltd. manufactures bearings with diameters ranging from 100 mm to 10000 mm. Located in Luoyang, the heart of China's bearing industry, our manufacturing facility combines thirty years of engineering experience with advanced CNC machining centers and precision grinding equipment. Every bearing undergoes rigorous dimensional inspection and performance testing before leaving the factory.

The core advantage lies in the roller contact mechanism. The cylindrical or conical rollers create line contact with the raceway, distributing stress more effectively than the point contact of ball bearings. This results in higher load capacity, lower contact stress, and longer service life in demanding applications.

We offer four structural configurations: single-row, double-row, triple-row, and cross-roller arrangements. Your choice depends on load characteristics, rotational speed, and space limitations. Our engineering team can assist you in selecting the optimal design for your specific application.

Technical Specifications

Features and Benefits

High Load Capacity

The roller elements and raceways form line contact, distributing the load over a larger surface area. Compared to ball bearings of similar size, this design can withstand greater radial and axial forces, which is crucial for cranes and heavy excavators weighing thousands of tons.

Superior Shock Resistance

The robust roller geometry is designed to absorb impact loads without undergoing plastic deformation. This ensures reliable operation of your equipment, even under the sudden load changes commonly encountered in material handling and mining applications.

Precision Rotation

The raceways are machined using CNC grinding technology with strict dimensional control, ensuring smooth bearing operation and minimal oscillation. This high-precision machining reduces vibration transmission to the connected structure and extends the service life of adjacent components.

Versatile Load Handling

Single-row bearings primarily handle axial or radial loads. Double-row and triple-row bearing configurations can withstand complex combined loads and overturning moments, making them ideal for applications such as ship loaders and steel mill converters.

Extended Service Life

High-purity bearing steel and advanced heat treatment processes create hard and wear-resistant raceways. With proper lubrication, their service life can exceed 20,000 hours in typical industrial environments.

Simplified Installation

The pre-drilled mounting holes match standard bolt hole patterns. The split-ring design (where applicable) allows for installation without disassembling surrounding machinery, thus reducing downtime during maintenance or replacement.

Applications

Construction Machinery

Mobile cranes, tower cranes, crawler cranes, large excavators, concrete pumps, and drilling rigs rely on Roller Slewing Bearing assemblies for boom rotation and platform slewing.

Fabric Dealing with Equipment

Ship loaders, unloaders, stackers, reclaimers, and harbour cranes utilize these heading to turn overwhelming loads through monotonous cycles in cruel open air environments.

Tunneling and Mining

Tunnel boring machines (TBM) require large-diameter slewing rings to back cutter heads and encourage directional directing through shake formations.

Steel and Metallurgy

Converters, scoop turrets, ceaseless casting machines, and rolling plants join heavy-duty roller orientation for exact rotational situating beneath extraordinary temperatures.

Renewable Energy

Wind turbine yaw and pitch frameworks utilize slewing orientation to arrange nacelles and alter edge angles—applications where unwavering quality straightforwardly impacts vitality production.

Entertainment Equipment

Large perception wheels, turning stages, and entertainment rides depend on smooth, secure revolution given by precision-manufactured slewing rings.

Testing & Certification

Every bearing experiences dimensional confirmation utilizing facilitate measuring machines (CMM) to affirm raceway geometry and mounting gap positions. Vibration testing distinguishes any lopsidedness or surface inconsistencies some time recently shipment.

Our quality administration framework holds ISO 9001 certification, and all items comply with RoHS natural measures. Full fabric traceability documentation goes with each arrange, recording warm treatment parameters and assessment results.

Installation Guide

Pre-Installation Checks

Verify that mounting surfaces are level, clean, and free from burrs. Check jolt gap arrangement between the bearing and mating flanges.

Positioning

Lift the bearing utilizing fitting fixing connected to assigned lifting focuses. Adjust mounting gaps carefully—misalignment causes uneven stack dispersion and untimely wear.

Fastening Sequence

Install jolts in a star design, fixing slowly in stages. Apply indicated torque values per establishment drawing. Utilize calibrated torque torques and bolt washers or thread-locking compound as required.

Lubrication

Fill the bearing with suggested oil through oil fittings some time recently operation. Turn the bearing a few transformations to disperse oil equally over raceways.

Final Inspection

Check for smooth turn without official. Confirm equip work (on the off chance that pertinent) and seal astuteness some time recently putting gear into service.

Exhibition

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

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

Packaging & shipping

Your goods are unique, and their journey should be flawless. Therefore, we offer professional and customized packaging services. Our experienced team will evaluate your goods' characteristics, transportation route, and environmental requirements to recommend the most secure solution, such as: wooden crate packaging, sturdy frame packaging, or composite reinforced packaging (wooden crate + iron frame).

Maintenance and Care

Regular Lubrication

Re-lubricate each 100-500 working hours depending on stack, speed, and natural conditions. Utilize lithium-based or polyurea oil with EP added substances reasonable for overwhelming loads.

Periodic Inspection

Examine seals for harm or wear each 1,000 hours. Check mounting jolt torque after beginning 50 hours of operation, at that point each 2,000 hours thereafter.

Contamination Prevention

Keep mounting surfaces and adapt teeth clean. Supplant harmed seals instantly to avoid entrance of water, tidy, or rough particles.

Rotation Monitoring

Listen for unordinary commotion amid operation. Expanded contact or sporadic revolution demonstrates potential issues requiring prompt inspection.

Storage Guidelines

Store unused heading evenly in a dry environment. Apply additive oil to machined surfaces and seal with moisture-proof wrapping.

FAQ
