Stacker-Reclaimer Slewing Bearing

Stacker-Reclaimer Slewing Bearing

When your bulk material handling system operates around the clock in demanding port or mining environments, you need a rotating component that won't fail. Our Stacker-Reclaimer Slewing Bearing delivers exactly that—engineered with 42CrMo4 high-strength alloy steel and precision manufacturing techniques to withstand extreme loads, continuous rotation, and harsh environmental conditions. Whether you're managing coal storage in power plants or handling iron ore in open-pit mines, this bearing provides the reliable rotational support your equipment depends on. With over 20 years of specialized experience, we understand what it takes to keep your stacker-reclaimer running smoothly.

Product Details

Stacker-reclaimer systems require bearings that can handle both heavy radial loads and significant overturning moments during operation. Our slewing bearings are specifically designed for these dual demands.

Construction and Design

The bearing features a raceway structure that distributes loads evenly across rolling elements. We manufacture these units in four configurations:

· Single-row four-point contact ball type for moderate loads

· Double-row ball type for enhanced load distribution

· Three-row roller type for maximum capacity

· Cross-roller type for compact installations requiring high rigidity

Each plan employments GCr15SiMn bearing steel for rolling components, guaranteeing steady hardness and wear resistance all through the bearing's benefit life.

Material Processing

The ring fabric experiences extinguishing and hardening to accomplish HB280-320 hardness. Raceway surfaces get acceptance solidifying treatment, coming to HRC55-60 to stand up to contact stretch and surface weakness. For establishments in coastal or saline situations, we apply heavy-duty anti-corrosion coatings that secure against natural degradation.

Why Choose Us?

Manufacturing Capability

Our office in Luoyang works CNC vertical machines, extinguishing machines, and adapt hobbing hardware competent of creating slewing heading from 50mm to 10,000mm in distance across. This extend covers most stacker-reclaimer applications, from compact yard Gear to large-scale harbour machinery.

Quality Systems

We keep up ISO 9001 certification and take after strict prepare controls. Each bearing experiences ultrasonic testing and attractive molecule review some time recently shipment. Facilitate measuring machines confirm dimensional precision, whereas vibration analyzers guarantee smooth operation.

Technical Support

Our designing group gives determination help based on your stack calculations and working conditions. We back establishment arranging and can make custom arrangements when standard items do not fit your application. If you have bequest gear without documentation, we offer turn around building administrations to make substitution orientation from your existing units.

Technical Specifications

Features and Benefits

High Stacking Capacity

The robust cross-section and optimized raceway geometry allow these bearings to support the combined weight of stored material and structural components while accommodating boom swing forces.

Continuous Operation Capability

Advanced heat treatment processes create consistent material properties that resist deformation under sustained loads. This stability ensures your equipment maintains critical alignment even during extended operating cycles.

Environmental Resistance

Protective coatings and advanced sealing systems exclude contaminants while retaining lubricant. This is vital when your equipment operates in dusty stockyards or salt-laden coastal environments.

Mounting Flexibility

Bolt hole patterns conform to standard configurations, simplifying installation and allowing direct replacement of worn units without modifying your existing base frame.

Applications

Your Stacker-Reclaimer Slewing Bearing finds use across bulk material handling sectors:

Port Facilities

Container terminals and bulk cargo terminals use these bearings in stacker-reclaimers that manage coal, iron ore, grain, and other commodities.

Mining Operations

Open-pit mines rely on large-capacity stackers equipped with our bearings to build and reclaim material stockpiles efficiently.

Power Generation

Coal-fired power plants use stacker-reclaimers for fuel yard management, where bearings must perform reliably in coal dust environments.

Steel Production

Raw material yards at steel mills depend on these bearings in equipment handling iron ore, coke, and limestone.

Testing & Certification

Every bearing batch receives:

· Dimensional verification using coordinate measuring equipment

· Material composition analysis confirming alloy specifications

· Hardness testing at multiple locations

· Non-destructive testing via ultrasonic and magnetic methods

· Rotation smoothness evaluation under simulated loads

Our company holds ISO 9001 certification. Items comply with RoHS prerequisites for material composition.

Installation Guide

Pre-Installation Checks

Verify that mounting surfaces are level and free from burrs. Check jolt gap arrangement some time recently situating the bearing. Affirm that your establishment can bolster the indicated jolt torque.

Positioning

Use lifting gear appraised for the bearing's weight. Adjust jolt gaps carefully—forcing jolts through misaligned gaps can misshape the raceway.

Fastening

Apply jolts in a star design, fixing slowly in stages. Utilize a calibrated torque torque to accomplish the indicated preload. Uneven fixing will make inner push and diminish bearing life.

Lubrication

Fill oil channels totally some time recently beginning operation. Pivot the bearing gradually whereas applying oil to guarantee indeed dissemination over the raceway.

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.

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

Lubrication Schedule

Relubricate every 100 operating hours under normal conditions. Increase the frequency in dusty environments or when operating temperatures exceed the specified range. Use a lithium-based grease suitable for heavy-load applications.

Inspection Points

Check for abnormal noise or vibration during operation—these indicate potential raceway damage or contamination. Inspect seals regularly and replace them if hardening or cracking is observed. Monitor mounting bolt preload (torque) quarterly.

Storage

If storing spare bearings, keep them in a dry environment. Apply a rust-preventive oil coating to machined surfaces. Rotate stored bearings quarterly to prevent false brinelling.

FAQ

Q: What's the ordinary lead time for custom sizes?

A: Standard plans inside our generation extend ordinarily dispatch inside 4-6 weeks. Complex customizations may require 8-10 weeks depending on specifications.

Q: Can you give heading for greatly destructive environments?

A: Yes. We offer upgraded coating alternatives and overhauled seal materials for establishments close seawater or chemical preparing areas.

Q: Do you supply mounting jolts with the bearing?

A: We give jolt details but regularly do not incorporate clasp. This permits you to source jolts coordinating your nearby measures and favored grades.

Q: How do I decide the right bearing sort for my application?

A: Send us your stack information, turn speed, and mounting measurements. Our engineers will suggest the fitting configuration.

Q: What guarantee scope do you offer?

A: We stand behind our fabricating quality. Contact Us to examine guarantee terms particular to your application and working conditions.
