Features and Benefits

High Load Capacity

Roller elements distribute loads over larger contact areas compared to Roller Bearing Slewing Rings, allowing your equipment to handle heavier working loads without premature failure.

Improved Rigidity

This roller-type design provides strong resistance to deformation even under minimal loads, maintaining positional accuracy even in demanding applications.

Smooth Rotation

Precision-ground raceways and optimized roller profiles minimize grinding and vibration, diminishing vitality utilization and amplifying component life.

Integrated Adapt Options

Available with inside or outside Gears machined straightforwardly into the bearing ring, rearranging your drive framework plan and decreasing gathering complexity.

Effective Sealing

Multi-lip seals anticipate defilement entrance whereas holding oil, guaranteeing solid execution in dusty or damp environments.

Simplified Installation

Through-holes for mounting jolts are precision-positioned, permitting clear integration into your hardware structure.

Applications

· Construction Equipment: Excavators, tower cranes, mobile cranes

· Material Handling: Port cranes, ship loaders, gantry systems

· Mining Machinery: Bucket-wheel excavators, shovels, drilling rigs

· Metallurgical Equipment: Ladle turrets, continuous casters

· Industrial Machinery: CNC rotary tables, machining centers, welding positioners

· Marine Equipment: Deck cranes, offshore platforms

· Renewable Energy: Wind turbine yaw and pitch systems

Installation Guide

Pre-Installation Checks:

1. Verify mounting surfaces are clean, flat, and within specified tolerances

2. Check that bolt holes align properly with your support structure

3. Inspect seals and rolling elements for shipping damage

Installation Steps:

4. Position the bearing carefully using lifting equipment—avoid impact or dropping

5. Apply recommended lubricant to raceways before installation

6. Align bolt holes and insert fasteners hand-tight initially

7. Tighten bolts in a star pattern to the specified torque value

8. Verify smooth rotation by hand before connecting drive systems

9. Install protective covers if operating in contaminated environments

Important: Never strike the bearing directly. Always support the full circumference during handling.

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

Maintenance and Care

Grease Schedule:

Relubricate each 100-200 working hours, or quarterly for continuous-duty applications. Utilize lithium-based oil (NLGI Review 2) unless something else specified.

Regular Inspections:

· Check for bizarre clamor or vibration monthly

· Inspect seals for harm or wear each 500 hours

· Verify jolt torque quarterly, particularly in high-vibration applications

Long-Term Storage:

If putting away hardware for expanded periods, apply conservation oil and turn the bearing quarterly to redistribute grease.

FAQ

Q: What's the distinction between roller and ball slewing bearings?

A: Roller heading offer higher stack capacity and inflexibility, whereas ball orientation give smoother revolution at lower loads. Select based on your application requirements.

Q: Can you fabricate orientation to my particular dimensions?

A: Yes. We give custom plan administrations and can reproduce existing heading from tests or 2D drawings.

Q: What accuracy review ought to I specify?

A: P0 suits common mechanical utilize. P6/P5 fits accuracy apparatus. P4 is for high-accuracy applications like CNC equipment.

Q: Do you give establishment support?

A: We offer specialized meeting and establishment direction to guarantee appropriate fitment and performance.

Q: What's your normal lead time?

A: Standard sizes transport inside 2-3 weeks. Custom orientation require 4-6 weeks depending on complexity.

Q: How do I decide the rectify bearing size?

A: Give us with your stack necessities, revolution speed, and mounting imperatives. Our engineers will suggest the ideal setup.
