With over 20 years of manufacturing expertise and ISO 9001 certification, our specialized bearings cover diameters from 200 mm to 2000 mm with precision grades from P0 to P4. Each unit features a 45° contact angle single-row ball structure optimized for simultaneous axial, radial, and moment loads. Our raceway grinding accuracy reaches 0.005 mm, while Gear teeth achieve ISO Grade 6 precision. Manufactured from 50Mn or 42CrMo alloy steel rings with GCr15 bearing steel balls, these components deliver reliable performance in high-speed rotary fillers, automated palletizers, and orbital wrappers across food, pharmaceutical, and industrial packaging lines.

Packaging Machine Slewing Bearing Details

Our product serves as the rotational core in automated packaging systems. The compact design integrates mounting holes and optional gear teeth directly into the bearing rings, simplifying machine assembly and reducing equipment footprint.

Structural Design

The single-row ball configuration adopts a precisely calculated 45° contact angle. This geometry ensures optimal load distribution against axial, radial, and tilting moment forces simultaneously. The raceway undergoes super-finishing to maintain dimensional accuracy within 0.005 mm, minimizing friction and vibration during high-speed rotation.

Load Capacity

Our bearings reliably handle the demanding conditions of 24/7 production scenarios. The high-strength alloy steel rings withstand repeated acceleration and deceleration cycles common in rotary filling equipment operating over 60,000 bottles per hour.

Sealing System

Nitrile rubber (NBR) seals protect internal components from dust, packaging debris, and cleaning agents. This design extends service intervals and reduces unplanned downtime on your production line.

Technical Specifications

Features and Benefits

Low Friction Grinding Design

The precision-ground raceway reduces rotational resistance. You will achieve lower energy consumption in continuous-operation packaging lines, effectively cutting your operating costs.

High Positioning Accuracy

Gear teeth machined to ISO Grade 6 ensure repeatable angular positioning. This precision prevents label misalignment in high-speed labeling modules and maintains consistent fill volumes in rotary fillers.

Extended Service Life

Stress-relief heat treatment stabilizes ring geometry under cyclic loading. Hardened GCr15 steel balls resist surface fatigue, allowing your equipment to maintain accuracy between scheduled maintenance intervals.

Vibration Damping

The optimized ball complement and cage design minimize resonance during frequent start-stop cycles. This results in smoother operation of rotary tables in blister packaging machines and tube filling equipment.

Contamination Resistance

Effective sealing keeps out flour dust in food packaging, powder residue in pharmaceutical production, and paper fiber debris in carton packaging systems. It greatly reduces bearing failures caused by abrasive contamination.

Applications

Food Packaging Machinery

• Rotary filling platforms for bottling lines
• Vertical form-fill-seal machines for snack foods
• Sealing stations in ready-meal production lines

Pharmaceutical Packaging Equipment

• Blister pack forming and sealing systems
• Cartoning machines requiring precise product positioning
• High-speed labeling equipment for regulatory compliance and product traceability

Daily Chemical Product Packaging

• Tube filling and sealing machines for cosmetics
• Rotary liquid filling tables for personal care products
• Capping systems requiring precise torque control

Industrial Product Packaging

• Automated case packing systems for consumer electronics
• Robotic palletizing cells at the end of production lines
• Orbital stretch wrappers for pallet load stabilization

The packaging machine slewing bearing in these applications handles the complex load patterns created by asymmetric product weights, rapid indexing movements, and continuous operation schedules.

Testing & Certification

Every slewing bearing undergoes comprehensive quality testing using advanced equipment:

• Coordinate Measuring Machines verify dimensional accuracy
• Vibration Testing confirms smooth rotation characteristics
• Hardness Testing ensures proper heat treatment
• Gear Inspection validates slewing ring gear precision
• Life Testing validates durability under simulated operating conditions
• Material Certification provides full traceability

ISO 9001 certification and RoHS-compliant materials ensure your slewing ring meets international quality standards.

Installation Guide

Pre-Installation Inspection

Verify mounting surface flatness using a precision straightedge. Surface deviation should not exceed 0.1 mm across the bolt circle diameter. Clean all mounting surfaces to remove protective coatings, oil, and debris.

Mounting Procedure

1. Position the bearing on the lower mounting surface, aligning bolt holes
2. Apply thread-locking compound to mounting bolts per equipment specifications
3. Tighten bolts in a star pattern to the specified torque value
4. Recheck bolt torque after initial equipment operation (first 8–24 hours)

Gear Mesh Alignment (if equipped)

Adjust the pinion position to achieve proper backlash—typically 0.2–0.4 mm for packaging machinery applications. Use feeler gauges to verify consistent spacing around the full rotation.

Lubrication

Apply the specified grease type to the raceway through provided ports. Avoid over-greasing, which can cause elevated operating temperatures and seal damage.

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

Regular Inspection Schedule

· Weekly: Check for abnormal noise or vibration during operation

· Monthly: Verify gear mesh backlash and inspect seals for damage

· Quarterly: Measure bearing clearance and re-lubricate per service intervals

Lubrication Intervals

Standard recommendation: Every 500 operating hours or 3 months, whichever occurs first. Harsh environments (dusty, high-temperature, or frequent washdown) may require shorter intervals.

Bolt Torque Verification

Re-torque mounting bolts quarterly during the first year of operation. Loose bolts cause fretting damage to mounting surfaces and accelerate bearing wear.

Warning Signs

Contact our technical support if you observe increased rotational resistance, grinding sounds during indexing, or visible seal deterioration. Early intervention prevents secondary damage to your packaging equipment.

FAQ

Q: What precision grade should I specify for a rotary filler running at 60,000 BPH?

A: We recommend P5 precision for applications exceeding 40,000 BPH. This grade maintains positioning accuracy under high-speed rotation, preventing product spillage and cap application errors.

Q: Can your bearings withstand frequent washdown procedures in food processing?

A: Yes. Our NBR seals resist water and standard cleaning agents. For high-pressure, high-temperature washdown environments, we offer upgraded seal configurations. Discuss your specific cleaning protocols with our engineers.

Q: Do you provide bearings with integrated encoders for position feedback?

A: We manufacture bearings with mounting provisions for aftermarket encoders. For integrated solutions, our engineering team can design custom modifications based on your control system requirements.

Q: What is the typical lead time for a custom bearing design?

A: Standard customization (modified dimensions, special gear modules) typically requires 4–6 weeks after drawing approval. Complex modifications may extend to 8–10 weeks. We maintain stock of common sizes for immediate shipment.

Q: How do I calculate the required bearing size for my new packaging machine?

A: Provide our team with your equipment's payload weight, rotation speed, indexing frequency, and available mounting space. We'll perform load calculations and recommend appropriate bearing specifications.
