Split Cylindrical Roller Bearing

1.Product Introduction: The inner ring / outer ring can be split, allowing installation without disassembling the shaft, suitable for large / heavy shaft systems.
2.Structure Type: The inner ring / outer ring are axially split (with bolt connections), with single-row / double-row rollers + cage, and metal seals.
3.Size Range: Inner diameter 100 - 1500mm, outer diameter 200 - 2000mm, width 50 - 300mm.
4.Material: Inner ring / outer ring / rollers: GCr15/GCR15SIMN/20Cr2Ni4A, cage: stamped steel / brass.
5.Precision: P0/P6 level, P5 level for large precision equipment.
6.Application Fields: Rolling mill roll shafts, large electric motor rotors, mining machinery spindles, port crane large shafts.
7.Key Inspection Items: Split surface fitting degree, bolt pre-tightening force, radial clearance, axial positioning accuracy.

Product Description

Revolutionizing Maintenance with Split Cylindrical Roller Bearings

Split cylindrical roller bearings eliminate the need for complete shaft disassembly during installation or replacement—a game-changer for industries like wind energy, mining, and paper production. Engineered for hard-to-access equipment, these bearing products combine axial split rings with optimized roller arrangements. Whether you're maintaining a crusher or retrofitting a legacy machine, our split bearing design reduces downtime by up to 70%.

Key Advantages

  • Maintenance Efficiency: Split architecture allows swift replacement of split cylindrical roller bearings without removing connected drives or gears.
  • Extreme Conditions: Designed for 500℃ heat resistance and 300MPa shock load tolerance in heavy bearing applications.
  • Rapid Logistics: 1,000+ standard split roller bearing models ready for 48-hour global dispatch.

Industry-Proven Applications

  • Wind Turbines: Ceramic-coated split roller bearings withstand salt spray corrosion with dynamic load ratings ≥800kN.
  • Mining Crushers: Carburized steel rollers endure abrasive dust and extreme impacts, extending bearing replacement cycles.
  • Paper Mill Dryers: PTFE seals block steam ingress at 150℃ in high-moisture bearing operating environments.

Quality & Lifecycle Support

Every bearing undergoes 12-stage quality control, including load, noise, and endurance testing. We provide 3D modeling and IoT-driven wear analysis for complete lifecycle management.

FAQs

Q: Can you create split cylindrical roller bearings for obsolete machinery?
A: Absolutely. 87% of our projects involve reverse-engineering legacy bearing systems within short lead times.

Q: Do you offer emergency delivery for large split bearings?
A: Yes—critical bearing orders ship within 48 hours, even for φ2000mm split units.

Q: What certifications do your roller bearing products have?
A: All bearings meet ISO 9001, CE, and API 6D standards, with DNV GL certification for our wind bearing series.
