Split Self-Aligning Roller Bearing

1.Product Introduction: Self-aligning roller bearings with separable inner and outer rings, which can be installed without disassembling the shaft, and are suitable for large and heavy shaft systems.
2.Structure Type: The inner ring and outer ring are axially split (with bolt connections), with double-row spherical rollers + steel cage, and metal seals to prevent impurities.
3.Size Range: Inner diameter ranging from 100mm to 2000mm, outer diameter ranging from 200mm to 3000mm, width ranging from 50mm to 300mm.
4.Material: Inner ring / outer ring: GCr15SiMn (heavy-load with integral forging and then split), GCr15 bearing steel (conventional), rollers: GCr15 bearing steel, cage: steel.
5.Precision: P0/P6 level.
6.Common Inner Tapered Hole: Optionally with a 1:12 tapered hole (suitable for shaft diameters ranging from 100mm to 2000mm).
7.Application Fields: Large rolling mill roll shafts, mining machinery spindles, port super-heavy-duty equipment.
8.Key Inspection Items: Fitting degree of the split surface, bolt connection strength, radial load-bearing capacity, sealing integrity.

Product Description

Split Self-Aligning Roller Bearings for Heavy Industrial Applications

High-Load Capacity • Customizable Designs • 48-Hour Rapid Delivery

Split self-aligning roller bearings are engineered to solve critical challenges in heavy machinery. These bearings compensate for shaft misalignment (up to ±3°) while handling extreme radial/axial loads (500kN+), making them ideal for metallurgy, port equipment, and mining. Unlike traditional solid bearings, their split design allows quick installation and replacement without dismantling adjacent components—saving hours of downtime.

Key Features

  • Simplified Maintenance: Split self-aligning roller bearing designs allow for hassle-free assembly on oversized shafts (φ300mm–φ5000mm).
  • Self-Aligning: Automatically adjusts to ±2.5°–3° misalignment, reducing vibration and uneven roller wear by 40%.
  • Extended Lifespan: High-purity GCr15 steel construction achieves 50% longer fatigue life under extreme conditions.

FAQs

Q: How does the split design simplify bearing replacement in port cranes?
A: Our products bolt together around the shaft, eliminating the need to remove machinery components—cutting replacement time by 60%.

Q: Can you make bearings larger than φ5000mm?
A: Yes! We specialize in ultra-large split self-aligning roller bearings up to φ6500mm using modular forging.

Q: Do you offer IoT-enabled bearings?
A: Yes. Integrated sensors monitor vibration and temperature, alerting you to maintenance needs before bearing failures occur.
