Spherical Rollers

1.Product Introduction: It is the core component of self-aligning roller bearings. The spherical structure is suitable for the spherical raceway of the inner ring of the bearing, can compensate for installation deviations, and is used for bearing maintenance and customization.
2.Structure Type: Double spherical shape (the convex surface fits the inner ring raceway), with precision grinding on the surface and no ribs (suitable for self-aligning movement).
3.Size Range: Diameter 10 - 200mm, length 15 - 250mm (matched according to the bearing model).
4.Material: GCr15 bearing steel (conventional), GCr15SiMn (for impact-resistant and heavy-load applications), with a quenching hardness of HRC60 - 65.
5.Precision: P0/P6 level (matched according to the precision of the applicable bearing).
6.Common Inner Tapered Hole: There is no inner tapered hole (it is a bearing component, not a complete bearing).
7.Application Fields: Maintenance and replacement of self-aligning roller bearings, customized bearing production.
8.Key Inspection Items: Spherical roundness, surface roughness, fitting degree with the raceway, hardness.

Product Description

High-Performance Spherical Rollers for Heavy Industrial Applications

Precision, Durability & Fast Global Delivery

When your machinery faces extreme loads, high temperatures, or critical operations, our spherical rollers deliver unmatched reliability. At LUOYANG INNO, we’ve spent three decades perfecting these components for industries where downtime is not an option. Whether you need standard replacements or custom-designed spherical roller solutions, our components are engineered to handle heavy radial/axial stress while compensating for misalignment.

Quality & Lifecycle Support

Every spherical roller undergoes spectral steel purity analysis and ISO 683-17 heat treatment. We provide IoT-driven maintenance dashboards and on-site retrofitting support.

FAQs

Q: Can your spherical rollers handle 150°C environments?
A: Yes! Our heat-treated GCr15SiMn rollers retain hardness (HRC 60–65) even in high-heat metallurgical applications.

Q: What’s the lead time for non-standard spherical roller orders?
A: Most custom designs ship in 15–20 days; contact us for expedited options on oversized roller components.

Q: Do you provide IoT integration for spherical roller monitoring?
A: Absolutely. We equip rollers with sensors to track vibration, temperature, and load in real time.
