/ Spherical roller bearings

Spherical Roller Bearing

1.Product Introduction: General-purpose self-aligning roller bearings, with a double-row spherical roller structure, bearing radial loads, capable of compensating for installation deviations, and widely used in industrial applications.
2.Structure Type: The inner ring has a spherical raceway, the outer ring has double ribs, with double-row rollers + stamped steel / brass cage, and it is open / sealed.
3.Size Range: Inner diameter 20 - 1000mm, outer diameter 47 - 2000mm, width 16 - 300mm.
4.Material: Inner ring / outer ring: GCr15 bearing steel (conventional), 42CrMo (for heavy-load models), rollers: GCr15 bearing steel, cage: stamped steel / brass.
5.Precision: P0/P6 level.
6.Common Inner Tapered Hole: For inner diameters ≥ 50mm, a 1:12 tapered hole can be optionally selected, and for large inner diameters (≥ 200mm), the tapered hole is a standard configuration.
7.Application Fields: Electric motors, reducers, construction machinery, rolling mills, port equipment.
8.Key Inspection Items: Self-aligning performance, radial load-bearing capacity, dimensional accuracy.
