1313 Bearing

1.Product Introduction: The double-row model of self-aligning ball bearings (1313), with an inner diameter of 65mm and a double-row steel ball design. Its radial load-bearing capacity is 1.8 times that of the single-row ones, suitable for medium load scenarios.
2.Structure Type: Inner ring (with cylindrical hole) + outer ring (with spherical raceway) + double-row steel balls + engineering plastic cage. An isolation ring is set in the middle to prevent collisions.
3.Size Range: Inner diameter: 65mm, outer diameter: 140mm, width: 33mm.
4.Material: Inner ring / outer ring: GCr15, rolling elements (steel balls): GCr15, cage: engineering plastic, isolation ring: GCr15.
5.Accuracy: Conventional P0 grade, precision models are of P6 grade.
6.Application Fields: Medium-sized water pumps (5.5kW), fans (10kW), textile equipment (carding machines), reducers (medium load).
7.Key Inspection Items: Consistency of double-row steel ball clearance (deviation ≤ 0.003mm), inner diameter accuracy (65 ± 0.008mm), running stability.

Product Description

1313 Bearing for Heavy-Duty Industrial Applications
