Cross Roller Bearing

1. RA cross roller bearing is outer Ring separable type and inner ring rotation design.
2. Sizes:Inner Diameter: 20-350mm Outer Diameter: 70-540mm Width: 12-45mm
3.Performance Advantages:High radial, axial and moment load capacity in a single bearing; low friction coefficient for smooth rotation; excellent runout accuracy.
4.Material: Gcr15, Gcr15SiMn.
5. Application: Joints or rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical machines, measuring instruments, IC manufacturing devices, etc.
6. Accurcy: P6, P0, P5, P4, P8.

Product Introduction: It can bear radial + single - direction axial combined load, with a contact angle of 10° - 30°, suitable for medium - light load scenarios.
2.Structure Type: The inner ring has a tapered raceway, the outer ring is separable, with a single - row of rollers + cage, and it is open - type (dust cover is optional).
3.Size Range: Inner diameter 10 - 500mm, outer diameter 26 - 1000mm, width 8 - 200mm.
4.Material: Inner ring/Outer ring/Rollers: GCr15/GCr15SiMn/20Cr2Ni4A, cage: stamped steel / brass.
5.Precision: P0,P6,P5
6.Application Fields: Automobile hubs, reducers, machine tool spindles (positioning end), agricultural machinery gearboxes.
7.Key Inspection Items: Taper surface fitting degree, radial / axial load - bearing capacity, dimensional accuracy.

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 360mm, outer diameter 540mm, width 134mm.
4.Material: Inner ring / outer ring: GCr15 bearing steel (conventional), 42CrMo (for heavy-load models), rollers: GCr15 bearing steel, cage: stamped steel / brass.
