High Precision Crossed Roller Bearing (XSU SERIES)

XSU Series Crossed Roller Bearings

(Integrated Inner/Outer Ring Type, both for inner-ring rotation and outer-ring rotation)

XSU series crossed roller bearings also known as turntable bearing without tooth. The inner and outer rings are equipped with mounting holes. The mounting holes can be countersunk or bolted holes. The outer diameter of the outer ring can be equipped with lubricating nozzles. Rubber seals can be installed on both sides of the bearing, this type of bearing has 2 types of dimension series, XSU08 series inner diameter range is Φ130~Φ360mm, XSU14 series inner diameter range is Φ344~Φ1024mm. 

Since the mounting holes are provided, this model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure. This model can be used for both inner-ring rotation and outer-ring rotation.

Installation Procedure:

1. Thoroughly clean the housing and other parts to be installed, and check to determine if deburring is required.

2. Since the Cross-Roller Ring is a thin-wall bearing type and therefore tends to misalign when it is installed, in ease of this situation, gradually drive the product into the housing or onto the shaft by gently hitting it with a plastic hammer, while keeping the product horizontal. Taking care, continue to hammer until it fully contacts the reference surface.

3. Place the presser flange onto the Cross-Roller Ring. Rock the flange several times to match the bolt holes.

4. Insert the presser bolts into the holes. Manually turn the bolts and make sure they do not display skewing caused by misalignment of the holes.

5. Tighten the presser bolts in three to four steps from light to full tightening by repeatedly securing the bolts in diagonal order. When tightening (he separable inner or outer ring, slightly turning the integral outer or inner ring will correct the dislocation between the ring and the body.
