XSU Series Crossed Roller Bearings

XSU Series Crossed Roller BearingsXSU series crossed roller bearings, also known as turntable bearing without a tooth. The inner and outer rings are equipped with mounting holes. The mounting holes can be countersunk or bolted. The outer diameter of the outer ring can be fitted with lubricating nozzles. Rubber seals can be installed on both sides of the bearing, this type of bearing has two kinds of dimension series, the XSU08 series inner diameter range is Φ130~Φ360mm, and the XSU14 series internal diameter range is Φ344~Φ1024mm.This model can be used for both inner-ring rotation and outer-ring rotation. 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.

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 installed, for 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 ensure they do not display skewing caused by the misalignment of the holes.5. Tighten the presser bolts in three to four steps from light to complete tightening by repeatedly securing the bolts in a diagonal order. When drawing (the separable inner or outer ring, slightly turning the integral outer or inner circle will correct the dislocation between the ring and the body.
