Crossed roller bearings SX are bearings for high precision applications, whose dimensions conform to ISO dimension series 18 to DIN 616. They comprise outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and is held together by three retaining rings.

Crossed roller bearings are very rigid, have high running accuracy and are supplied with normal clearance, low clearance or preload. Preloaded bearings have the suffix VSP.

The bearing outer rings are easily fixed to the adjacent construction using clamping rings.

Crossed roller bearings series we made:

1. SX Series

2. XSU14- standard series 14, without gear teeth, lip seals on both sides;

3. XSU08- standard series 08, without gear teeth, lamellar seals on both sides;

4. XSA14- standard series 14, external gear teeth, lip seals on both sides

5. XSI14- standard series 14, internal gear teeth, lip seals on both sides

6. XA- with external gear teeth, lip seals on both sides

7. XI- with internal gear teeth, lip seals on both sides

8. XU- without gear teeth, lip seals on both sides

Materials: Chrome steel 100Cr6/GCr15SiMn

Sealing

The bearings are of an open design. The sealing arrangement can be designed anywhere within the adjacent construction.

Lubrication

SX bearings do not have an oil-based preservative but are greased; they can be lubricated using oil.

Operating temperature

Crossed roller bearings are suitable for operating temperatures from –30 °Cto +80 °C.

 Attentions:

The separable inner or outer ring is fastened in place using special rivets, bolts or nuts when delivered. When installing, pls do not disassemble it. Also, erroneously installing the spacer retainer will signigicantly affect the rotational performance of the system.

1. The joint between inner and outer rings may be misaligned when delivered. In that case, pls loosen the bolts and correct the alignment by using a plastic hammer before installing it into the housing;
2. Pls do not force onto the securing rivets or the bolts when installing or removing the crossed roller ring;
3. When mounting the flange, pls pay attention to the dimensional tolerances of the parts so that the inner and outer ring can be fixed firmly by the flange from the side.
