xiros® deep groove ball bearings xirodur® S180, all-rounder in black, glass balls

xirodur® S180 | The all-rounder in black

The widest range of polymer ball bearing applications is covered by xirodur® B180. However, if the "white" colour does not suit your application, for example the bearing is designed as a visible part, the material xirodur® S180 is the right one. This material offers almost identical technical specifications to xirodur® B180, but is not quite as wear-resistant. Its characteristic feature is the colour black, which also offers higher UV resistance than xirodur® B180. This also makes it perfect for outdoor use.

Typical application areas:

• Visible machine parts
• Guide rollers for labellers
• Automotive

When to use it?

• If the colour "black" is desired
• When a cost-effective all-rounder is required

When not to use it?

• If application temperatures are permanently below -40°C or above +80°C ▷ xirodur® A500
• When high chemical resistance is required at temperatures up to +60°C ▷ xirodur® C160
• If antistatic conductivity is required ▷ xirodur® F180
• If the bearing is to be installed in an automotive interior ▷ xirodur® S180LF (low fogging)

Tolerances and measurement system:

the tolerances for the inner and outer diameter depend on the installation size. These are often approx. ±0.05mm to the nominal size. The bearing rings are usually injection moulded and naturally have a certain ovality. Therefore, the caliper is used to measure 90° to the injection point (if available) over the entire width of the bearing. The dimensions and tolerances are designed in such a way that they fulfil a slight press-fit by hand when using a H7 holder and h6 shaft. An additional locating spigot using a circlip (shaft) and snap ring (housing) is recommended to prevent axial displacement.

Installation recommendation:

1. Housing (tolerance H7)

2. Front (balls visible)

3. Rear (cage visible)

4. Press-fit the ball bearing, front side first

5. Install shaft (tolerance h6) with chamfer

6. A locating spigot must be provided
