xiros® deep groove ball bearings xirodur® C160, chemical-resistant, glass balls

xirodur® C160 | Low-cost chemical-resistant

The xirodur® C160 material has high chemical resistance at temperatures from 0°C to +60°C. In addition to good chemical resistance, the material has low media absorption. However, this is offset by higher wear and lower load absorption than xirodur® B180 and xirodur® A500.

Typical application areas:

• Food industry (plant cleaning with chemicals)
• Electroplating industry
• Semiconductor industry
• Vacuum applications
• Autoclave applications

When to use it?

• For applications from 0°C to +60°C
• When strong chemicals are used
• When low media absorption is needed (vacuum/autoclave)

When not to use it?

• If application temperatures are between -40°C and +80°C ▷ xirodur® B180
• When high chemical resistance is required at temperatures from -100°C to +150°C ▷ xirodur® A500
• If antistatic conductivity is required ▷ xirodur® F180

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
