xiros® deep groove ball bearings xirodur® A500, specialist for heat & chemicals, reinforced cage material, stainless steel balls

xirodur® A500 | The specialist with up to 50% longer service life

The xirodur® A500 material is the specialist for high chemical and temperature resistance. In combination with the xirodur® F500 cage, this combination of materials covers applications with continuous service temperatures from -100°C to +150°C, is very resistant to strong acids and ensures significantly longer maintenance cycles.

Typical application areas:

• Semiconductor industry
• Chemical industry
• High temperature applications

Tech up:

• New reinforced cage material for up to 50% longer service life compared to A500 cages
• Continuous use temperatures of up to 150°C

Cost down:

• Significantly reduced maintenance intervals

Proof:

• xiros ball bearings are thoroughly tested

Sustainability:

• Environmentally friendly, no additional lubricants needed
• igus® supports the circular economy of plastics and is investing in chemical recycling. More at: igus.eu/sustainability

When to use it?

• At application temperatures from -100°C to +150°C 
• When strong chemicals are used

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 +60°C ▷ xirodur® C160
• If antistatic conductivity is required ▷ xirodur® F180
• If electrostatic dissipation is also required ▷ xirodur® F500

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
