Accuracy classes

Accuracy classes of PG series are classified into:

  • - normal (C),
  • - high (H),
  • - precision (P),
  • - super precision (SP),
  • - ultra precision (UP).

The choice depends on the equipment requirements.

Preload

There are three types of standard preload for different application conditions.

Class Code Preload Examples of application
Light preload Z0 0-0.02C Certain load direction, low impact, low precision required
Medium preload ZA 0.05C-0.07C Low load and high precision required
Heavy preload ZB 0.10C-0.12C High rigidity required, with vibration and impact
