P20 BASIC DIMENSIONS

P20 BUSH OPTIONS

The P20 bushes are available in metal or nylon; with three thread options; and with or without a locating feature:

Diecast Zinc Alloy
- M10 x0.75mm pitch (Type C)
- M10 x0.75mm pitch, with locator (Type CEBS)
- 9.52mm x32tpi (Type CBS)
- 9.52mm x32tpi, with locator (Type CBSL)
- M7 x0.75mm pitch (Type CG)
Glass Filled Nylon
- M10 x0.75mm (Type CP)

Do not attempt to prevent any unwanted body rotation by overtightening the retaining nut, since this can cause thread damage, distortion, change of electrical resistance and restrict shaft rotation. BS9130:1972 provides further details on this topic. The recommended torque for tightening the retaining nut is 45cNm and this can be achieved cost effectively by using a Torque Limiting device as shown on our Accessories page.
