R4002-ID10 – Flexure Pivot Bearing (Double-Ended)

Type: Precision flexure pivot

Order No.: R4002-ID10

Origin - china

Delivery - 8 weeks

Description:

The R4002-ID10 is a high-precision, double-ended flexure pivot bearing designed for applications requiring zero friction, no lubrication, and maintenance-free angular motion. It provides smooth, repeatable rotation around a fixed axis using a flexing stainless-steel element — ideal for precision mechanisms where conventional bearings are not suitable.
