BT22ZPN - Phenolic Cotton/Linen Tube
BT22ZPN is similar to BT22NPN being composed of an extra-fine weave woven cotton fabric combined with a phenolic resin system. BT22ZPN tubes have higher densities (minimum allowable specific gravity is 1.30) resulting in enhanced precise machining characteristics and are expected to give longer life in wear applications. Typical uses include retainers for ball-bearings.
