For radial bearing loads up to 500 N In aluminium or stainless steel 1.4305/1.4404 Various shaft versions available Including fastening material Simple installation thanks to integrated play- free claw coupling For encoders with clamping flange Ø58 other flange designs on request Replaces in combination with the mounting bracket MW the bearing block LB

Design and functionThe ZHF pre-flange enables bearing loads of up to 500 N radially and 250 N axially, and protects the rotary encoder's bearing against overloading. To do this, it is simply mounted on the existing rotary encoder flange. A play-free coupling ensures the connection between the rotary encoder shaft and pre-flange shaft.

The pre-flange is manufactured from seawater-proof alumini-um or stainless steel (1.4305 or 1.4404). The double moun-ting consists of two ball bearings sealed on both sides (2RS bearings). The coupling elements required for connection to the rotary encoder shaft are part of the scope of delivery. In combination with mounting angle MW-x-02 (data sheet MZ10111), the ZHF is compatible with the bearing bracket LB-01, LB-05 or LB-07.

Technical data Operating speed: 10,000 rpm max. Moment of inertia (rotor): 30 gcm² Operating torque: ≤ 5 Ncm (at 20 °C) Starting torque: ≤ 4 Ncm Perm. shaft load: 500 N radially 250 N axially Bearing service life: > 108 revolutions Weight: Approx. 0.4 kg (aluminium) Approx. 0.7 kg (stainless steel) Operating temperature range: - 40 °C to + 85 °C Storage temperature range: - 40 °C to + 85 °C

* The basic versions according to the data sheet bear the number 01. Deviations are identified with a variant number and are documented in the factory.
