Atlas Copco Air Motors

Brakes LPB 05/15/25/35 for LZL 05/15/25/35
The brakes are assembled on the output side of the motors and
the output side of the brakes has the same flange and shaft
dimensions as the motors. They can be used either together
with bare LZL motors or together with LZL plus BG gears. The
brakes are activated by springs and released by air pressure and
they can hold at least the min. starting torque. The brakes are
intended for holding or emergency use but not as dynamic brakes.
LPB brakes are handled as accessories to the motors with
separate product numbers so they shall be ordered together
with a motor number and the assembly number 8990 0003 00.
Please see to that these orders are not mixed with other products.
