*Bore diameters other than the standard bore diameters given above are also possible. d max indicates the maximum bore diameter with a round shaft.

*In addition to round bores, key processing can also be handled. Consult Miki Pulley for details.

*Dimensions, mounting and the like are not interchangeable with other BXW models.

Options of BXW Models

Dust Covers

There are dust covers available as optional parts. These dust covers can be used to prevent dust and other foreign particles from entering into the parts, enabling the unit to be used in harsher work environments.
There are two types of dust covers to choose from, one without bores drilled into it for the shaft through-holes that can be used to provide full cover and one with bores drilled into it for the shaft through-holes that can be used with the shaft inserted into the brake. There are also options for the positions of lead wire connecting bores, using either a plate-mounting position or a stator-mounting position for mounting the brake.

[Specifications]

Material	Ethylene propylene diene monomer (EPDM) rubber
Temperature range	-40°C to +140°C
Exterior color	Black
Applicable brake models	L type, H type, S type BXW models
Applicable brake sizes	#01, #02, #03, #04, #05
Applicable specification voltages	12 V DC, 24 V DC, 45 V DC, 90 V DC 180 V DC

*The temperature range listed is for the dust cover material. The overall operating temperature range for BXW models is from -10°C to +40°C.

*This part cannot be used with BXW models that come with release levers and R type BXW models.
