H BUSHED BORE SINGLE GROOVE PULLEY Brand new. Fractional HP, single groove, cast iron pulley. Use with a H-type split taper bushing (sold separately). For use with type "A" and "B" belts. Fully balanced.
Outside Diameter 18.75"
Belt Type A (1/2") Datum Diameter 18.00"
Belt Type B (5/8") Datum Diameter 18.40"
Shpg. 15 lbs.
Outside Diameter Diameter measured at the outside of the pulley.
Datum Diameter The datum diameters are an industry standard reference point used for calculations such as center distance and belt length. The datum system replaces the pitch system for classical belts and pulleys to compensate for differences in manufacturers construction of belts.(Click here to see the corresponding H bushings)
Is it possible to get a bushing to enable mounting the 18.75", #1-BKH 190 pulleys onto a 1 15/16" diameter shaft?
A: It is not physically possible with the H series bushings. A larger size of quick-detach hub/pulleys would need to be used.

Could you recommend a bearing to fit this pulley that would accept a 1 1/4 shaft?
A: No. The existing bore is tapered for an H-bushing, and would need to be machined out to accept any standard press-in bearing. That being the case, it would be the end-user's preference.

the belt does not have to fit tight on the pulley for the sawmill, just has to be tight enough to not come out easy
A: Item 13-B57 (60" on the back) appears to work as described. It can be rolled in by hand with some effort, and seats well enough it would require significant forces to dislodge it.

I'm building a sawmill and want to use the 18.75 pulleys as bandwheels. l need to figure out what size belt will fit snug on that pulley. Thank you
A: The outer circumference of this pulley is 58.875". A 5/8" v belt that is 59" on the outside may be too loose, and a belt that is 58" on the outside may be impossible to roll on.

will item no BK-H190 work with a 18 hp gas engine?
A: The maximum speed on these pulleys is 1325 rpm when the material constraints and rim speed are accounted for. Use over that speed is not recommended. While the smaller diameter pulleys have been used by customers on horsepowers that high, we do not remember one this size being used with that power.

what does fractional hp mean on bandwheel discription mean?
A: Fractional hp is commonly understood as motors up to 5 hp, generally. Some manufacturers define it strictly as motors of 1 hp or less, while many others allow anywhere from 3 to 5 hp in the definition. With pulleys of this diameter, rim speed limitation is also a consideration.

Hi... 1) I am looking for a v belt pulley for a bandsaw mill... is the 18.75" a heavy balanced pulley? 2) what size v belt would be a tight fit for this pulley? 3) what is the bore diameter? 4) what would be the shipping cost for 2 of these to Maine 04619
A: Yes, these pulleys are balanced. If you mean what size belt will fit tightly in the groove around the full diameter of the pulley, we do not know. This is a tapered bore pulley for use with H-bushings; you choose the bore size. Shipping for two to that zip code would be about $29.
