Start this model review from its shaft and ratio interfaces: EP-SPB 200-03 V-Belt Pulley combines a SPB three-belt groove set with pitch/datum diameter P 200 mm and outside diameter O 207 mm. The catalogue row pairs it with bush 2517 and maximum bore 60 mm.
This model sits in the mid-range diameter part of the range. That makes the most useful pre-order measurements the existing belt section, shaft diameter, center-distance context and the available outside/axial envelope. A correct bush number does not by itself prove that the pulley face and hub will clear the machine.
Engineering data for this configuration
The table is generated from the model metadata imported with this product, keeping the exact P/O, type, bush, maximum bore and construction dimensions together.

Where this model enters a drive decision
This model can appear in higher-capacity narrow V-belt drives. Buyers commonly start from larger pumps, compressors, material-handling systems and process machinery, then narrow the choice with the actual motor/driver speed, required driven speed and available shaft diameter. The application page is a starting context, not proof that one pulley fits every machine in that industry.
Installation and replacement checks
During replacement, compare the old and new pulley side by side before installing: belt section, groove count, hub projection, shaft/bush interface and outside envelope should all agree with the intended configuration.
Measure the shaft
Record shaft diameter and key arrangement before ordering the bush/bore combination.
Check ratio and clearance
Use P for ratio; use O and the face/hub dimensions for physical space.
Align the drive
Seat the pulley correctly before belt tension is applied and check both pulley faces.
Buyer questions for SPB three-belt pulleys
What should I quote for this exact model?
Use the EP- model above and include shaft diameter, quantity, application, driver speed and driven speed. Add a photo or drawing for replacement work.
Should I calculate with outside diameter?
Use the pitch/datum diameter for the theoretical pulley speed ratio. Outside diameter is mainly a physical-envelope check.
Can the bore be enlarged beyond the listed maximum?
Treat the listed maximum bore as the limit for this catalogue configuration. If the shaft is larger, select a different model/bush arrangement or request an engineering review.
