EP-SPB 160-02 V-Belt Pulley is an exact SPB twin-belt configuration with P 160 mm, O 167 mm, bush 2012 and a listed maximum bore of 50 mm. This is a compact-diameter choice in the SPB family, so tight machine envelopes and higher shaft speed sensitivity.
At this compact-diameter size, the ratio calculation should use P rather than O. O remains important for the guard and nearby structure, while the twin-belt face means a compact step up in belt capacity without a wide pulley bank. Check the row-specific E/F/J/K/L/M/N dimensions if an existing hub, shoulder or guard sits close to the pulley.

Where this model enters a drive decision
In application discussions this geometry is most relevant to fans, pumps and machine auxiliaries that need two matched belts. The wider SPB use context also includes larger pumps, compressors, material-handling systems and process machinery; however, the suitability of this exact model depends on power, speed, wrap, duty cycle and shaft loading rather than industry name alone.
Installation and replacement checks
Before fitting the taper bush, clean the shaft and mating taper, inspect the key arrangement and tighten the bush screws progressively. After seating, verify face alignment and belt tracking before final tensioning.
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 twin-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.
