Product Characteristics
HT250 gray iron blank specially matched for motors
Low-temperature aging after casting releases internal stress, resisting eccentric deformation under frequent motor start-stop cycles.
Standard bore customized for motor shafts
Bore and keyway machined per national motor standards with precise tolerance, zero loose clearance when fitted on motor output shafts.
Two-stage dynamic balance calibration on outer circle
Secondary balance correction after grooving, matching motor rated speed to suppress high-speed vibration.
Product advantages
Absorb impact from motor startup
Excellent shock absorption of HT250 buffers instantaneous starting force, protecting motor spindle bearings from damage.
Low energy loss and quiet operation
Tight fit between bore and motor shaft eliminates shaking, cutting transmission vibration and overall equipment noise.
Wide compatibility with standard motors
Unified national standard bore sizes fit Y/Y2/Y3 series motors directly without secondary boring processing.

FAQ
Q: Is thickened motor pulley mandatory for high-power heavy-load motors?
A:Reinforced thickened pulleys are recommended for high-torque motors with frequent forward-reverse rotation; standard thickness works for regular light-load operation.
Q:Does pulley shaking come from worn bore or deformed motor shaft?
A:Remove the pulley and check the inner bore first. Scratched or enlarged bore means pulley wear; replace the pulley if the motor shaft remains intact.
Q:Can HT250 motor pulleys fit both vertical and horizontal motors?
A:Same-size pulleys are interchangeable. Only the guard mounting position needs adjustment based on layout; material stress will not be affected by installation angle.
