Product Characteristics
Precisely cast HT250 gray iron sheave
Stress relief aging after casting eliminates internal stress, preventing out-of-round deformation under long continuous operation.
Integrated smooth single/multi-groove machining
Groove walls without sharp edges, curve matched to V-belts, ultra-tight tolerance for groove spacing.
Dual-compatible bore design for straight mounting & taper lock
Supports flat key direct assembly and taper bush locking, compatible with fan and reducer drive shafts.
Product advantages
Stable internal stress and great dynamic balance
Aging treatment avoids post-production deformation, minimizing vibration at high speed and eccentric wear on bearings.
Gentle contact protects transmission belts
Arc-shaped grooves prevent cutting belt edges, reducing cracking and delamination to extend belt service cycle.
Flexible mounting reduces inventory cost
One sheave model works with both flat key and taper bush, no need to stock multiple customized pulley sizes.

FAQ
Q: Will stress-relieved HT250 sheave turn out of round after long operation?
A:No under stable normal loads. Severe continuous shock or overheat causes slow deformation, so it is not suitable for heavy impact equipment.
Q:Is there any difference in tension adjustment between single-groove and multi-groove sheaves?
A:All belts on multi-groove sheaves must keep identical tension, while single-groove only needs one calibration. Uneven tension causes individual belt abrasion.
Q:How fast will uncoated HT250 sheave rust in moist workshops?
A:Bare sheaves stay intact for months in dry workshops, but surface rust spots appear within one week under humid conditions. Anti-rust paint is suggested before delivery.
