How is the shaft connected to the wheel in heavy-duty pulleys?

For medium and heavy-duty pulleys, the shafts and wheels are connected by expansion sleeves to solve stress concentration issues.

What is the lead time for production?

The average lead time is 1-3 months during peak season and one month during the off-season.

Key features

Advanced Cast Welded Structure: Adopts cast welded structure and expansion sleeve connection to solve stress concentration and eliminate welding internal stress.

High Precision Static Balance: Achieves G40 static balance accuracy with total radial runout of outer circle less than 1mm after roller casting.

Extended Rotational Fatigue Strength: Guaranteed rotational fatigue strength of over 10^8 cycles for the pulley including welding parts.

Customizable Color Options: Color is customized according to specific customer requirements and application scenarios.

Advanced Finite Element Analysis: Uses finite element analysis and optimization calculations to improve structure and reduce structural stress.

Non-Destructive Weld Testing: Circumferential and longitudinal welds undergo non-destructive testing; hub casting undergoes magnetic particle or ultrasonic testing.

Large Scale Production Capability: Capable of producing pulleys for belt width up to 2.4m, diameter up to 1.8m, and max tension up to 300 tons.
