Common Elevator Traction Sheave Models
In the entire operating system of an elevator, the traction sheave is one of the most critical components in power transmission. It determines whether the elevator can run smoothly, steadily, and safely. The friction between the traction sheave and the wire rope generates traction force, enabling the car and counterweight to move up and down. Its material, size, groove shape, and structure directly affect elevator performance.
As different brands and capacities of elevators are widely used, traction sheave models have also become highly diverse. Below, A-FLY Elevator & Escalator Parts Supplier introduces the most common elevator traction sheave models used in maintenance and modernization projects, as well as their application scenarios.
Common Categories of Elevator Traction Sheave Models
Although there are many elevator brands, traction sheaves are generally classified according to wheel diameter, number of grooves, groove type, shaft diameter, and other parameters. The following ranges are the most commonly used in the industry:
1. Common Traction Sheave Models for Small Elevators (Φ240–Φ360mm)
Suitable for elevators with a rated load of 320kg–630kg, low-rise residential elevators, or home lifts.Common models include:
Φ240 – 6 grooves
Φ260 – 6 grooves
Φ320 – 8 grooves
Φ360 – 8 grooves
These models are used for light-duty and low-speed elevators and are often paired with 6×19S or 8×19S elevator wire ropes.
2. Traction Sheave Models for Commercial Elevators (Φ400–Φ520mm)
Used in office buildings, retrofit projects, and shopping malls.Common models include:
Φ400 – 8 grooves
Φ450 – 10 grooves
Φ480 – 10 grooves
Φ520 – 10 grooves
These elevators typically run at higher speeds (1.0–1.75 m/s), so the groove precision and friction characteristics of the traction sheave are more demanding.
3. Traction Sheaves for Heavy-Duty and High-Speed Elevators (Φ550–Φ800mm)
Suitable for hospital elevators, high-rise office elevators, and heavy-duty freight lifts.Common models include:
Φ550 – 10/12 grooves
Φ630 – 12 grooves
Φ720 – 12 grooves
Φ800 – 12 grooves
These sheaves are commonly made from high-strength cast steel or cast iron. Some models use polyurethane (PU) coating to reduce wire rope wear and noise.
Brand-Specific Traction Sheave Compatibility
Different elevator brands generally use specific diameters and groove profiles for permanent-magnet gearless traction machines. Common matching directions include:
MAXIEZ / NEXWAY / ELENESSA: mainly Φ320, Φ450, Φ520
UCA / HCA / HGP: commonly Φ360, Φ400, Φ550
3300 / 5400 / 5500 series elevators: often Φ480, Φ520, Φ630
GEN2 / GEN3 / OH5000: commonly Φ400, Φ480, Φ720
Monospace / EcoSpace elevators: some models use PU-coated sheaves
Because brand models vary greatly, it is essential to confirm dimensions, groove shape, groove spacing, shaft diameter, and other parameters when selecting a traction sheave. Otherwise, it may cause wire rope skipping, slipping, or abnormal wear.
