Escalators Elevators

WGB Bearing is a member of China Elevator Association, and an editorial board member of JB/T 13348-2017 for Roller Bearings for Elevator Traction Machine. Meanwhile WGB is a council member of China Bearing Industry Association.

Back to the year 2008, considering the specific requirements by elevators and escalators, WGB specially designed and precisely engineered WGB® HQBE series spherical roller bearings for traction machines, wheeling system, and elevator drives.

As of now, more than 1 million elevators and elevators have been globally operating with WGB bearings.

Performance and Quality

• Lower Vibration and Nosie

Engineered with tighter geometry tolerance, statistical process control, improved surface roughness to optimize the bearing vibration and noise in motion

• Higher Reliability and Longer Life

Optimize the internal design, adjust the surface contact ratio and position to increase the load ratings and exited the bearing life

• Long-term sealing system

Two-side sealings, double lips and made of NBR or FPM; sealing grooves precisely machined to make the leakage as low as 5%

• Long-term Lubrication system

Pre-lubrication with specific types and amounts as per requirements; longer lubrication time; relubrication through grooves and holes on outer rings
