HSB.50.4030-HS Non Gear

The HSB series features toothless four-point contact ball slewing bearings engineered for versatile light and medium-duty rotary applications. Eliminating traditional internal and external gear structures, this non-geared slewing ring lineup offers flexible, adaptable rotary solutions for machinery that relies on external drive assemblies. Built with precision-optimized raceway geometry and rigorous manufacturing standards, HSB toothless slewing bearings deliver outstanding structural stability, consistent rotary precision and remarkable cost-effectiveness for diverse industrial and commercial equipment.



Typical Applications:

Construction machinery such as cranes and excavators

Aerial work platforms and man lifts

Solar tracking systems

Materials handling equipment

Industrial turntables and positioning systems


High load-carrying capacity
Resistance to high and low temperatures
Noise-free operation
Strictly controlled tolerances and appropriate internal clearance
Long service life and low maintenance requirements
Prevention of unexpected downtime (avoiding bearing fracture, seizure, and safety incidents caused by such failures, with anti-tilting capability)

Characteristics

✦ No gear teeth – Smooth inner and outer rings without teeth for customized drive solutions.

✦ Four-point ball contact – Single-row design handles axial, radial, and tilting moment loads simultaneously.

✦ High-speed capability – Optimized geometry for smooth rotation at elevated speeds.

✦ Induction-hardened raceways – Rolling surfaces hardened for wear resistance and extended service life.

✦ Double lip seals – Fitted with NBR seals on both sides to keep contaminants out and retain lubricant.

✦ Pre-drilled mounting holes – Both rings feature equispaced bolt holes for quick and secure installation.
