9I-1B30-0995-0558-1B Type with inner gear

The 1B series is a standardized single-row four-point contact ball slewing bearing with internal gear structure, specially designed for light to medium-duty rotary mechanical systems. Adopting mature industrial manufacturing techniques and optimized gothic arch raceway design, the 1B internal gear slewing bearing delivers stable comprehensive load capacity, precise rotational performance and excellent cost efficiency. It has become a universal and reliable core component widely used in industrial automation, mobile engineering machinery and various rotary drive equipment.



Typical Applications:

Aerial work platforms and man lifts

Solar tracking systems

Radar and antenna positioning systems

Materials handling equipment




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

✦ Internal gear on inner ring – Gear teeth cut on the inner ring for direct pinion engagement and compact drive integration.

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

✦ Compact thin-section design – Optimized cross-section saves installation space in tight layouts.

✦ 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.
