9O-1B35-0867-1122-1B Design without Gear

The standard toothless four-point contact ball slewing bearing is a universal, versatile rotary component engineered for light to medium-duty mechanical rotation scenarios. Following mature industrial standard specifications, this gearless slewing ring adopts a simplified integrated ring structure with no internal or external gear teeth. It focuses on pure rotational stability, flexible assembly compatibility and low operational attrition, serving as a cost-effective and highly adaptable core part for modern automated machinery, mobile rotary equipment and general industrial mechanical systems.


Typical Applications:

Custom-built handling and positioning equipment

Systems where belt or friction drives are preferred over gear drives

Noise-sensitive environments where gear noise must be minimized

Solar tracking and antenna positioning systems

Light to medium-duty turntables and rotary indexing tables


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

✦ Four-point ball contact geometry – Single-row configuration with balls contacting the raceway at four points.

✦ Toothless ring surfaces – Both inner and outer rings have plain cylindrical faces without gear teeth.

✦ Induction-hardened raceways – Rolling paths hardened for wear resistance and extended fatigue life.

✦ Sealed raceway enclosure – Equipped with NBR rubber lip seals on both sides of the rolling chamber.

✦ Alloy steel ring material – Rings manufactured from high-strength alloy steel grades.

✦ Equispaced mounting holes – Both rings drilled with a uniform pattern of bolt holes for bolted attachment.


Features





✦ Flexible drive integration – Toothless rings allow custom drive selection, including pinions, belts, or friction wheels.

✦ Simplified system design – No gear teeth means one less precision component to specify and maintain.

✦ Cost-effective solution – Eliminating gear cutting reduces manufacturing cost compared to geared versions.

✦ Easier cleaning and maintenance – Smooth ring surfaces do not trap debris or contaminants.

✦ Reduced operating noise – No gear meshing ensures quieter machine operation.

✦ Lower rotational resistance – Friction-free toothless surface contributes to smooth, low-torque rotation.
