LYMC-HSW External teeth slewing bearing

The HSW Series is a high-performance single-row four-point contact ball slewing bearing featuring an external gear configuration. Designed according to industry standards (such as JB/T2300), this series is the ideal solution for applications requiring compact mounting arrangements and the ability to handle complex load conditions simultaneously.


Typical Applications:

Construction Machinery and Building Sector

New Energy and Precision Equipment

Specialized Equipment and Material Handling 

General Features and Versatility



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

Thanks to its high cost-performance ratio and compact design, the HSW series is widely used in medium to light-duty rotating machinery, including but not limited to:

✦ Construction Machinery: Truck cranes, excavators, and aerial work platforms-

✦ Material Handling: Slewing conveyors, turntables, and jib cranes.-

✦ Industrial Equipment: Welding manipulators, radar scanning equipment, and medical device

✦ Gear Modification: The modulus, number of teeth, and modification coefficient can be adjusted.

✦ Mounting Holes: Options include threaded holes (Type 1, 2) or through holes (Type 0) to suit your connection method.


Features

✦ Four-Point Contact Design

A single raceway with steel balls contacting at four points.

Capable of simultaneously supporting axial loadsradial loads, and tilting moment loads.

✦ Compact & Lightweight Structure

Single-row design reduces overall height and weight.

Eliminates the need for separate thrust and radial bearing combinations.

✦ High Static & Dynamic Load Capacity

Optimized raceway geometry distributes stress evenly.

Suitable for both intermittent rotation and continuous slow-speed operation.

✦ Smooth & Precise Rotation

Low friction due to point contact geometry.

High rotational accuracy for positioning-critical applications.

✦ Easy Integration & Maintenance

Standard mounting holes (threaded or through) for simple bolting.

Pre-lubricated with grease nipples for easy re-lubrication.

Double-sided seals protect against dust, water, and debris.

✦ Customizable Gear Parameters

Module, number of teeth, and modification coefficient can be adjusted to match your drive system.

✦ Proven Durability

Made from high-strength forged or rolled steel.

Heat-treated raceways and gear teeth for wear resistance.
