9E-1B17-0235-0182-9E 1B With exteral gear bearing

1B series is a classic single-row four-point contact ball slewing bearing with external gear, independently developed and standardized for medium-duty rotary mechanical equipment. Adopting a optimized four-point contact structural design, this series of bearings integrates excellent load-bearing performance, stable rotary precision and cost-effective practicability, serving as a core standard component for various light and medium-load rotary transmission scenarios.


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

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

✦ External gear on outer ring – Gear teeth cut directly on the outer ring for direct pinion engagement and power transmission.

✦ Compact cross-section – Thin-section design saves installation space while maintaining structural integrity.

✦ 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.

✦ Light to medium-duty applications – Suited for robotics, indexing tables, medical equipment, and light automation machinery.
