Special Rotary Bearing for TBM FB-132-32-957

Overview

The FB-132-32-957 TBM special rotary bearing is a purpose-built articulated ball bearing for TBM screw conveyors, designed as the core torque-transmission component for tunnel boring machine power head screw conveyor systems. This bearing delivers stable torque transfer even under simultaneous axial load, radial load and overturning moment, while supporting a certain degree of swing to adapt to the complex variable conditions of underground tunneling. It is the preferred critical component for industrial procurement professionals, tunnel engineering contractors and heavy tunneling machinery maintenance teams.

Technical Specifications & Dimensional Parameters

Key Features & Performance Advantages

Compound Load Adaptability & Stable Torque Transmission

The FB-132-32-957 articulated ball bearing maintains uninterrupted torque transmission under combined axial, radial and overturning loads, fully meeting the heavy-load operation requirements of TBM screw conveyors in both hard rock and soft soil tunneling scenarios.

Articulated Swing Design for Complex Working Conditions

Through arc-shaped tooth meshing and spherical surface fit, the inner ring can realize a certain angle of swing with the outer ring fixed, adapting to equipment offset and vibration during TBM tunneling, and improving the smoothness of gear transmission.

Optimized Sealing & Lubrication System

It adopts a combined sealing ring and sealing strip structure for reliable dust prevention and oil leakage prevention. Multiple rows of oil passages are machined on the outer side of the spherical internal gear ring, leading to the spherical surface and tooth end face, ensuring sufficient lubrication of meshing parts and extending service life.

High-strength Integrated Structural Design

The bearing consists of a sealed end cap, slewing bearing outer ring, spherical internal gear ring, upper outer gear ring, inner ring, cage, cylindrical rollers and high-strength connecting screws, with compact structure, easy processing and stable long-term operation.

Applications & Compatible Equipment

This product is mainly used in screw conveyor power heads of Tunnel Boring Machines (TBM), widely compatible with mainstream TBM equipment for subway tunnel construction, water conservancy tunnel engineering, urban comprehensive pipe gallery tunneling, hard rock tunnel excavation and underground mine roadway construction.

Installation, Operation & Maintenance Guidelines

Installation Precautions

Before installation, check the dimensional accuracy and surface integrity of the bearing, clean equipment mating surfaces, and tighten connecting screws in diagonal order with specified torque to ensure uniform stress.

Operation & Maintenance Rules

During operation, monitor bearing temperature and vibration in real time, avoid long-term overload operation, and stop for inspection immediately if abnormal noise or jamming occurs. Regularly add special extreme pressure lithium-based grease through preset oil passages, check sealing integrity, inspect tooth surface and raceway wear, and replace damaged components in a timely manner.
