Controlled machining
Dedicated grinding and finishing areas for bearing rings.
REAL PRODUCTION · CONTROLLED PROCESS
From Prepared Rings to Graded Bearings
LUMI combines controlled ring processing, automated assembly and in-process checks to turn bearing components into consistent finished products for OEM applications.

Dedicated machining zonesFACTORY OVERVIEW
A Connected Flow, Not Isolated Equipment
Grinding, finishing, assembly and process-control stations are organized as a connected production flow. Automation supports repeatable handling and processing, while operators remain part of setup, monitoring and production control.
Automated assembly
Purpose-built stations support repeatable feeding, positioning and pressing.
Process checkpoints
Dimensional and vibration checks create control points within the production flow.
THE CONFIRMED PRODUCTION SEQUENCE
Eight Steps From Ring Preparation to Vibration Grading
The production flow follows the actual sequence from controlled ring processing through assembly, lubrication, closure and final vibration grading.01
Ring Grinding
Inner and outer rings complete controlled grinding before they enter the assembly flow.
02
Inner & Outer Ring Assembly
The prepared inner and outer rings are fed, aligned and combined at the assembly station.
03
Ball Loading
Steel balls are introduced into the combined ring set before they are evenly distributed.
04
Ball Separation
The loaded balls are separated and positioned evenly around the raceway.
05
Cage Installation
The cage is positioned and pressed to retain the separated balls in the assembly.
06
Grease Filling
Lubricant is filled according to the confirmed bearing and application requirement.
07
Shield Sealing
Metal shields are pressed into place to close and protect the bearing assembly.
08
Vibration Testing & Grading
Finished bearings are tested and separated by measured vibration level before release.
INSIDE THE PROCESS
Real Production, Step by Step
Real production footage shows key stages across assembly, ball positioning and bearing closure.Featured process
STEP 04
Ball Separation
The separation head distributes loaded steel balls evenly around the raceway.
STEP 05
Cage Installation
The retainer is positioned and pressed around the separated ball set.
STEP 07
Shield Sealing
Multiple press stations install metal shields before finished bearings are collected.

AUTOMATION & PROCESS CONTROL
Control Points Within the Production Flow
Automated equipment supports repeatable handling and processing, but consistency also depends on defined checkpoints. The footage shows an inline contact measurement station checking a ring during production. Final test requirements are then aligned with the bearing specification and application.

- In-process ring measurement
- Vibration testing and level-based grading
- Operator setup, monitoring and process oversight
FROM MANUFACTURING TO QUALITY
Production Consistency Continues Into Inspection and Validation
Vibration grading closes the manufacturing flow. Further inspection and validation continue within LUMI's quality process.
