Chapter 10: Case Studies and DSBR's Field Application Success Stories

1. Mining Equipment – Chile

Problem:
A major copper mine in Chile experienced repeated bearing failures in their conveyor pulleys every 3–4 months, causing critical downtime.

Diagnosis:
Analysis showed contamination and improper grease cycles, leading to early-stage spalling in the tapered roller bearings.

DSBR Solution:

• Replaced bearings with double-shielded tapered roller bearings with optimized raceway finish

• Introduced automatic lubrication system with DSBR-recommended grease

• Implemented weekly vibration monitoring plan

Results:

• MTBF (Mean Time Between Failures) extended from 4 months to 18+ months

• Maintenance cost reduced by 40%

• Zero unplanned shutdowns in 2 years

2. Heavy-Duty Trucks – Brazil Aftermarket

Problem:
A fleet operator reported excessive wear in wheel hub bearings (VKBA-type repair kits) on long-haul trucks after 60,000 km.

Diagnosis:

• Factory-installed low-grade aftermarket bearings

• Incorrect preload during installation

• Inconsistent sealing performance in humid environments

DSBR Solution:

• Supplied DSBR VKBA1948 repair kits with OEM-grade seals and grease

• Provided preload instruction manuals and installation training

• Offered after-sales support and tracking for each unit

Results:

• Bearing lifespan extended to 150,000 km+

• Customer satisfaction improved with 25% fewer bearing replacements

• Fleet maintenance team adopted DSBR kits as standard

3. Steel Plant Furnace Rollers – India

Problem:
A hot rolling mill’s furnace roller line suffered high-temperature bearing degradation every 6 weeks.

DSBR Intervention:

• Delivered heat-treated cylindrical roller bearings with advanced cage design

• Integrated temperature monitoring sensors

• Trained engineers on lubrication intervals and load balancing

Outcome:

• Bearing failure interval improved from 6 weeks to 10 months

• Reduced total bearing costs by over 60% per annum

• Achieved ISO quality audit compliance using DSBR traceability reports

4. Agricultural Machinery – Eastern Europe

Issue:
A leading combine harvester manufacturer faced product returns due to premature bearing failure in transmission shafts.

Investigation:

• Tolerance mismatch between shaft and bearing ID

• Inadequate surface hardness of inner race

DSBR Engineering Support:

• Customized bearing tolerance class P5 for critical fits

• Applied HRC 64-65 surface hardening on raceways

• Introduced factory audit checklist to detect improper fits

Impact:

• Warranty claim rate dropped by 70%

• Product line re-approved by key OEM buyer

• Strengthened DSBR’s reputation in Eastern European agriculture market
