End-to-End Design Process
Our closed-loop workflow ensures robust outcomes:
Discover
Understand real-world duty cycles, load variations, operating speeds and environmental challenges to define accurate design requirements and application specific needs.
Specify
Select appropriate bearing type, geometry, internal clearance, cage material and steel grade to balance performance, durability, efficiency and customer cost targets.
Design
Develop detailed CAD models incorporating precise tolerances, GD&T standards, manufacturability checks and assembly feasibility to ensure robust, production-ready bearing designs.
Simulate
Run advanced simulations in ANSYS including stress, fatigue, thermal behaviour and NVH analysis, validating reliability before moving to prototyping and physical trials.
Prototype
Build rapid prototypes using in-house CNC machining, heat treatment and grinding facilities, enabling quick feedback, early validation and improved design efficiency.
Validate
Conduct endurance testing, noise and vibration checks and environmental simulations such as dust, humidity and salt spray for proven bearing reliability.
Release
Freeze final bearing design, prepare complete PPAP and APQP documentation and support customer SOP ramp-up with technical guidance and on-site assistance.
Prototype Development & Testing
We don’t just design—we prove designs in real conditions.
- Prototype Build: In-house prototypes for early trials.
- Endurance Testing: Life (L10), accelerated fatigue tests.
- NVH Testing: Noise and vibration checks for motors and vehicles.
- Environmental Tests: Salt spray, dust ingress, humidity.
- Metallurgical Validation: Hardness, case depth, microstructure, material chemistry.
Custom Rigs: We also design test rigs for customer-specific applications.
Project Management & Delivery
Every project is handled with an integrated project management approach:
- Clear objectives aligned with customer needs.
- Progress tracking through milestones and reviews.
- Documentation: Control plans, DFMEA, PFMEA, PPAP packs.
- Customer communication at every stage for transparency.
- Market support after launch, ensuring feedback-driven improvements.
This ensures on-time delivery and risk-free launches for OEMs and industrial clients alike.

Frequently Asked Questions (FAQs)
What makes RAS Bearings’ design and development different from other companies?
RAS Bearings combines advanced design software, Zero PPM recognition, in-house validation rigs, and years of OEM experience. This blend of technology and expertise ensures our bearing designs are more reliable, precise, and globally benchmarked than competitors.
Do you design bearings only for the automotive sector?
No. While automotive is an important focus, we also design bearings for industrial machinery, pumps, motors, construction equipment, and agricultural machines. Our design centre supports multiple industries with customised solutions.
What software and tools do you use for bearing design?
We use PRO-E (Creo), CATIA, and ANSYS for CAD/CAE design, simulation, and analysis. These tools help us check geometry, stress, fatigue, thermal behaviour, and NVH performance before moving into prototypes.
Can you develop a customised bearing for my application?
Yes. We customize geometry, cage material, clearance, lubrication, seals, and coatings to perfectly match your machine’s load, speed and environmental needs. Our aim is to give you a fit-for-purpose design.
How do you support OEM projects during development?
We provide full APQP and PPAP documentation, along with DFMEA, PFMEA and project management support. Our team works closely with OEMs to ensure smooth design validation and SOP ramp-up.
How long does it take to design and validate a new bearing?
Timelines vary by complexity, but thanks to our in-house design software, prototype facilities, and validation rigs, we can design, prototype, and test bearings faster than most competitors.
What kind of tests are done on your designs?
We run computer simulations (stress, fatigue, NVH) and physical tests like endurance rigs, noise/vibration checks, salt spray corrosion tests, and dust/humidity trials. This ensures bearings are proven before launch.
How do you ensure your designs meet international standards?
All RAS Bearings designs follow IS/ISO/DIN standards. We also undergo OEM audits and prepare PPAP documentation to align with international quality requirements.
