- Solutions developed with cross-functional teamwork.
- Delivery timelines monitored for on-time outcomes.
Our dedicated project managers ensure clarity, accountability and smooth execution from concept to SOP.
Testing & Validation: Where Innovation Meets Proof
Validation is the soul of R&D. At RAS Bearings, we combine computer simulations with real-world physical tests to confirm performance before serial production.
- Computerised Life Testing Rigs – L10 endurance, accelerated fatigue tests.
- Noise & Vibration Analysis – For electric motors, automotive hubs and critical applications.
- Environmental Testing – Salt spray, dust ingress and humidity exposure.
- Dimensional & Geometric Checks – Roundness, waviness, surface finish.
By validating at every step, we deliver bearings that are quiet, durable and application-ready.
Our Metallurgical & Measurement Laboratory
- Spectrometer – For chemical composition of steels.
- Microscope – For case depth, inclusions and grain structure.
- Rockwell & Vickers Hardness Testers – For core and case hardness checks.
- Surface & Form Testers – To measure roughness, roundness and profile accuracy.
These facilities help us verify material quality, heat treatment consistency and process discipline.
Future-Ready Facilities
- Special-Purpose Machines (SPMs) for bearing-specific trials.
- Automated Testing Rigs for endurance and noise validation.
- Prototype-to-Production Integration that reduces lead times.
- Digital Tools for design simulation and soft validation.
This makes us a future-ready partner capable of handling the most demanding customer needs.

Frequently Asked Questions (FAQs)
Can RAS Bearings design custom bearings for my machine or industry?
Yes. We can customize geometry, cages, clearances, lubricants, seals and coatings. Whether it’s for automotive, industrial, agriculture or export applications, we adapt our designs to your exact duty cycle and cost needs.
How do you test and validate your bearing designs?
We use a mix of lab tests and real-world checks. This includes computerised life testing rigs, noise and vibration analysis, environmental simulations (dust, humidity, salt spray) and metallurgical checks like hardness and microstructure.
Do you provide PPAP documentation for OEM projects?
Yes. We support full APQP and PPAP processes. Customers receive Control Plans, PFMEA, MSA studies and complete test reports so new projects move smoothly into production.
What kind of testing equipment do you have in your R&D lab?
Our R&D centre has a spectrometer for chemical analysis, microscopes for microstructure checks, Rockwell and Vickers hardness testers, surface and roundness testers and endurance rigs for life testing.
Can RAS Bearings support me during field trials?
Yes. Our Application Engineers visit your site to supervise prototype installation, lubrication planning and performance tracking. We work with your team until the solution is proven.
How long does it take to develop a new bearing design?
Development time depends on complexity. Thanks to our in-house CNC, heat treatment, grinding and testing facilities, we can prototype and validate faster than most competitors.
Can you handle both small batches and mass production?
Yes. We start with small prototype batches for validation, then move to serial production using our interconnected grinding lines and automated assembly systems. This makes scaling seamless.
How do you ensure bearings work in Indian conditions?
We design bearings to withstand dust, heavy loads, stop-start traffic, humidity and heat. Surface treatments like chrome plating and phosphating add extra protection against rust and wear.
Do you also offer solutions for noise and vibration problems?
Yes. We use vibration analysis, roller grouping and superfinishing processes to reduce noise and vibration. This is especially useful for electric motors, pumps and automotive hubs.
